    Hi.. Does anyone know how to repair Sanwa PM3? I just used it to measure the voltage of mosquito racket zapper and the display went blank. The multimeter max rating is 500volts. Is the mosquito racket zapper voltage higher than 500volts?

    The "mosquito zapper racket" could have several thousand volts on the grid.

    You should not have used the meter to try to measure the voltage.

    You may have blown the meters' internal fuse, or simply fried the meter. If the fuse inside the meter is OK, throw the meter in the trash and buy another.

    The thing is the multimeter doesn't have fuse inside.

    Then throw the meter away, and buy another one. I suggest getting a Fluke. They are not cheap, but one good Fluke meter will last you for a very long, long time.

    A good Fluke also has protection circuits so it won't disintegrate when you try to use it outside its limits. I've had mine for 32 years and never had to repair anything but the fuses.

    The packaging on the mosquito zapper raquet says 2700Volts, wonder how the Fluke would handle that?
