Hi everybody , and i want to thank you for the great electronics lectures available on this website .
I am a 2nd year student in automation systems based on programmable automata and microcontrollers .
So i have a Digital clamp meter that measures everything but the AC voltages .
I have already posted my problem in another forum but didn't achieve much progress in the troubleshooting that was mainly based on guessing .
The reason i am planning to fix my meter is that it is a high quality meter that measures high currents in both AC & DC , and it is about 300 dollars .
What could be causing this problem ??
list of ICs on the motherboard :
NJM022B : dual low power operational amplifier
TS27L2C : Precision very low power cmos dual amplifiers
OP07 : Ultralow offset voltage operational amplifier
AD736 : Low power , true RMS to DC converter
AIC1578 : High efficiency step down DC/DC converter
HEF4066B : quadruple bilateral switches
NJU 9210 : 3.3/4 digit sigle chip digital multimeter LSI
