Adjustment count
The adjustment count feature provides an independent "serialization" of
your adjustments. With it, you can determine the number of times your
instrument has been adjusted. By monitoring the adjustment count, you
can tell whether an unauthorized adjustment has been performed. The
value increments by one each time instrument is adjusted.
The adjustment count is stored in a non- volatile EEPROM memory, the
contents of which do not change even after the instrument is switched off.
Your clamp meter had been adjusted before leaving the factory. When you
receive your clamp meter, make sure to read the adjustment count for the
first time and record it for maintenance purpose.
The adjustment count increases up to a maximum of 9999, after which it
wraps around to 0. There is no way to program or reset the adjustment
count. It is an independent electronic "serialization" value.
To view the present adjustment count, unsecure the instrument (see
"Unsecuring the instrument for calibration"
on page 98), and then press
Shift/Peak for more than 1 second to view the adjustment count. Press
Shift/Peak for more than 1 second again to exit the adjustment count
display.
