F. MAINTENANCE
GAUGE READINGS APPEAR ERRATIC
If taking readings in the backscatter position, ensure the source rod is
properly locked in the notch and not resting on the test material.
Check the inside of the gauge for moisture. To dry the gauge interior,
remove the keypad. If necessary, use a hair dryer (on low heat) to
circulate warm air for one to three hours.
Remove any foreign objects from inside the gauge.
Ensure the hardware mounting screws are tight and in place.
Check count time – A 4-minute count will give the best precision with
a repeatability of ± 1 pcf.
Erratic density readings may be caused by a dirty sliding block. Clean
the sliding block.
Perform a statistical stability (stat) test. If test passes, proceed with
job. If test fails, repeat two more times. If test fails two out of three
times, contact Troxler Service.
