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 four-minute count will give the highest
precision, with a repeatability of ±1 pcf on repeated tests
performed without moving the gauge.
✓
Erratic density readings may be caused by a dirty tungsten
sliding block. Clean the sliding block (see page A–11).
✓
Perform a stat test:
► If test passes, proceed with job.
► If test fails, repeat two more times. If test fails two out of
three times, contact the nearest Troxler Service Center.
GAUGE WILL NOT COMMUNICATE WITH PRINTER OR
COMPUTER
✓
Check that the correct cable is being used.
✓
Ensure that the gauge and printer/computer baud rates are the
same (see page 3–13).
✓
Ensure that all other parameters match:
♦
Data bits = 8
♦
Stop bits = 2
♦
Parity = none
♦
Protocol = DSR/DTR
