use.
Powering the meter
Open the battery compartment by loosening the two screws located on the back of the meter
(on either side of the magnet). Insert a new CR2032 3V lithium button battery and close the
cover. If a battery is already installed, remove the insulation strip so that the battery can make
proper circuit contact.
The instrument is now ready for use. Press the ON/OFF key once to power the meter. The
meter's previous settings will be preserved.
All EU users are legally bound by the battery ordinance to return all used batteries to collection
