OPERATING &
MAINTENANCE TIPS
When the
icon appears at the upper left of the
LCD, it’s time to replace the three “AAA” batteries that
power the meter (although measurements will remain
valid for several hours after the icon first appears). To
replace the battery, follow the instructions on p. 10.
Do not operate the CM660/700 in the presence of
flammable or explosive gas or near an arc welder or
induction heater.
After subjecting the meter to a large change in
ambient temperature, wait at least 30 minutes before
making measurements to guarantee the accuracy of
readings.
Remove the batteries when storing the meter or when
you do not expect to use it for an extended period of
time (months rather than weeks).
Do not disassemble the CM660/700 or immerse it in
water.
