KANE-ALERT-CO2

Monitor

with Temperature

Operating Instructions

This is a portable, handheld carbon dioxide (CO2)monitor using NDIR

technology to provide long term stability. It also measures ambient temperature.

The monitor also has the following features:

;Data logger stores 48 sets of CO2and temperature readings in the last 24

hours - one log every 30 minutes.

;Max/Min mode records the maximum and minimum concentrations of

CO2since the monitor was switched on.

;Alarm mode sounds at 1000 PPM (the ASHRAE limit) and can be turned

off.

;RCFS Mode recovers original factory settings after the monitor is

recalibrated.

(Display Features and Modes)

MODE FUNCTIONS

The monitor has several Modes which can be adjusted. In sequence these modes

are Alti Mode, Alarm Mode, Outside Mode, Cali Mode, Datalogger Mode,

MaxMin Mode and rcFS Mode.

ALTI

Compensates for changes in

atmospheric pressure due to

altitude or weather conditions.

ALARM

Alarms when CO2 concentration

exceeds 1000 ppm. Alarm

sounder can be switched on or

off.

OUTSIDE

Modifies the outside CO2

concentration. The factory

nominal setting is 400 ppm.

CALI

Allows trained service personnel

to recalibrate the sensor. Take

care using this function as errors

can be created.

DATALOGGER

Shows CO2and temperature

records over the last 24 hours.

Reading No. 1 is the most recent.

Reading No. 48 is the oldest.

MaxMin

Shows Max and Min CO2

readings since last being

switched on. These readings are

cleared every time the device is

switched off.

rcFS

Recovers the factory setting.

OPERATION INSTRUCTIONS

Power On

Press Power button (1) to turn on the monitor after placing 4 AA batteries

into the battery compartment (take care to observe correct polarity) or AC

adapter plug into the DC socket. CO2 readings will show after 15 seconds of

warm up.

WarmUp

This lasts approximately 1 min before WARMUP disappears; none of the

functions will respond during warm up.

Normal Operation

After warm up, the monitor stabilizes and displays CO2 readings on its Upper

Display which remain visible at all times.

Temp and Ventilation Rates (Lower Display)

Use the Up/Down button to scroll through Temperature and Ventilation

Modes.

When pressing the Up button, the lower display goes through the following

sequence:

Temp °C-> Temp°F-> Vent Rates lps-> Vent Rate cfm/p

*Note: lps refers to Litres Per Second Per Person;

cfm/p refers to Cubic Feet Per Minute Per Person

This function assumes that each person exhales 300 cc of CO2every minute

and calculates the rate of ventilation of external air required to achieve

equilibrium at the measured CO2level.

Adjusting Modes

1. ALTI Mode – Setting the altitude at which you are using the monitor

1.1. Press Mode until ALTI flashes

1.2. Press Mode to alter between m (meters) and ft (feet)

1.3. Press Up/Down to adjust the altitude (Step=100m/500ft)

1.4 Press Enter to save the setting or leave the ALTI Mode, return to

UserMode.

2. ALARM Mode – Switching On or Off the Audible Alarm

2.1. Press Mode until ALARM flashes

2.2. Press Enter until ALARM “speaker icon” flashes

Press Up/Down to turn the ALARM On or Off

2.3. Press Enter to save the setting and return to UserMode.

3. OUTSIDE Mode – Setting the outside level of CO2if known

**Note: Ventilation Rate

Ventilation rate represents how much air is introduced into the indoor space

from the outside. Low levels indicate low ventilation rates and potentially

poor air quality. High levels indicate excessive ventilation and potential

excessive energy usage. To obtain an accurate measurement, readings

should be taken 2~3 hours after occupancy has stabilized in a space or

at a peak in daily CO2concentrations.

In indoor air quality control, CO2 value is an indicator of ventilation rate.

400ppm (Parts Per Million) is the default CO2concentration outside

(according to ASHRAE: American Society of Heating, Refrigeration and

Air-conditioning Engineers).

3.1. Press Mode until OUTSIDE flashes

3.2. Press Enter until OUTSIDE, CO2and PPM flash

Press Up/Down to adjust the reading

3.3. Press Enter to save the setting and return to UserMode

After modification, the VENT Rate will change.

4. CALI Mode – Recalibrating the CO2sensor

4.1. The monitor is pre-calibrated in the factory and should only be

recalibrated with a certified test gas in a controlled test chamber. This

mode should only be accessed by trained service personnel.

5. DATA LOGGER Mode – Viewing data recorded over the previous 24

hours

The monitor’s internal Datalogger records CO2and temperature readings

every 30 minutes over the past 24 hours.

5.1. Press Mode until DATALOGGER flashes

5.2. Press Enter until CO2and Temperature are displayed

Press Up/Down to PAGE UP/DOWN readings

5.3. Press Enter to return to UserMode

6. MaxMin Mode – Viewing Maximum and Minimum values

The monitor’s MaxMin Mode displays the maximum and minimum CO2

readings since the monitor was last switched on.

6.1. Press Mode until MAX MIN flashes

6.2. Press Enter to alternate between MAX and MIN CO2readings

6.3. To clear the memory, press UP or DOWN until “CLR” flashes.

Press Enter to CLEAR the MAX and MIN record

6.4. Press Mode or Enter to return to UserMode

7. rcFSMode

If the CO2sensor is incorrectly re-calibrated, the monitor’s factory setting

can be recovered.

7.1. Press Mode until rcFS flashes on the lower display

7.2. Press Enter until “no” shows on the upper display

7.3. Press Up/Down to change to “yes”

Press Enter, Factory Setting will reload

7.4. Press Mode to return to UserMode

ELECTROMAGNETIC COMPATIBILITY

European Council Directive 89/336/EEC requires electronic equipment not to

generate electromagnetic disturbances exceeding defined levels and have

adequate immunity levels for normal operation. Specific standards applicable to

this analyser are stated below.

As there are electrical products in use pre-dating this Directive, they may emit

excess electromagnetic radiation levels and, occasionally, it may be appropriate

to check the analyser before use by:

Use the normal start up sequence in the location where the analyser will

be used.

Switch on all localized electrical equipment capable of causing

interference.

Check all readings are as expected. A level of disturbance is acceptable.

If not acceptable, adjust the analyser’s position to minimize interference

or switch off, if possible, the offending equipment during your test.

At the time of writing this manual (Nov 2007) Kane International Ltd are not

aware of any field based situation where such interference has occurred and this

advice is only given to satisfy the requirements of the Directive.

This product has been tested for

compliance with the following generic

standards:

EN 61000-6-3

EN 61000-6-1

and is certified to be compliant

Specification EC/EMC/KI/ALERT-CO2

details the specific test configuration,

performance and conditions of use.

Please Note:

Batteries used in this instrument should be disposed of in accordance with

current legislation and local guidelines.

At the end of the product's life it should be re-cycled in accordance with current

legislation and local guidelines.
