Wrong AC Reading on UNI-T UT61B
« on: September 13, 2023, 12:39:23 pm »
Hi all, I am experiencing a wrong reading for all AC voltages, it seems that the read voltage is 1/2 that what it should be . I guess that it is using only one cycle of the AC voltage . Does anyone know which component can cause this  issue ?

avoid a mistake to measure anything inside by the same unit ( as itself) it may die
