Figure 4–3. Standard Count Results

If the standard count fails and it has been less than a month
since the last standard count, but the count was performed
correctly and the
failure is less than 5% , press the
〈
Yes
〉
button.
If the failure is more than 5% , press the
〈
No
〉
button. Ensure
that the gauge is properly positioned on the reference standard
block (Figure 4–2). Verify that the standard count site meets the
criteria listed on page 4–2. Take another standard count and
accept it if it fails by less than 5%. If the standard count fails
four times, perform a stat test (see page C–2) and a drift test
(see page C–5), and then contact your Troxler representative.
After the standard count passes, the operator can take measurements
with the gauge. When not taking readings, always keep the source
rod in the
SAFE position. For added operator safety, the source rod
automatically retracts to the SAFE position when the gauge is lifted
using the handle.
