My multimeter, DT830B Digital Multimeter, is giving a negative average of -3 volts by default that means that even without connecting the leads it reads a negative number. The only part of the multimeter that dosen't appear to have the bias is the ohms reading ...
When I connect it to a 9 volts battery, it reads 6 volts on it, if i connect it to a simple cellphone charger of 5 volts DC of 1.2 A it reads 2 volts.
I was wondering if this it is broken or with some kind of adjustment problem, does the variable resistor inside it serve this purpose? I did some research on google came with no answer to the problem ... :|
Does some one know what might be the problem?
