TROUBLESHOOTING | RJG, INC. SENSOR PRECHECK 30
STRAIN GAGE SENSORS
COMMUNICATION FAILURE
The Sensor PreCheck lost connection to the sensor
electronics:
• Replace the Lynx cable and try again.
• If a new cable does not correct the issue, the problem
is most likely the sensor electronics.
• If the test fails again, replace the strain gage adapter
(SG/LX….) and retest.
• If the test fails again, request an RMA for return from
RJG.
GAGE/WIRE TEST FAILURE
There may be a broken wire:
• Perform a visual inspection of the sensor cable.
• If cable is okay the gage may be damaged or
overloaded.
• Remove the sensor form the tool and retest the sensor.
If the sensor now passes the test, check the sensor
pocket installation dimensions.
• If the sensor fails again, request an RMA for return from
RJG.
ZERO SHIFT FAILURE
Remove sensor from tool and retest. Failure could be
caused by preload due to installation. Common causes
of preload are:
• Radius in the corners of the sensor pocket.
• Improper sensor pocket depth.
• Not enough clearance above the ejector pin head.
If the sensor fails after removal from the tool, the sensor
needs to be re‑calibrated or replaced.
• Request an RMA from RJG.
FORCE TEST FAILURE
Tester did not detect any force being applied;
• apply pressure on pin or directly on sensor head.
• Remove the sensor from the tool and retest the sensor.
If the sensor passes, check that the pin moves freely.
The pin should slide forward and backward easily. The
pin should also spin easily.
• If the sensor fails again, request an RMA from RJG.
