Hyperion Emeter II Bedienungsanleitung

Emeter v2 Quick Guide 2.09 rev. Feb 9 2009

See http://media.hyperion.hk/dn/em2 for updates to documentation, PC software, and Firmware

Introduction

The Hyperion Emeter II can carry out an enormous range of functions related to Electric Powered models and

small vehicles, and has been designed with ease of use as a prime objective. On-screen help, a menu system

and friendly error messages all contribute to this objective while in the field or at the lab.

This Quick Guide describes the scope of Emeter II and how to make it work for you, in a sequence which

matches the on-screen menus. The Emeter’s own On-screen help is a subset of this information intended to

answer most questions at the field. The full Emeter II User Manual (Download from link above) goes into

greater depth with explanations of many of the issues surrounding Electric Power and Radio Control models.

The Emeter II System consists of two major components:

•The pocket sized case houses the display screen, an SD Card slot, buttons for menu navigation, a

potentiometer to drive pulse-width devices such as servos and motor controllers, an optical tachometer,

and an internal battery pack with onboard charger.

•A Remote Data Unit which, with its small size can be fitted to the power system (RC model, robot,

scooter, etc…) to log data. At the end of the logging period, the captured data can be copied to the

Emeter II for display, without the need for a Personal Computer.

In addition, the Emeter v2 comes with two cables in the box:

-- A Data Cable (aka “RDU Cable”, #HP-EM2-4PINCBL). It has a locking Molex 4-pin connector on one side

which fits the Emeter v2 at bottom-right port. The other side has 5-pin female connector (with one pin

“blanked”). This side fits the RDU so that the RDU can transfer files to Emeter, and communicate during Bench

testing or RDU setup. The same side also fits Hyperion TITAN series ESC, for programming via Emeter.

-- A Power Cable (#HP-EM2-PWRCBL) with 4.5mm plug on one side, and tinned wires on the other. The

Emeter contains a 5-cell 750mAh NiMH battery inside, and an INTERNAL CHARGER. You should never connect

a battery charger to this power input. Instead, simply use any 12V~15V DC power supply with 120mA or

higher capacity (such as a 13.8V DC power supply, Automotive battery, or discarded 12V “Wall PS” from some

old toy, router, etc). Please take time now to fit appropriate connectors to this cable, and plug in your

Emeter to a 12-15V power source for charging. See details below for charge rate and time.

Terminology

RDU – The Remote Data Unit contains data storage, and sensors for measuring voltage, current, height

(altitude from start point), ambient temperature and other data. In addition the RDU has input/output

connectivity to a receiver or pulse-width driver such that throttle position can be recorded or remote on/off of

logging controlled. The RDU can record peak currents up to 150A with stock wiring (up to 300A, 5 sec,

modified), with a maximum of 70V input. There are also optional sensors available for up to three external

temperatures and phase tachometer for brushless motors at this time, with other sensors planned for 2009.

Before using the RDU, it is necessary to solder on the connectors of your choice to the RED/BLACK wires

marked INPUT (Battery, DC PS) and LOAD (Motor, Charger, Discharger, etc) on RDU bottom. The connectors

must be high-quality and matched in size to the maximum currents you expect to draw. Although the RDU is

protected against accidental connection with polarity reversed, the ESC which is normally connected to the

LOAD side of the RDU, is likely not protected and will be destroyed by reversed polarity. So take great care with

connector polarity.

ESC - Electronic Speed Controller is used to vary the speed of the model’s motors

BEC - Battery Eliminator Circuitry, optionally included in the ESC, is used to power receiver/servos from main

power pack instead of a separate receiver pack

SD Card – is a mass data storage device which may also be used for transfer of data between a PC and the

Emeter II, including:

•Emeter II and RDU firmware updates

•Files for On-line screen help

•Prop constants data

•Data logs

•Parameters for user-programmable servo or ESC drivers

An SD card is not included but is strongly suggested for complete functionality. Standard (or Mini/Micro in adapter) SD SDHC

cards up to 4Gb are supported. They must be formatted as FAT16 or FAT32.

Phase Tachometer sensor – (option part # HP-EM2-TACHBL) has a single wire which should be connected to

any of the three wires into a brushless motor, and the 3 pin plug which fits the RDU socket labelled ‘RPM’.

External Temp 1,2,3 sensors – (option parts #HP-EM2-TMP1 and #HP-EM2-TMP23) Note that Temp#1 must

be purchased in order to add temps #2 and #3, as only TEMP#1 connects direct to RDU (2,3 connect via #1).

On Screen Help and Navigation

Features are accessed by selection from a multi-level menu. Button numbers are shown in quotes for example

‘A’, ‘B’, ‘C’ or ‘D’ and have an abbreviated description on the bottom row of the display. Button ‘A’ on the MAIN

menu will display Tips on RDU and Emeter II firmware version upgrades. Navigation through the menus is

achieved by pressing ‘D’ until the required menu item shows in larger characters. Once this occurs,

•press ‘B’ to display screen help relating to the selected function or

•press ‘C’ to go to the selected function.

There are two basic modes of operation – ‘Bench-Test’ mode in which the RDU and the Emeter II are connected

for use together, and ‘In-Action’ mode where the RDU is used alone. In Bench-Test mode, RDU is cabled to the

Emeter and data is recorded directly to the Emeter’s SD card, whereas In-Action mode stores the data in the

remote RDU from which it is later copied to the Emeter II SD card. After switching the Emeter II on, the

function which was in use at the previous switch off time will re-appear. In most cases, ‘A’ will cause a return to

the previous, higher menu item or screen. Certain actions may cause deletion of data which could be critical.

You will be warned if this is the case and requested to confirm the action.

OPERATION NOTES

EMETER BASIC SETUP

Function Screen/Mode Cables/Wiring

1.1 Internal battery Charging 12-15 volt supply with the supplied 4.5mm plug

The Emeter II will automatically charge while connected to 12-15V PS whether the unit is in use, or switched off.

The Emeter can be used while connected to 12-15V power source (i.e. during bench testing can be left connected)

Charging will occur at 85 ma and take 9 - 12 hours at this rate from a fully discharged state.

The battery will last between 18 and 50 hours, depending on use of screen backlight, connection to RDU and other factors.

Main menu shows internal battery charge state indicator. Reconnect to 12-15V PS before this falls to 0%. The date and time

will need to be reset if the internal battery is allowed to go flat.

moving models. Only Bench-test mode can record power, efficiency and thrust. See manual for details.

DATA LOGGING

Function Screen/Mode Cables/Wiring

6.1 Data Logging Bench-Test

mode READINGS>ANALYSER or

READINGS > BATTERY RDU + RDU cable + optional RPM or

temperature sensors

Press ‘C’ to log readings to SD card or to cease logging under full user control. Each start creates a new log file with unique file

number and showing date and time. Blinking message on screen acts as recording indicator.

Warning, do NOT power off the Emeter II while logging is in progress.

Press ‘C’ on BATTERY or ANALYSER screens to stop logging first.

6.2 Set RDU data logging

parameters for the In-

Action mode

MAIN MENU>RDU SETUP RDU + RDU cable

Set Trigger type for start of logging:

•Amps – start logging when actual current exceeds specified trigger amps

If amps fall below trigger level, then logging will stop if the RECORD SECS (expiry time) has elapsed.

•Increase amps above trigger current to resume logging. There will be multiple sets of data readings – one set for each time the

actual current rises above then falls below the specified trigger amps. These different sets will all be down-loaded to the SD

card as a single file. The time display resets to 0 at the start of each set. For continuous logging after amps start, set expiry

record time = 0 or very high. If the RDU is unplugged from the main power source, then, once the RDU and power source are

re-connected, a new data log file will be created. The download action, if chosen, will copy all files from the RDU to the SD card

•Time – this option is used for motor-less models which cannot use an AMPS based trigger. Logging begins once start delay

seconds have elapsed after RDU connected to main Power Pack and continues until the RDU is disconnected or the record time

expires

•Manual – logging controlled by signal from spare receiver channel. Pulse width < 1300 μs. will stop logging and > 1700 μs

starts logging

Set recording expiry time (in secs.) for data logging session or zero for unlimited length

Set sample rate from 4 per second to 8 secs. per sample. This sample rate applies to both In-Action and Bench-Test modes.

Save logging parameters by pressing ‘A’

6.3 Set up RDU logging of:

Amps, Volts, RPM, Ambient

temp, 3 external temps,

height

RDU + optional RPM and temperature sensors

NO RDU cable from RDU to Emeter II

3 wire cable from spare Rx channel to RDU

Rx input (for manual logging start)

- Connect optional rpm sensor to RDU RPM port and any one of brushless motor input leads. Note that the ambient temperature

and height will be recorded automatically by sensors built in to the RDU. Connect option temp. sensor #1 to the 4 pin plug on the

RDU marked ‘AUX’, and connect option Temps #2 and #3 to Temp #1. Where possible, use adhesive tape to prevent movement

between the sensors and target to ensure good contact (example, motor, power pack and ESC).

- Connect RDU main power wires to ESC. When ready to run model, connect RDU to power pack. Green LED should flash on RDU

at the sample rate. Green LED changes to red whilst logging is in progress. Time based logging will stop when the Record Secs. on

the RDU SET-UP have elapsed or the RDU is disconnected from the model’s power-pack.

Amps triggered logging will stop when the Record Secs have elapsed AND the current drops below the trigger amps.

Logging will resume again if the current rises above the trigger amps; a fresh Record Secs time will apply

TIMERS & STOPWATCHES

General notes on Timers and Stopwatches - On entering any one of the three stopwatch screens, a check is made for any

previous timing data for this particular stopwatch mode. If this exists, then the stopwatch will display the previous data. If the

data was initially captured using a different stopwatch mode, then a warning is issued and the option to clear data is given. All

stopwatch and countdown functions will remain running while using other Emeter II screens.

Function Screen/Mode Cables/Wiring

7.1 Stopwatch/lap count mode MAIN>STOPWATCHES>LAP COUNT None

DRIVER left Port

(Brown wire is Negative, Orange is Signal)

FIRST, note that the POT Driver Dial on Emeter, and its two servo driver ports, are almost always “active” no matter which Emeter

screen one is viewing at the moment. So BE CAREFUL whenever an ESC and motor are connected, to avoid unintentional starts!

Connection Sequence:

* TURN POT DIAL on Emeter to Minimum Position (fully counter clockwise, ~900uS)

* Press Button ‘B’ (Type) to select ESC voltage rating (rating is printed on ESC heat sinks)

* Connect ESC 3-pin to leftmost Servo Driver Port at rear of Emeter

* ONLY OPTO ESC (50v and 68v types): also connect a 4.8v~6.0v Rx battery pack to the other Servo Driver Port

* Connect Main Power Pack to ESC Red/Black Input Wires

* Press ‘D’ (Go)

Select the function you wish to change with button ‘D’ (Next) and use ‘C’ (Set) to scroll through options. When all settings are as

you wish, press ‘B’ (Save). Settings are made one-at-a-time, so it may take some time to finish. Press ‘A’ (Exit) to leave without

making changes. See Full Manual for details.

8.3 Atlas Digital Servo

See Full Manual for more details

MANUAL & AUTOMATED TESTING (for Servos, Motor/ESC, and other pulse-width-driven devices)

Note: In v2.08 Main Menu Item “SERVO TESTER” has been renamed “TESTING”. TESTING now leads to a sub-menu, with SERVO

TESTER (same as previous) and RUN PROFILE options. RUN PROFILE has been completely redesigned and greatly enhanced. See

below, and Full Manual for more details. While on TESTING at Main Menu, you may press ‘B’ (Help) for tips on both functions…

Function Screen/Mode Cables/Wiring

8.4 Servo Cycle Testing –

simple start/end MAIN>TESTING>SERVO TESTER Servo and Rx battery

Plug in servo and receiver battery as per on-screen diagram. Note, servo and battery sockets are interchangeable.

From EM firmware release 2.06 onwards, there are two alternative techniques for specifying a test run:

•Simple start/end points chosen, with servo cycling between these two limits

•User defined profile: created on a PC and loaded onto the SD Card, or create directly on the Emeter II. (see next section)

Simple start/end point. As instructed on the screen, move the potentiometer (pot) to the start position (0%) and press ‘D’

(next). Move POT DIAL to end position (100%) and press ‘D’ (Start). SEE DIAGRAM PG. 2

Both the start and end positions will display the pulse width which will be in the approximate range 1000 – 2000 microseconds

The servo will cycle between the two end points.

Press ‘C’ to stop cycle testing

8.5 Servo Testing by Profile MAIN>TESTING>RUN PROFILE Servo and 4.8~6.0V Rx battery

Creation of a test profile. A test profile routine consists of a series of records, each containing a signal pulse width in

microseconds and a delay time in milliseconds. This tells the servo how far to move and how long it should stay there. The profile

itself can be created on a Personal Computer as a simple text file with 8-character-max name, but must have a .dat extension

and must sit in the data directory on the Emeter’s SD card. The header record is followed by any number of position/time records:

PW-uS,DELAY-mS (These notes in parentheses should NOT appear in the Test Profile File!)

01500,01000 (Atlas Servo Center, 1 second)

01000,00500 (Atlas Servo Full Right, 0.5 second)

02000,00500 (Atlas Servo Full Left, 0.5 second)

‘SERVTEST.dat’ above is included as a sample in the v2.08 upgrade file package, DATA folder.

See Full manual for full details on creating profiles via PC text editor or directly on Emeter.

Use of existing profile. At the RUN PROFILE screen press ‘D’ (Next) to select a profile from the list. Press ‘‘C’ (go), which then

takes you to the PROFILE TEST screen, where various automation options can be chosen.

The eight parameters below can be set by pressing ‘C’ (Cfg) button, then ‘D’ (Next) to select a parameter, and INC/DEC buttons to

set the values for that parameter. When all parameters are set as you like, press ‘A’ (Save)

REPEAT determines whether the test profile is to be executed Continuously or Once Only

LOGGING (Yes/No): Turns logging ON of OFF during the test run, as desired.

THE FOLLOWING PARAMETERS WILL AUTO-TERMINATE THE TEST according to your settings and the corresponding data streaming

into the Emeter from RDU. They therefore require that the RDU be connected to the Emeter, and that the RDU is powered via its

INPUT leads (usually the main power pack in a motor test system). If RDU is NOT connected, these settings are ignored.

VOLTAGE (min): 1V~70V in 0.2V steps

CURRENT (max): 1A~200A in 1A steps

TMP1, 2, 3 (max): 1~120 degrees Celsius in 1 deg. Steps (note that TMP only require RDU connection to Emeter, not MPP)

mAh-OUT (max): 10mAh~65000mAh in 10mAh steps

Each of the settings above has default setting of OFF, meaning that they will not affect testing in that case.

See Full Manual for more information on using Profiles and the auto-terminate settings above.

Deletion of unwanted profile: From PROFILE TEST screen, press ‘B’ to delete the current profile and ‘D’ to confirm deletion.

You will then be returned to the RUN PROFILE screen, where you may select, or create, a different routine.

8.6 Auto Power System Test MAIN>TESTING>RUN PROFILE>PROFILETEST Servo and Rx battery

This is identical to the above automated servo testing from a profile, except that the ESC replaces the servo, and the AUTO-

TERMINATE settings listed above become VERY useful… As such, users will have the option of stopping tests automatically if any of

TMP1, 2, 3, mAh-OUT, or CURRENT exceed max selected value, or if VOLTAGE falls below the minimum you have set. Very handy

for automating testing, and insuring that no equipment is over-stressed!!

For Power System testing, we assume that you will want the LOGGING option set to YES. Press ‘D’ (Strt) to start the automated

test. When ‘D’ (Stop) button is pressed, the system will return to the first line in the Profile File and output whatever pulse-width is

specified in the profile. If logging is ON, the Log will also stop when ‘D’ (Stop) is pressed.

We strongly recommend that any test profile which is to be used for driving an ESC and a motor should have the first

few seconds in the profile set to a motor-off signal such as 900 uS. If, during a profile controlled ESC motor test, there is an

urgent need to terminate the run quickly, then it is only necessary to press ‘D’ Stop if first line is 900uS.

See Full Manual for more detail and tips, and a sample Motor Test Routine (MOTRTEST.dat included in v2.08 upgrade file package)

8.7 Manual Servo/ESC Driving From any screen at any time ESC (opto esc require 4.8-6.0V Rx battery)

Connect Emeter II, Rx battery and servo or ESC as for Servo Cycle Testing, but exit from the cycle testing screen.

Rx battery MUST BE LEFT OUT if the ESC has BEC circuitry, UNLESS the +V wire to the ESC is disconnected

Set the Emeter POT DIAL to the throttle closed position - fully anticlockwise.

For model aircraft, initially test for correct wiring and functioning with no propeller, as a safety precaution.

Turn POT to drive the Servo or ESC.

Hold ‘D’ for 3 secs. to allow access to

Upgrade and Calibrate functions

RDU + RDU cable

Plug RDU into power source with known voltage. Increment/decrement to match voltage. Save twice

9.2 Calibrate Current (amps)

Plug RDU into power source. Discharge at known current. Increment/decrement to match amps. Save twice.

9.3 Upgrade Emeter II

Firmware version Before switch-on, press Buttons ‘A’, ‘B’, ‘C’

and ‘D’ while switching power to Emeter II SD card

Firmware loader process checks for file EMFW.bin on SD card and, if found, loads the new firmware version into the Emeter II.

9.4 Upgrade RDU

Firmware version MAIN>RDU SETUP

Hold ‘D’ for 3 secs. to allow access to RDU

Upgrade function

SD card + RDU + RDU Cable

Firmware loader process checks for file RDUFW.bin on SD card and, if found, asks the user for confirmation before upgrade.

NOTE: v2.09 firmware contains identical features to v2.08, but fixes several bugs:

1) Intermittent FAIL to save RDU configuration settings

2) Peak RPM not accurate if user enters RDU setup while motor test in progress

3) If atmospheric pressure abnormally low at RDU power ON time, HEIGHT data corrupted

EM2-RDU Sample Rate vs. Storage Time

Sample Rate StorageTime hh:mm:ss

4 samples/sec 00: 20: 50

2 samples/sec 00: 41: 40

1 samples/sec 01: 23: 20

2 seconds/sample 02: 46: 40

4 seconds/sample 05: 33: 20

8 seconds/sample 11: 06: 40

On connection to Emeter II, RDU will upload

saved logs to Emeter and clear RDU memory

2 samples/sec is default setting

*Note that the max currents listed above are highly dependant on ambient air temperature, and especially the amount of

cooling airflow that passes through the RDU. On a cold day with good airflow, you may increase Continuous and 30-sec Max

amperages by some percentage, or reduce for hot days and poor airflow. Currents above 150A require user modification to

increase input/output wire size, and appropriate connectors. The “bottom line” is that it is your responsibility to check

temperatures to insure the RDU is not heat damaged (75C max). RDU unit returned with clear evidence of over-current heat

damage will NOT be covered by warranty replacement policy.

Also see http://media.hyperion.hk/dn/em2 (bottom of page) for the “Emeter II Suite” PC Software, which allows direct

programming of RDU parameters, log file downloads from SD Card or direct from the RDU, and “live” bench testing with RDU

connected to PC. The Suite also contains graphing functions, and will soon support other features such as test profile

creation for upload to the Emeter.

WARRANTY

- Emeter and RDU are guaranteed to be free from defects in materials and workmanship for a period of one calendar year

from date of purchase.

- Damage due physical shock (dropping on the floor, etc), inappropriate power supply (battery charger, etc!), water,

moisture, over-voltage or over-current operation, and humidity are specifically NOT covered by warranty.

- Your selling dealer is your first point of contact for warranty issues.

- Return postage costs are the responsibility of the user in all cases. Submit copy of original receipt with the return.

- Returned units should be examined by the Hyperion dealer’s tech department within 1 week of arrival, maximum, and

contact made with the user to explain the findings.

REPAIR/REPLACEMENT DUE TO NON-WARRANTY ISSUES:

Due to the nature of the miniature electronics employed, and high cost of hand labor and shipping involved, it is not

economically feasible to repair electronics in many cases. Instead, we offer a blanket exchange policy at 55% of the US$

original suggested retail price (plus any taxes due in your area, and return shipping). In the event that your Emeter/RDU is

user damaged and warranty will not apply, please contact your selling dealer to obtain the correct return shipping address,

for exchange under this program.
