10. Inserting and replacing batteries
The multimeter is powered by three AAA batteries. Insert new batteries before using the multimeter for the first time
or when the low battery indicator appears on the display. Replace the batteries immediately to prevent inaccurate
measurements.
Never use the multimeter when the battery compartment is open, as this may cause a fatal electric
shock.
The multimeter casing is designed so that you can only access the battery compartment. This makes the multimeter
safer and easier to use.
a) Notes on batteries
• Do not leave empty batteries in the device. Even batteries protected against leaking may corrode and destroy the
device or release chemicals that are detrimental to your health.
• Do not leave batteries unattended, as there is a risk that they may be swallowed by children or pets. If a battery is
swallowed, seek immediate medical advice.
• To prevent the batteries from leaking, remove them from the multimeter if you are not going to use the device for
an extended period of time.
• Leaking or damaged batteries may cause acid burns if they come into contact with your skin. Always use protective
gloves when handling leaking or damaged batteries.
• Do not short-circuit batteries or throw them into open flames.
• Do not attempt to recharge or dismantle disposable batteries, as this may cause an explosion.
The following battery is suitable for use in the multimeter:
Order no. 652278 (3 batteries are required).
Only use alkaline batteries – alkaline batteries are more powerful and have a longer lifespan.
b) Inserting/changing the batteries
1. Switch the multimeter off by turning the control knob (16) into the < OFF > position.
2. Disconnect all test leads and remove the current clamp from all circuits.
3. Loosen the screw on the battery compartment cover (15) using a suitable screwdriver.
4. Remove the battery compartment cover.
- When removing the battery compartment cover, check the rubber seal for dirt and
clean it if necessary. This ensures that the multimeter remains dust- and splash-
proof.
5. 3 new AAA-size batteries are required. Remove the used batteries (if any) and
replace the used batteries with new ones of the same type. Insert the new batteries
into the battery compartment in the correct polarity.
- Do not use 1.2 V rechargeable batteries.
6. Replace the battery compartment cover and screw it in place.
7. The multimeter is now ready for use again.
