& magnetic base, full set.
* Metric & Imperial display unit.
* Acceleration, Velocity measurement.
* RMS, Max hold , Peak value measurement.
* Max. Hold reset button, Zero button.
* Wide frequency range.
* Data hold button to freeze the desired reading.
* Memory function to record maximum and minimum
reading with recall.
* Separate vibration probe with magnetic base, easy operation.
* Real time SD memory card Datalogger, it Built-in Clock
And Calendar,real time data recorder, sampling time set

* Innovation and easy operation, computer is not need
to setup extra software, after execute datalogger, just
take away the SD card from the meter and plug in the
SD card into the computer, it can down load the all the
measured value with the time information(
year/month/date/hour/minute/second) to the Excel
directly, then user can make the further data or graphic
analysis by themselves.
* SD card capacity : 1 GB to 16 GB.

4. MEASURING PROCEDURE
1) Power supply installation :
* The meter's power supply should install the batteries
and connect " AC to DC adapter " together.
* The batteries are the power of " Clock ".
Batteries
Install the batteries into the battery compartment :
* Loose the " Screw of the battery cover " ( 3-13, Fig. 1 )
and take away the " Battery Cover " ( 3-12, Fig. 1 ) from
the meter.
* Replace with DC 1.5 V battery ( UM4/AAA, Alkaline/Heavy
duty type ) x 6 PCs, and reinstate the cover.
* Make sure the battery cover is secured after changing
the battery.
AC to DC adapter
* The " AC to DC adapter " is the standard accessory.
* Plug the output plug of " AC to DC adapter " into
the " DC 9V power adapter input socket " ( 3-9, Fig. 1 )
2) Vibration Sensor
Connect the vibration pickup to the cable supplied
Make sure it is firmly attached. Connect the cable
to the meter by attaching it to the "BNC connector( 3-8, Fig. 1 )
on the Bottom of the meter.If the surface to be tested is magnetic,
attach the magnetic base to the vibration pickup and attach the
pickup to a flat surface.If the surface to be tested is not magnetic,
hold the pickup against the surface. Do not hold the cable while
making measurements.

3) Vibration unit
The currently selected unit of measure is shown on the
meter’s LCD. To change the unit of measure, press and hold
the ▲ Button " Unit Button ( 3-3, Fig. 1 )" until the desired unit
of measure appears and then release the button.
if want change metric or imperial please refer chapter 7-7 (page 18 ).
4) Function Selection
The currently selected function is shown on the meter’s
LCD. To change the function, press and hold the button.
"FUNCTION button( 3-6, Fig. 1 )" until the desired function
appears, then release the FUNCTION .
The available functions are:
RMS: Typical selection for Acceleration and Velocity
PEAK: Displays the peak value of the vibration
MAX HOLD: Displays and holds the max value measured
MAX HOLD Reset:
Press and hold the ▲ and ▼ buttons for > 3 seconds to clear the
Max. Hold reading.

5) Data Hold:
To freeze a displayed reading on the LCD, momentarily press
the"HOLD button ( 3-4, Fig. 1 )" (the HOLD icon will appear
above the reading). To exit HOLD, press the HOLD button again.
6) ZERO Adjustment
The ZERO function is used to remove any small offset caused
by temperature changes or other environmental changes.
The zero will only work for a display of 10 or less digits.
1. Connect the vibration sensor to the meter
2. Set the measurement function to Acceleration
3. Make sure the sensor is motionless and not subject to
any vibrations.
4. Press and Hold the ▼ and ▲buttons for 3 seconds and the
meter will show zero .
7) REC ( Record):
For a given measurement session, this meter can record the
highest (MAX) and the lowest (MIN) readings for later recall.
1. Press the REC button momentarily to access this mode
of operation (REC icon appears)
2. The meter is now recording the MAX and MIN readings.
3. Press the REC button again to view the current
MAX readings (MAX icon appears). The readings on the
display are now the highest readings encountered since
the REC icon wasswitched on (when the MAX-MIN button
was first pressed).
4. Press the REC button again to view the current MIN
readings (MIN icon appears). The readings on the display
are now the lowest readings encountered since the REC icon
was switched on (when the REC button was first pressed).
5. To exit the MAX-MIN mode, press and hold the REC
button for 3 seconds. The meter will beep, the REC-MAX-MIN
icons will switch off, the MAX-MIN memory will clear,
and the meter will return to the normal operating mode.
