UNI-T UT16E : no more beeping in continuity test

[pierre-françois]

Hello everyone.

Few days ago my UT16E stops beeping in continuity test mode but still beeps in diode test mode.
I measured the voltage applied in these 2 modes :
Continuity test mode : - 3V
Diode test mode : + 2,84 V
According to operating manual "open circuit voltage in around - 1,2 V" in continuity test mode ; so may be it's a start

Has anyone already encountered this issue ? Any Clue ?

Thanks for future help
