Troxler recommends that the operator keep a daily log of the
moisture and density standard counts (see Appendix E). To verify
gauge stability, compare the daily standard count to a reliable
reference as follows:
♦
During the first four days of operation of a new or recalibrated
gauge, compare the daily standard count to the factory-
calibrated values.
♦
After the first four days of operation (or after taking four
standard counts), compare the daily standard count to the
average of the last four counts. Acceptable standard count limits
are:
±1.3% each day for DS1 and DS2 (density standards) and
±1% each day for MS (moisture standard).
► If the standard count passes, record the standard counts, then
press the
〈YES〉 key. The gauge displays:
The gauge calibrates the index rod depth strip and returns to the
Ready display.
► If the standard count fails and it has been more than a month
since the last standard count, then accept the standard count by
pressing the
〈YES〉 key. At the Do You Want To Erase Last
Four Standard Counts? prompt, press the
〈YES〉 key. The
gauge displays:
