PROMAX PD-618 DIGITAL MULTIMETER

[diminute]

I have a PROMAX PD-618 Digital Multimeter, I want to find the schematic of this equiment.

My multimeter when is turn on is not adjust to 0.000 volts, it has 0.014 to 0.003 volts and it begin to oscilate. In a few minutes it is stable, but never is 0.000 volts. If i put the equiment in the sun ligth for a quater of hour more less then your lecture is good.

I clear contacts and electronic board but the problem not desapear.

With the schematic is possible that i can repair.

Somebody here can help me ????

No, yet

I asked only to you.

I can't find the schematic in the WWW.

So I suggest you contact Promax. They may know what the problem is right off, and they may be willing to send you a schematic. www.promax.es.

Then you may be out of luck. I doubt anyone else will have the schematic for this. Keep bugging Promax, maybe someone will respond.
