3. False alarms
 Add some time delay to unit.
 If coax cable is used from sensors to pulse
card (PMC 2000), make sure it is not coiled
(may cause an increase in inductance).
 Make sure there is no outside interference that
may be causing false alarms such as an
agitator, high voltage interference, or input flow
to the tank affecting the probe.
 Adjust the sensitivity switch to next setting to
decrease the 9830’s sensitivity. Test sensor
after the setting has been increased to make
sure the sensor can still reliably sense the
presence of liquid.
 Make sure separator or grease trap is filled up
with water above the white Teflon (sensing
area) of probe.
