6. سار سنڀال

6.1 صفائي

ميٽر جي ڪيس کي اشتهار سان صاف ڪريوamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is powered off and disconnected from any circuits before cleaning.

6.2 بيٽري مٽائڻ

Refer to Section 4.1 for battery installation instructions. Replace the 9V battery when the low battery indicator appears on the display.

6.3 فيوز مٽائڻ

If the current measurement function fails, the fuse may need replacement.

1. Ensure the multimeter is powered off and all test leads are disconnected.
2. Open the battery compartment cover as described in Section 4.1.
3. Locate the fuse(s) inside the compartment. The OW18B typically uses two fuses: a fast-acting 600mA/250V fuse for the mA range and a fast-acting 20A/250V fuse for the 20A range.
4. Carefully remove the blown fuse and replace it with a fuse of the exact same type and rating.
