UNI-T UT61E Digital Multimeter Continuity Test Not Working
fabry891:
Hello everyone,
I have had a UNI-T UT61E digital multimeter for a few years now, which has always worked well for my hobby use.
Today I noticed that in continuity test mode if I put the two leads in contact, even with a low ohm value less than 1, I do not hear the beep, but I hear a quick beep only when I disconnect the leads. Also in DC voltage test mode, even without leads inserted, I have a value of about -0.3 V.
I also tried to power it with an external power supply, to exclude the battery problem, but the problem persists.
I wonder if anyone has already had the same problem as me and how to solve it.
Thanks.
Kleinstein:
Using an external power supply is usually a bad idea.
Geting -0.3 V DC when open is a bad sign and likely not directly related to the continuity problem.
With a handheld DMM there is usually is low chance for a repair, as parts are hard to get and new calibration may be needed, that may be difficult (rarely the procedures are public) or expensive to get.
A possibly issue effecting multiple areas could be a damage from humidy or a leaking battery. If no longer under warranty, maybe have a look.

That sounds bad.
What was the previous thing you did to it?

Check your test leads/try another set.

Bad leads won't subtract 0.3V DC from the input, especially when they aren't connected.
