    Hi all

    I purchased as Digitech multi meter Qm1321 and just blown a fuse, having troubles finding replacement fuse. The fuse that was install, a 0.5 A 500volt 6mm x 30mm ceramic , as long as the ampage and volt is the same all can be good. ??? can any one reconmend as suitable replacement. finding a lot of 6.3 x 32. if it fits can i use this type, sor-da kinda new to electronic, done a lot of study in the health field, so this is all new to me.

    Thank in advance

    1. Go to http://australia.rs-online.com/
    2. Type "fuse" in the search box and select "fuses - Cartridge fuses"
    3. In the Diameter section, select 6, 6.3, 6.35, and 6.4mm and "apply filters"
    4. In the voltage rating section, select everything >= 500V and "apply filters"
    5. In the current rating section, select 0.5A and 500mA and "apply filters"
    6. In the "high rupture capacity" section, select "yes" and "apply filters"
    7. I have 4 remaining, you probably want the one rated as "F".
    You're looking at $13.55 for 10 of them delivered to your door.

    There may be other options.

    The fuse that i pulled out of the multimeter had a voltage rating of 500v but the cover indicated that their should be rated at 1000 volts, The housing for the fuse looks like it is 32mm, has the wrong fuse been install in this device? Anyway 500ma will do. ( i hope).
    I don't play around with 240 volts and only dc curren.


    Product i found.

    The correct fuses are very expensive. I had to replace one in a second hand 4 1/2 digit multimeter and it cost me almost as much as the meter!

    Cheap multimeters often don't contain the same rating of fuses and it's possible that less reputable manufacturers swap out the fuse for a cheaper one.

    They are mostly important when dealing with high energy power sources. If you're only dealing with low voltages and currents, they may be unnecessary.
