BATTERY INSTALLATION
The meter is powered by 4 AA batteries or a DC adaptor. Install the batteries into the rear battery
compartment observing correct polarity. When an adaptor is used, the batteries will be disconnected
from the meter. The adaptor cannot be used as a battery charger. When the battery voltage drops
below the required level,
and “Lob” will appear on the display, a beeper sounds and readings
are no longer displayed. (Press any key but the
SET
to stop the beeps). Replace the batteries to
resume normal operation.
