3.1.6 Troubleshooting Procedures
The chart below describes error messages that can appear
on the Sentinel II display.
Display Cause Solution
Open
probe
The capacitance being
measured by the unit is too
low. Possible causes include
missing probe; missing/broken
probe wire; or a poorly
connected probe wire.
Check the interconnection
wire between the probe
and the preamplifier.
Shorted
probe
Probe resistance between the
center connection and mount-
ing nut is less than 1 megohm.
Possible causes include a bare
probe in conductive media or
a damaged insulated probe in
a conductive media.
Check the probe resistance
by connecting an ohmmeter
between the center connec-
tion and the mounting nut.
If the resistance is less than
infinity, contact the factory.
Probe
error
Probe capacitance exceeds
50,000 pF.
Contact the factory for
application assistance.
No
return
signal
Occurs when the oscillator is
not receiving a signal. Possible
causes include a shorted
probe; missing/broken inter-
connection cable between
the preamplifier and the main
electronics (remote only); or
a defective circuit board.
If the probe is a shorted
probe, follow the instruc-
tions above for shorted
probe.
