6. ساتنه

6.1. پاکول

قضیه د اعلان سره پاک کړئamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is off and disconnected from any circuits before cleaning.

6.2. د بیټرۍ بدلول

When the battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use fresh AAA batteries.

6.3. د فیوز بدلول

If the current measurement function stops working, the fuse may need replacement.

1. ډاډ ترلاسه کړئ چې ملټي میټر بند دی او ټول د ازموینې لیډونه منقطع شوي دي.
2. Remove the battery compartment cover and batteries.
3. Locate the fuse(s) inside the compartment. The MM20HV typically uses a 200mA/250V fast-blow fuse for the mA range and a 10A/250V fast-blow fuse for the 10A range.
4. Carefully remove the old fuse and replace it with a new fuse of the exact same type and rating.
5. Replace the batteries and battery compartment cover.

مهم: Never use a fuse with a different rating or bypass a fuse. This can damage the multimeter and pose a serious safety hazard.
