Data Record ( Max., Min. reading )
The DATA RECORD function displays the maximum, minimum readings for the measurement of:
Acceleration ( RMS ), Velocity ( RMS ) and Displacement ( p-p )
1. Press the " REC button " ( 3-4, Fig. 1 ) once to start the Data Record function. " REC " will
be displayed.
2. With the " REC " symbol on the display :
a) Press the " REC button " ( 3-4, Fig. 1 ) once, the "REC MAX. " symbol along with the
maximum value will appear on the display.
To delete the maximum value, just press the " Hold button " ( 3-3, Fig. 1 ) once. The display
will show " REC " and execute the memory function continuously.
b)Press the " REC button" ( 3-4, Fig. 1 ) again, the REC MIN. " symbol along with the
minimum value will appear on the display. To delete the minimum value, just press the"
Hold button" ( 3-3, Fig. 1 ) once, then the display will show the " REC " symbol only and
execute the memory function continuously.
c) To exit the memory record function, just press the " REC button " for at least 2 seconds.
The display will revert to the current reading.
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. Press the " Function buttion " ( 3-5, Fig. 1 ) to the " Acceleration " position.
2. No signal into the vibration sensor.
3. Press the " Zero button " ( 3-3, Fig. 1 ) continuously at least 2 second, the display will return
to zero value with default.
Data Logger
The data logger function can save 1000-point data for the vibration function.
The data logger procedures are as following :
a) 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.
b) Auto Data Logger ( Sampling time can select to 1, 2, 10, 30, 60, 600, 1800, 3600 seconds)
Press the " Logger Button " ( 3-6, Fig. 1 ) once to start the Data Logger function. The " "
symbol is flashed per the sampling time and the data will be saved into the memory circuit.
Now the Date Logger function is executed.
Manual Data Logger ( Sampling time set to 0 second )
Press the "Logger Button" (3-6, Fig.1) once, save the data one time into the memory circuit.
At the same time the " " symbol will be
flashed.
Memory full:
During execute the data logger function, if the display show " FULL ", it indicate the memory
data already over 1000 no. and the memory is full.
c) During the Data Logger function is executed, press the " Logger button " ( 3-6, Fig. 1 ) once
will stop to execute the data logger function, the symbol " "will be disappeared. If press
the "Logger Button" (3-6, Fig.1) once again will continuous the Data Logger function.
Remark :
1)
If intend to change the data logger sampling time, please refer section
2)
If intend to know the space of balance data numbers into the memory IC, please refer
section page
3)
If intend to clear the saving data from the memory please refer section.
