Press the
〈
OK
〉
button to begin the standard count. After taking the
standard count, the gauge software displays the results, as shown in
Figure 4–3.
Troxler recommends that the operator keep a daily log of the
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% each day for DS1 (density standard),
±
1.3% each day for DS2 (density standard), and
±
2% each day for MS (moisture standard).
If the standard count passes , record the standard counts, then
press the
〈
Yes
〉
button. The PDA displays the prompt Do you
wish to erase the last four standard counts? Press
〈

〉
. The PDA displays
Standard counts have been
stored.
Press the

If the standard count fails by less than 10% and it has been more
than a month since the last standard count, then accept the
standard count by pressing the
〈

button. At the
Do you

prompt,
press the
〈
Yes
〉
button. The PDA displays Standard counts
have been stored. Previous four standard counts were
erased from memory.
Press the
〈
ok
〉
button to return to the Standard Menu . Take
four additional standard counts. The last of these counts will be
compared to the previous four, and the standard counts should
pass. If not, repeat the procedure. If it still fails, perform a stat
test (see page C–2) and a drift test (see page C–5), then contact
your Troxler representative.
