BATTERY REPLACEMENT

The instrument is powered by a 9V battery located at the back of the

instrument.

When the battery is rundown, the Battery Error Preventive System

(BEPS) circuitry is activated. BEPS shuts down the LCD automatically

to ensure that no erroneous readings are taken due to a weak

battery. In such cases, the battery needs to be replaced for the correct

functioning of the instrument.

To access the battery, remove the battery

cover by applying pressure in the direction

indicated. Unplug the rundown battery

and replace it with a new one. Re-insert

the battery and replace the cover.

Battery replacement must only take place

in a non-hazardous area using a 9V alka-

line battery.
