Model 3430 Plus & 3440 Plus
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 (see page 5–5):
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 (9600 baud).
✓
Ensure that all other parameters match:
♦
Data bits = 8
♦
Stop bits = 1
♦
Parity = none
