Does the head comes off. what is the difference between 389 vs 389B

No the head does not come off that I know of, I have never taken it off on mine. The 389B is the upgraded version of 389 adding micro amps and non-contact voltage testing. I like my 389B,

Have anyone have problem putting test leads into meter? Seems to have black piece over both test lead opening.

Great Tester

Have used this unit for many years, think the latest one is number 6. As a electrician and refrigeration technician is fills all the gaps other testers don't. Greatest point is the size of clamp for amperage, you can usually get it snuck in areas others don't on 3/0 and little bigger. Price is great to. I have Fluke meters, but this is preferred tester.

Stopped reading MFD microfarads after 8 months

I bought the UEI model DL389B “True RMS” multimeter. I specifically got this for HVAC so I could read microfarads on capacitors. I bought it eight months ago and it was working decently until now. It won’t read microfarads on capacitance. And that was the main reason why I got this multimeter. I put in fresh batteries to no avail. Very disappointed.
