Hello, Does anybody have the manual and the schematics of this multimeter. R20 is blown up and I do not know its value. With kind regards,

Is it an analog meter? You may be able to experiment to find an acceptable value. Often the Rx1 resistor is the one to burn out - often in the 10 to 12 ohm range.

If it is a range setting resistor, then try to determine the values of the resistors on the other ranges and then make an intelligent guess or calculation.
For example, a string of resistors in a potential divider may consist of 9M, 900K, 90K, 9K, 900R, 90R, 10R.

Thx for the answers. It is a digital 4 digit autoranging multimeter. I have replaced the resistor by a 4,7R and the multimeter now seems to give the right reading for the intensity 20-200 mA generated by a intensitygenerator and a second multimeter in serie with the defect one. So I will try to validate the value following your guess. With kind regards
