GAUGE READINGS APPEAR ERRATIC
✓ Check the count time – A 4-minute count will give highest
precision with a repeatability of ± 1 pcf (± 16 kg/m
3
).
✓ Perform 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 your nearest Troxler Service Center (see
page C-17).
GAUGE WILL NOT COMMUNICATE WITH PRINTER OR
COMPUTER
✓ Check the cable for continuity.
✓ Ensure that the correct cable is in use.
✓ Make sure the gauge and printer/computer baud rates are the
same (see page 6–10).
✓ Make sure all other parameters match:
♦ Data bits = 8
♦ Stop bits = 2
♦ Parity = none
♦ Protocol = DSR/DTR
GARBAGE OR XXXXXX IS DISPLAYED
✓ Check the standard counts in memory.
✓ Check gauge for water damage – dry gauge interior with hair
dryer on low heat) for 3 hours.
✓ Perform new standard counts. If counts = 0 for both systems,
replace high voltage module (contact your nearest Troxler
Service Center, see page C-17).
✓ Check calibration constants against the factory calibration sheet.
