Cropico Microohmmeter Failure Cause Analysis Troubleshooting Method.
1. Press the "through" button, and the indicator light does not light up.
dFuse rd blows. d. Replace the fuse.
2. The power plug connection line is disconnected. 12. Connect the connecting cable.
2. Press the "on" button. The B junction of BG1 is not self-ligating. Replace tubing with larger B junctions.
3. The working switch is set to the "calibration" and "measurement" positions, and the indicator does not indicate that the internal and external connection lines of the calibration rod are disconnected. Plug in the cable.
4. When the range switch is set to a certain range block, the working switch is set to the "calibration" position, and the current limiting electric yang value of a certain range block cannot be adjusted to a full scale. Reduce the yang value of the current-limiting electric positive.
5. When the range switch is set to a certain range, T is set to the "correction" position of the switch, the indicator can not be adjusted to the full scale, the power supply will be cut off or the indicator can not be adjusted back to the full scale if the indicator exceeds the full scale, the power supply can not be cut off, and the oscillation circuit of the three-point oscillator is out of balance. Trimmer capacitor c. capacitance;Pull people or shorten the fan line|Laps L:, L: and Aluminum Flag L. Relative position: Increase or decrease the inductance of the tubular coil L2, L, .
6. When the range switch is set to a certain range block, the working switch is set to the "measurement" position, and compared with the standard resistance, the indication value is larger or smaller, and the shunt resistance value of a certain range block increases or decreases. Reduce or increase the shunt resistance.
