Vzdrževanje

Čiščenje

Za čiščenje multimetra obrišite ohišje zamp cloth and a mild detergent. Do not use abrasives or solvents, as these may damage the casing ali zaslon.

Zamenjava baterije

When the low battery indicator appears on the display, replace the 9V battery as described in the "Installing the Battery" section to ensure continued accurate readings.

Zamenjava varovalke

If the current measurement function stops working, the fuse may need replacement. This multimeter is equipped with internal fuses for protection.

2. Odstranite pokrov baterije in baterijo.
3. Carefully open the main casing (this may require removing additional screws, typically located under the rubber shell).
4. Locate the fuse(s) on the circuit board. This model typically uses a 200mA/250V fuse for the mA range and a 10A/250V fuse for the 10A range.
5. Replace the blown fuse with a fuse of the same type and rating. Never use a fuse with a different rating.
6. Reassemble the multimeter, ensuring all screws are tightened and the casing is properly sealed.

Shranjevanje

If the multimeter is not used for a long period, remove the battery to prevent leakage and store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
