Multimeter question

(1/2) > >>

Arislan:
I always thought that holding together the tester tips of a multimeter in Ohm mode would read zero. Mine keeps jumping all over the place. Any ideas if that is normal?

polar bear6:
is it realatively big numbers, it might be that your not holding them totaly together, and it may be touching your finger or something.
i just checked with mine, and it jumps from 6-7 ohms....
maybe you have blown the fuse, i did that once, and the numbers were flying like hippies on crack, it was wierd.

Arislan:
it still measures voltage from batteries perfectly, just not ohms from anything.

dunk:
yup, not normal.
i'm not at home just now so i can't check but i'm fairly sure mine reads zero on all settings when you measure resistance and press the probes together.
a multi meter really is one of the components you don't want to economise on when buying.
i ended up buying quite a good one a load of years ago and have never regretted it.

you don't need lots of features (mine is only ever used for measuring voltage, current and resistance) but having a stable meter that you don't have to worry about damaging with excessive current (within reason) is definitely a good thing.

dunk.

sdk32285:
also i have found that meters that beep when shorted( ie continuity meter) are very usefull.
