Step
1 Measure voltage between terminal 5
and 6.
2 Measure nipple voltage between
terminal 5 and 6.
3 Measure sensor excitation voltage
between terminal 7 and 10.
4 Measure sensor excitation voltage
between terminal 8 and 9.
5 Measure current in supply lead to
terminal 5.
6 Measure current in supply lead to
terminal 6.
7 Measure sensor resistance with sensor
cable unconnected between:
Terminal 7 to cable shield.
Terminal 8 to cable shield.
Terminal 9 to cable shield.
Terminal 10 to cable shield.

Limits
Voltage should be in the range 17 to 22 V
DC. Check power supply.
Voltage must not exceed 2 V AC.
Check power supply.
Voltage should be in the range 3.0 and
6.2 V DC.
Voltage should be in the range -15 to 100
mV DC.
Current should be in the range 4 to 20
mA and the same value as measured in
point 6. if not the amplifier may be
defect.
Current should be in the range 4 to 20
mA and the same value as measured in
point 5. if not the amplifier may be
defect.
If the measured resistance is less than 1
M Ohm the sensor is considered defect.
