Troubleshooting the NT
®
Pressure
Transducers may be accomplished
by measuring the output signal of
the pressure transducer with a
battery powered current/voltage
meter. The meter may be placed in
series with the pressure transducer
to measure the current output or it
may be used to directly measure the
voltage output.
Using the battery powered current/
volt meter is an effective method to
determine whether the device or the
on-site data acquisition system is not
functioning properly.
