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.
GARBAGE OR XXXXXX 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 Troxler
Technical Support (see page B–11).
Check gauge for water damage. If the gauge is wet, dry the
gauge interior with hairdryer (on low heat) for 3 hours.
Check the calibration constants. They should match the
constants on your calibration data sheet if your calibration
sheet is in metric units. (Refer to the note on page 1–5 to
determine if your calibration sheet is in metric units and, if not,
for instructions on converting B and F values from English to
metric units.)
If necessary, perform a statistical stability (stat) test (see page
4–2), record the results and contact Troxler Technical Support
(see page B–11).
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 3.0 volts, recharge or replace the
batteries.
The scaler may be defective. To test, replace the suspect scaler
with a good scaler.
