8. Operation

a) Inserting the battery / Changing of battery

To operate the multitester two round cell batteries type 392A, AG3, LR41, 192 (or identically constructed) are needed.
To avoid an electric shock the multitester must not be operated when open. After each battery change a
self-test needs to be carried out.
To change the batteries you need to:
• Open the battery compartment at the end of the grip with a suitable screwdriver (3). Opening = turn left (anti-
clockwise). Also see illustration below.
• Take out the battery compartment lid (3). Carefully bend back the wire clip which holds the round cell batteries.
• Now take out the empty round cell batteries and replace them with two new others of the same type. Take care to
observe the polarity of the round cell batteries.
• Carefully bend back the wire in its original position.
• Put the screw back into the device. Carefully tighten the screw. Closing = turn right (clockwise).
Do not let batteries lie around openly. There is the risk of batteries being swallowed by children. In such
case, seek instant medical care. Do not let batteries lie around openly. There is the risk of batteries be-
ing swallowed by children. In such case, seek instant medical care. Leaking or damaged batteries might
cause acid burns when getting into contact with skin, therefore use suitable protective gloves. Never try to
recharge batteries. Do not throw batteries into fire.

b) Self-test

To avoid wrong readings, the operability of the multitester needs to be checked by a self-test before each use and
after each change of batteries. Please check the device for damage(s) such as e.g., breaks on the housing etc.
Touch the tip (1) of the tester with one hand and at the same time touch the battery
compartment lid (3) with the other hand.
When the red LED (2) starts blinking, the multitester is in working order and can be
used.
In case the red LED does not blink, the device must not be used. If necessary
change the batteries.
