New multimeter always shows a resistance of 1
Is my multimeter faulty?


In your photo, we can see that the probe leads are plugged into the correct sockets on the meter, and you have selected the 200 kΩ resistance range on the dial.

As you may know, a multimeter display showing only "1" in the left digit position, usually means over-range i.e. the measured value is in excess of the maximum for the selected range. On meters with only manual range selection, like yours (or when using manual range selection on an auto-ranging meter) you could switch to a higher range, to see if the meter then displays a value within that higher range.

In your picture, you have selected the 200 kΩ range, so your meter display suggests the resistance is >200 kΩ which is obviously incorrect for the low resistance expected from shorted probe leads.

Therefore either the multimeter, or one (or both) of the probe leads is faulty.

You could try unplugging both leads from the meter, and shorting the "COM" &amp; "V&Omega;mA" sockets (i.e. the sockets where you currently have the probe leads), using a short length of known-good wire.


If you then see a low resistance on the meter, then the meter is (at least basically) OK and you can move on to test the probe leads individually, by replacing that known-good piece of wire with each probe lead, in turn.
If you still don't see a low resistance on the meter with a known-good length of wire shorting those two sockets, then that points towards an internal problem with the meter itself.


Note: As shown in the question that you linked, it is possible to have incompatible probe leads, if they don't fit correctly into the sockets on your new meter, and hence don't actually make electrical connection with the meter itself. Be aware of that possibility.
