DRIFT TEST
If the stat test has already been performed (and has passed), but gauge
readings seem to be fluctuating from test to test, the Drift Test can be
performed to check the long-term drift of the 3440-L.
Pass and Fail limits are averages from the stat test and the difference in the
drift test average. If the average differences exceed 0.5% for density or 1%
for moisture, contact your Troxler service department.
Without turning off or moving the gauge
from the time the stat test was
taken, wait 3 to 8 hours and implement the drift test.
NOTE
The gauge should not be turned off between the stat and drift
tests. The stat test must be current. The gauge must not be
moved between the stat and drift tests to eliminate possible
failure due to positioning changes.
To execute the drift test, press 〈SHIFT〉 and 〈SPECIAL〉 for the display:
