2-6 Changing Batteries During Measurement
●
Please make sure the power is OFF when replacing batteries. If left ON, the meter
circuit could be damaged and measurements taken during the last operation will not be
saved.
●
If an unexpected display appears on the LCD during battery replacement or
measurement, ie. settings other than selected, or if the meter does not respond when
a button is pressed, remove the batteries, wait at least 10 seconds, and then re-install
them.
