Hello everybody
I've found an issue with my DMM TENMA 72-7755. When external temperature is below around 10=B0C it doesn't power on : LCD begins to lit on but finally slowly stops and the DMM doesn't beep.
Of course battery cell is correct and after a few minutes at higher ambient temperature it runs correctly.
Anybody has the schematic of this device. I guess some capacitor may be particulary sensitive to temperature but without original value I'm sure to replace it.
Thanks in advance
