Process of Troubleshooting
The 4C’s2:
1) Concern
2) Cause
3) Countermeasure
4) Confirmation

5. Typical Scenario involving Pressure Transmitter

6. 6 Copyright 2019 Baker Hughes Company. All rights reserved.
Troubleshooting – 1) Concern
Something happens:
• Alarm
• Intermittent Signal
• Faulty Reading
• Etc
Requires Investigation
Visit Location to determine
root cause

7. 7 Copyright 2019 Baker Hughes Company. All rights reserved.
Troubleshooting – 2) Cause
What to take?
1) Pressure Reference, e.g. a Digital Pressure Indicator or Gauge
2) Multimeter (with or without PS) & test leads
3) Power Supply (if not built into DMM)
4) Pressure Generation/Source, e.g. a Hand Pump
5) Adapters
6) Hoses
or

Calibrator!
Troubleshooting – 2) Cause
Note: still would require: test leads, adapters and hose(s)

• Isolate Transmitter from controls
• Power the transmitter with 24V soured and measure mA as part of a functional test or
calibration

• Check the loop and receiver by simulating transmitter signals. Use Step or Span Check for
quick linearity tests and Zero/Span adjustment
• For single handed loop tests use the Auto Step and Ramp outputs
Troubleshooting – 2) Cause – Step 2

Troubleshooting – 2) Countermeasure
Test/Check Cause Countermeasure
Failed Loop/Continuity Check (Step 1) Cut/Damaged Cable Replace/Repair
Failed Transmitter Check (Step 2) Failure – non-operational Replace/Repair
Failed Transmitter Check (Step 2) Failure – Xmitter out of spec If digital adjustment available, reset
Xmitter Zero and Span
Failed Transmitter Check (Step 2) Failure – Xmitter out of spec Measure Zero and Span setting and
make adjustment via Receiver input
Failed Receiver I/O Check (Step 3) Failure – bad I/O card Replace
None of the above? The dreaded intermittent failure/issue!
DPI610E can be used in Transmitter Simulation mode. Takes place of, or used in parallel with, the suspect unit.

20. A pressure calibrator does not care what it is testing…
• Any kind of mechanical or digital Pressure Gauge
• Pressure Switch/Vacuum Switch
• Pressure Sensors (of various outputs, mV, V, mA)
• Smart Transmitters
• Pressure based flowmeters
• I/P Converters
• Valves/Valve Actuators
• Leak Testing
• Others
