Digital torque wrench repair method one. 1. First check whether the connecting line of the sensor of your digital torque wrench is connected well and whether there is a signal line of the sensor. 2. Short circuit or open circuit, and whether there is virtual welding at the welding point

Digital torque wrench repair method one
1. First check whether the connecting line of the sensor of your digital torque wrench is connected properly and whether there is a signal line of the sensor
2. Short circuit or open circuit, and whether there is virtual welding at the welding point

Digital torque wrench repair method two
1. Then check whether your meter is fully charged. If it is not charged enough, it will simply cause it. It cannot be started normally, the indication value is unstable, and the line jumps. When using logic pen and oscilloscope to detect signals, be careful not to touch the two probes together.
2, measuring star pin, because the essence of this situation is to form a short circuit under the condition of power.

1. When using multimeter ohmic junction, remember not to charge measurement. When detecting the wave-extinguishing capacitor in the power supply of the digital display torque pole hand, the electrolytic electrode should be first.
2. The positive and negative poles of the container are short-circuited, and when short-circuited, do not use the meter pen wire to replace the wire to discharge the capacitor, because the core wire is simply burned. A 220V,50W light bulb with lamp head lead can be taken and connected to both ends of the capacitor. The light bulb will flash at the moment of discharge.

1. When measuring the parameters of each point, ordinary hand stitching can be used to weld on the meter pen of the multimeter, so as to pierce the paint layer and directly measure each point without peeling off the paint layer in a large area, which will form oxidation of copper foil.
Digital torque wrench repair method five
1. When repairing problems in humid environment, it is necessary for the circuit multimeter on the road board to measure whether each point is clear. Since the main problem in this situation is copper foil corrosion, we can clean and wipe the corroded circuit board with 95% industrial alcohol, so as to avoid causing more corrosion of the mask. When the internal circuit of the digital torque wrench is tested, if the contact of the mounting component and the circuit board are coated with green varnish.
