Product Overview
The DIXON ADS capacitance sensor tester is designed to
verify function and calibration on a selection of DIXON ADS
brand liquid level sensors. The regular test and verification
of sensors ensures the ongoing safe, reliable, and
consistent operation for the life of the sensor. The
capacitance sensor tester and go-gauge verify the output
signals are within the factory accepted tolerances.

Compatibility
The capacitance sensor tester is designed to test the
output and trip point of A100 and A200 series sensors. It is
necessary for the A100 and A200 to be partly disassembled
before testing can be completed. The tester is limited to
only single point sensors.

2.Unplug the sensor connection at the bottom of the unit.
3.Connect this to the capacitance sensor tester.
4.Continue to Testing the Sensor section.
A200 Disassembly
1. Unscrew the housing lid.
2. Once open, disconnect the sensor from the
external plug and connect it the Sensor Output
Tester.

Testing the Sensor
1. Unscrew the thumb screw and knob all the way.
2. Place the capacitance sensor tip into the go-gauge,
then pull the sensor back until the shoulder is
captured.
3. Screw in the knob all the way.
4. Push the sensor towards the knob stem until the
sensor butts up against it.
5. Tighten the thumb screw to lock the sensor in
place.

6. Turn on the capacitance sensor tester.
7. Verify the capacitance sensor tester shows closed.
If the capacitance sensor tester shows any of the
following conditions, the sensor is considered bad:
a. Closed
b. No sensor
c. Shorted
Removed from service and contact Dixon technical
support.
8. Begin unscrewing the knob.
9. Verify the capacitance sensor tester switches from
closed to open before the knob is completely
unscrewed. Be sure to remove your hand from the
knob as this will interfere with the gauges
accuracy. If the knob is completely unscrewed and
the sensor output tester shows any of the
following conditions, the sensor is considered bad:
a. Closed
b. No sensor
c. Shorted
Remove from service and contact Dixon technical
support.

FAQ & Troubleshooting
•The capacitance sensor tester is not turning on.
oThe battery may be low. Try replacing the battery.
•The capacitance sensor tester shows red momentarily
while adjusting the trip window gauge.
oThis is normal behavior. The sensor and tester are
working properly.
•The capacitance sensor tester shows the sensor is
working correctly but the sensor doesn’t work when
assembled back into the A100/A200.
oThis may be an indication that the A100, or A210
repeater is bad. Call Dixon Technical service for further
troubleshooting.
•The sensor tester changes states when touching it with
my hand.
oThis is normal behavior. Your hand should be removed
while not adjusting the knob to prevent interfering
with the gauge’s capacitance.
