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.
8 Measure sensor bridge resistance with sen-
sor cable unconnected between:
Terminal 7 to terminal 8.
Terminal 7 to terminal 9.
Terminal 7 to terminal 10.
Terminal 8 to terminal 9.
Terminal 8 to terminal 10.
Terminal 9 to terminal 10.
9 Visual inspect the transmitter for:
- Damages on the cable
- Sharp bends on the cable
- Moisture/liquids in the breather tube
- Damages on the diaphragm

Unit Limits
V DC Voltage should be in the range 17 to 22 V DC.
Check power supply.
V AC Voltage must not exceed 2 V AC.
Check power supply.
V DC Voltage should be in the range 3.0 and 6.2 V
DC.
mV DC Voltage should be in the range -15 to 100 mV
DC.
mA 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.
mA DC 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.
