Appendix A–4
Perform a statistical stability (stat) test.
f If test passes, proceed with job.
f If test fails, repeat two more times. If test fails two out of
three times, contact the nearest Troxler Service Center.
NOTE
To aid in verifying gauge readings, after a gauge has
been calibrated, mark a test area on a concrete floor,
sidewalk, or equivalent and measure the density
(WD). This measurement can then be used as a
reference to verify later gauge readings.
Unreadable, XXXX or ++++ is Displayed
Check the standard counts in memory. If the standard
counts are suspect, perform new standard counts. If counts
equal zero for both systems, replace high voltage board.
Contact the nearest Troxler Service.
Ensure that the measurement depth (depth of the source
rod handle) is the same as the depth displayed on the
display before starting a measurement.
Check gauge for water damage. If the gauge is wet, dry the
gauge interior with hairdryer (on low heat) for 15 minutes
to 1 hour.
Check that the calibration constants are valid.
If necessary, perform a statistical stability (stat) test, record
the results and contact the nearest Troxler Service Center.
Gauge Turns off after it is Turned On
The gauge automatically turns off after five hours if no keys
are pressed. Try to turn the gauge on again.
The gauge may be wet. Do not turn the gauge on until
moisture is removed from gauge interior! Component
damage may result.
If the battery is below 5.5 volts, recharge or replace the
batteries.
