AC mode and NCV mode do not work in Uni-T UT210E current clamps. The display shows OL.

Check pnp/npn transistor pairs, ptc devices if the other functions ok. If the main chip is failed, you can find a replacement and maybe firmware for it. This clamp meter is a popular and well documented instrument. Good luck. 0 2024, September 15 - 10:43 #548450 lcsaszar 9 years 7 months* DC voltage and clamp current measurement is OK? 0
