Figure 1. Operation
Note
The Relative or Zero function on your DMM (if available) can
be used instead of the ZERO potentiometer to zero the meter.
Refer to the multimeter's user manual for instructions on using
this function. Zeroing the meter does not affect the module's
specified accuracy.
6.
Apply pressure/vacuum to the PV350 and read the DMM display.
•
When measuring pressure, if the DMM displays OL,
switch the multimeter range from millivolts to dc volts.
Increasing the range to dc volts moves the decimal
position three places to the left (500 psi displays as
0.500 V).
•
When measuring vacuum the DMM displays a minus sign.
Testing the Battery
1.
Turn the DMM and the module OFF and connect the PV350 to the
DMM.
2.
Turn the DMM on and set the DMM to the mV dc range.
3.
If the DMM displays less than 100 mV, replace the battery.
How to Replace the Battery
Warning
To avoid electrical shock, disconnect the module from all
devices before opening the case. Be sure to completely
reassemble the module before attempting to use it.
