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. Mark Z. |

put finger to keyboard and composed: 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, 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. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

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 |
