The unit can be selected as :
Measurement Metric unit Imperial unit
Acceleration , G
Velocity mm/s, cm/s inch/s
Displacement mm inch
Remarks :
For general applications of industrial vibration
monitoring, select " Velocity " or " Acceleration "
typically.
How to change the Metric unit to Imperial
unit each other
If press the " UNIT Button" ( 3-6, Fig. 1 )
continuously at least 5 seconds, then will
change the Metric unit ( , G, mm/s, cm/s, mm ) to
Imperial unit ( , inch/s, inch ) each other.
6)Data Hold :

and REC icons ON) cycling. Momentarily pressing
" HOLD Button " ( 3-3, Fig, 1 ) to leave Max/Min mode
and execute the RECORD function continuously.
5. ZERO ADJUSTMENT PROCEDURE
Due to drift of environment temperature value, battery
power change or, meter used for a long time or other
reasons. The display value may exist not zero value ( few
digits ) in case of no signal into the " Vibration Sensor ".
General speaking those not zero value will not effect the
measurement typically. However if intend to make the
precision measurement, the following zero adjustment
procedures should be executed as :
1)Plug in the " BNC plug of cable " ( 3-10, Fig. 2 ) to the
" BNC socket of meter " ( 3-9, Fig. 2 ).
2)Plug in the " Mini plug of cable " ( 3-11, Fig. 1 )

3)Power on the meter by press the " Power Button "
( 3-2, Fig. 1 ) once a while.
11

4)Set the function and the unit to " ACC, RMS " .
5)Keep the vibration sensor motionless, no signal into
the vibration sensor.
6)Press the " HOLD Button " ( 3-3, Fig. 1 ) continuously
at least 2 seconds will let the display reach
zero value.
7)The zero adjustment can be execute only
the display value show the no. less than 10 digits.
6. POWER MANAGEMEN
T
The meter is built the " Auto power shut off " to saves
battery life. If not any function button be pushed within
approx. 10 minutes, the power will be off automatically.
If the user intend to disable the " Auto Power off "
function, it should take the following procedures :
During the measurement, push the " Record
Button " ( 3-4, Fig. 1 ) to execute the memory
record function.
7. Data Logger
The data logger function can save max. 500 measuring
data.
The data logger procedures are as following :
12

Auto data logger
If the data sampling time already set to
1, 2, 10, 30, 60, 600, 1800 or 3600 second,
then the meter can be executed the auto data logger
function. The procedures that to set the data logger
sampling time, please refer page 14.
1.Press the " REC Button " ( 3-4, Fig. 1 ) once to
start the Data Record function and there will be a
" REC " symbol on the display.
2.Press the " LOGGER Button " ( 3-6, Fig. 1 ) once to start
the Auto Data Logger function. The upper display will
show the sampling time in seconds ( For example, 1, 2,
10, 30, 60, 600, 1800, 3600 ) once a while then revert
to the normal display screen. In the same the " REC "
indicator will be flash per the sampling time, in the
same time, the beeper will sound a while.
Now the data Logger function is executed and the
measuring data will save into the memory per
the sampling time.
3.During the Data Logger function is executed, press the
" LOGGER Button " ( 3-6, Fig. 1 ) once will stop to
execute the data logger function, then the " REC "
indicator will stop to flash.
Pressing the " REC Button " ( 3-4, Fig. 1 ) at least
two seconds, then the " REC " indicator will be
disaapeared.
13

Manual data logger
If the data sampling time already set to 0 second,
then the meter can be executed the manual data logger
function. The procedures that to set the data logger
sampling time, please refer page 14.
1.Press the " REC Button " ( 3-4, Fig. 1 ) once to
start the Data Record function and there will be a
" REC " symbol on the display.
2.Press the " LOGGER Button " ( 3-6, Fig. 1 ) once to start the
Manual Data Logger function. The upper display will
show " 0 " ( 0 second sampling time ) once a while then
revert to the normal display screen.
Press the " LOGGER Button " ( 3-6, Fig. 1 ) once again
will save one measuring data into the memory,
indicator will be flash per the sampling time, in the
same time, the beeper will sound a while.
3.If intend exit the Manual Data Logger function, just
pressing the " REC Button " ( 3-4, Fig. 1 ) at least
two seconds, then the " REC " indicator will be
disaapeared.
Change the data logger sampling time
1.Power off the meter.
2.Use the two fingers to press the " HOLD Button " ( 3-3,
Fig, 1 ) and the " REC Button " ( 3-4, Fig. 1 ) at the same
time and not release those fingers, use another finger
to push the " POWER Button " ( 3-2, Fig, 1 ) once, then
until the display show the existing sampling time ( for
example 1, 2...), then release the two fingers at the
same time.
14

3.Press the " UNIT Button " ( 3-6, Fig. 1 ) once a while
will change the sampling time ( 1, 2, 5, 10, 30, 60,
600, 1800, 3600 seconds ). After the desired sampling
be selected, then press the " REC Button " ( 3-4, Fig. 1 )
to save.
4 Press the " ESC Button " ( 3-3, Fig. 1 ) once will return
the normal measuring screen.
Clear the memory ( clear the existing save data )
1.Power off the meter.
2.Use the two fingers to press the " HOLD Button " ( 3-3,
Fig, 1 ) and the " REC Button " ( 3-4, Fig. 1 ) at the same
time and not release those fingers, use another finger
to push the " POWER Button " ( 3-2, Fig, 1 ) once, then
until the display show the existing sampling time ( for
example 1, 2...), then release the two fingers at the
same time.
3.Press the " REC Button " ( 3-4, Fig. 1 ) continuously
at least 5 seconds, then display will show " 0 ".
Now the memory already be cleared.
Check the existing data that save into the memory
1.Power off the meter.
2.Use the two fingers to press the " HOLD Button " ( 3-3,
Fig, 1 ) and the " REC Button " ( 3-4, Fig. 1 ) at the same
time and not release those fingers, use another finger

example 1, 2...), then release the two fingers at the
same time.
15

3.Press the " HOLD Button " ( 3-3, Fig, 1 ) or the
FUNCTION Button " ( 3-5, Fig. 1 ) will search the
the data that already save into the memory.
* " HOLD Button " - Increase the data no.
* " FUNCTION Button " - Decrease the data no.
Memory full
During execute the data logger function, if the meter's
Beeper generate the " Long beeper sound along a short
stop " continuously. It means that the Memory is full.
8. HOW TO SEND THE DATA OUT
FROM the METER
If intend to send the data out from the meter, it should
cancel the " Hold function " and the " Record function "
first. The display will not show the " HOLD " and the "
REC " marker.
1)Press the " Send Button " ( 3-5, Fig. 1 ) at least 2
seconds until the display show " 232 " ( flashing ),
release the button.
2)Push the " Send Button " ( 3-5, Fig. 1 ) once again,
the display will show the saved data no, then decrease
to " 1 " and the display will present " 232 " again, now
all the memory data already send out from the meter
via the " RS-232 Output Terminal " ( 3-8, Fig. 2 ).
3)If intend up load the data to the computer, then should
connect the RS232 cable ( optional, model : UPCB-02)
or USB cabke ( optional, model : USB-01 ) and apply
the Data Logger software ( optional, Model : DL-2005 ).
