Combustilbe Gas Transmitter • 10
Performing the response test
1. Screw the regulator into the calibration cylinder.
2. When the reading on the voltmeter stabilizes after approximately 2 minutes, verify
that the reading is within ± 10% of the response reading you determined earlier.
NOTE: If the reading is not within ± 10% of the correct response reading, calibrate the
transmitter as described in the Calibration section of this insert.
3. Unscrew the regulator from the calibration cylinder, then disassemble the calibration
kit as described in the Calibration section of this insert.
Quarterly
Calibrate the combustible gas transmitter as described in the Calibration section of this
insert.
Troubleshooting
The troubleshooting guide describes symptoms, probable causes, and recommended
action for problems you may encounter with the combustible gas transmitter.
NOTE: This troubleshooting guide describes transmitter problems only. See the
controller instruction manual if it exhibits any problems.
Fail Condition
Symptoms
• The controller is indicating a reading well below zero.
• The controller is indicating a fail condition.
Probable causes
• The transmitter wiring is disconnected or misconnected.
• The transmitter is malfunctioning.
Recommended action
1. Verify that the transmitter wiring is correct and secure. The Installation section of this
insert describes transmitter wiring connections.
2. Calibrate the transmitter as described in the Calibration section of this insert.
3. If the fail condition continues, replace the detector as described later in this section.
4. If the fail condition continues, contact RKI Instruments, Inc., for further instruction.
Slow or No Response/Difficult or Unable to Calibrate
Symptoms
• The transmitter responds slowly or does not respond during the monthly response
test.
• Unable to accurately set the zero or response reading during the calibration
procedure.
• The transmitter requires frequent calibration.
