    Help Fixing UT61E MultiMeter continuously beeping

    ok i guess it's the chip, i've tracked the 10 A path on the bard which go directly to the Chip , and as I've mentioned before i shorted it with the 9v+ from the battery so do you agree with me it's the chip or is it something else? and if it's the chip is there a way maybe to reset it or it's done

    Help Fixing UT61E MultiMeter continuously beeping

    i was using the RED probe on 1 it to be able to make the measurement does that mean it's the base? not the emitter or collector ? to be clear, the issue happen when i shorted between those two circles in red i show on the schematic while the battery exist and the multi-meter on the A scale

    the multi-meter doesn't give any read on DC scale, ampere scale, ohm scale i mean i tried to test some dc voltage, ampere and resistors no reads at all i used analog multi-meter on 1x ohm scale to test the transistors 1 red,2 black = 8Ω > 1 red,3 black = 8Ω > 2,3,4 = shorted 1 black , 2...
