If the voltage profile of a digital multimeter is damaged, the specific method of repair may vary, depending on the cause of the damage and the specific circumstances. Here are some possible fixes:
< br >
1. Replace the fuse: Sometimes, the voltage file damage of the meter may be caused by a burned fuse, and only the fuse needs to be replaced at this time.
< br >
2. Replace the capacitor or chip: If the voltage of the meter is caused by the capacitor or chip damage, it needs to be replaced to ensure the normal operation of the meter.
< br >
3. Clean the inside of the meter: If the inside of the meter is loose or too much dirt may cause the voltage stop to fail, you can clean the inside and re-fix the components to see if the voltage stop can be repaired.

Please note that if you are not a professional electrician, do not attempt to repair a digital multimeter yourself. It is best to give it to a professional maintenance personnel for repair.
If the current is good, the IC is not bad; Usually a series of voltage divider resistance 9M 900K 90K 9K 900 100 euro in a damaged or deranged, may also be printed board, switch damage; Check for exclusions one by one.
