Dude, I have the same multimeter. I confused the wires around the position selector switch. Can you send me your photo?... -

Re: Fixing a multimeter based on VC9805 schematic
I couldn't find a fault anywhere, then I wanted to replace this part and yes it works as before now, temperature, voltage, all... thank you very much for your help......Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
I solve the problem. I change the u2 integrated diagnostic tl062 in the diagram and the multimetrem started working as it old. If anyone experiences the same problem with me, remember this and benefit from this information. Thank you so much to the good people who answered my questions here...Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
sir, If the multimeter will measure the battery at 20 volts dc, which ways do the contactor wires touch in this diagram?...Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
sir,
buzzer = 2.90 v
temperature = 38.1 millivolts
in low- in hi= 0.00
vref+-vref- =1
v- v+ = battery voltage 9.0
v- and com varies 179 mv, 190, 110...Leave a comment:

vc9805 multimetre arızası
hello, I have the same vc9805 multimeter, whose photos and schematic I have attached below. After replacing the battery only ohm and diode (buzzer) measurements work, other measurements do not work voltage, current ... none. Only the number 1 remains on the screen. When I measured the components, I couldn't find any problem parts. If anyone has any idea, what should I do?...Last edited by poker; 06-24-2022, 10:24 AM.Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
Now the multimeter is working but it doesn't measure voltage and current. Do you have any idea about it?Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
Yes, it doesn't turn off automatically. you guys are great. thank you. good people like you will save the world... so why can't I measure voltage and current? only ohm and diode (buzzer) are working. I couldn't find any other short circuit, contactor wires are in place. Could you please give an idea for this as well?Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
Thank you for your reply. The m6 smd I marked in the photo and diagram was a short circuit. I don't have an m6 transistor right now. What should I do to operate the multimeter?...Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
you are right then we have another problem that i need to find ?Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
yes, the problem is that the m6 is short circuited, but now I don't have the m6 transistor. How can I bypass this transistor in the circuit? until i find the transistor?Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
sir, I think this transistor is responsible for short circuit protection at the input. Can I bypass this transistor, which is specified as m6 in the diagram of the friend who opened the topic, what do you think until I find the transistor?Leave a comment:

Re: Fixing a multimeter based on VC9805 schematic
Hello again, I detected a short circuit in the m6 (s9015) transistor in the multimeter. I can't find the same transistor, which transistor can I use instead? can't find the same transistor, which transistor can I use instead?Leave a comment:
