    I am an a look out for a schematic/diagram for a multimeter Buepoint MT155.One of resistor blowed up and I can't read the numbers on it so I need the schematic/diagram.
    Thanks to all.

    A blown resistor is a bad sign. Something else may be damaged also. Can you supply a photo of the bad part?

    If the problem is truly an open resistor, you could start with, say, a 1MΩ test resistor. If that does nothing, move to 470kΩ, 100kΩ, and so on. This process may not get you to an accurate replacement but it might tell you if the meter is still functioning.
