Zero Adjustment Procedures - Lutron Electronics VB-8206SD Operation Manual

3. Peak measurement is intend to measure the peak
vibration value.
The Display will show the indicator " PEAK ".
4. After select the unit will be saved into the circuit with
default.
5. Acceleration and Velocity measurement can select 3
function : RMS, PEAK, MAX HOLD
* Typically, for Acceleration and Velocity measurement
always select to the " RMS " measurement.
6. Displayment measurement can select 2 function :
" DISP p-p " or MAX HOLD ( DISP p-p )
* Typically, for Displacement measurement
always select to the " DISP p-p " measurement.

4-4 Zero adjustment procedures

Due to drift of environment temperature value, battery
power change, 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) Vibration sensor is ready, connect the " Plug of cable "
( 3-21, Fig. 1 ) into the " " Input socket " ( 3-7, Fig. 1 ).
2) Select the measurement to the " Acceleration "
3) Keep the vibration sensor motionless, no signal into
the vibration sensor.
4) Press the " LOGGER Button " ( 3-6, Fig. 1 ) continuously
at least 5 seconds will let the display reach zero value.
5) The zero adjustment can be execute only
the display value show the no. less than 10 digits.
