Torque wrench tester is a professional tester for testing torque wrenches in industrial production. Many users will encounter problems when using the torque wrench tester, which will lead to a significant decrease in work efficiency. How to solve this problem? Then the following Shanghai hard-working Xiaobian came to tell you about some ways to repair the torque wrench tester.
Torque wrench tester repair method:
A. Torque wrench tester maintenance method 1:
1, first check your torque wrench tester sensor connection cable is connected, is there a sensor signal line short circuit or open circuit, as well as welding whether there is a phenomenon of false welds.
B. Torque wrench tester maintenance method 2:
1, then check whether your instrument is fully charged, if it is not enough charge, it is also easy to cause, can not normally use the boot, the value is not stable, on-line beat. When using a logic pen or oscilloscope to detect signals, be careful not to let the probe touch the two measurement pins at the same time, because the essence of this situation is to form a short circuit when the power is applied.
C. Torque wrench calibrator maintenance method three:
1. When using the multimeter's ohmic block, remember not to measure with electricity. When detecting the filter capacitance in the power supply of the torque wrench tester, the positive and negative electrodes of the electrolytic capacitor should be short-circuited first, and the lead should not be used to discharge the capacitor with a lead wire when short-circuiting, because it is easy to blow the core wire. A 220-volt, 50-watt light bulb with a cap lead can be taken and connected at both ends of the capacitor. At the moment of discharge, the bulb will flash.
D. Repair method of torque wrench tester:
1. When measuring the parameters of each point, you can use ordinary hand-stitched needles on the pen of the multimeter so that the points can be directly measured by piercing the paint layer without using a large area.
Peel off the paint, which will cause the oxidation of the copper foil.
E. Torque wrench tester maintenance method five:
1. When the wet environment is in maintenance failure, it is necessary for the circuit board's circuit multimeter to measure whether all points are unobstructed. The main fault in this case is the corrosion of copper foil. For corroded circuit boards, we can use 95% of industrial alcohol. Clean and wipe, so as not to cause more corrosion of the mask. When testing the internal circuit of the torque wrench calibrator, if there is an insulating varnish on the contacts and circuit board of the mounting component.
