Electronic torque wrench is a necessary tool in our daily life. Because of its small size and convenient use, electronic torque wrenches are widely used in many industries. Of course, even the best electronic torque wrench products are used. A long time, it will inevitably encounter some failures, consumers first response after a failure is more anxious, the next is to send to the factory maintenance, or call the manufacturer, in fact, if we can learn more about some electronic torque wrench As for the maintenance method, even if there are some big problems, like damage or something, there is no way to deal with it. Like some glitches, such as short circuit, unable to turn on, etc., we can easily solve the problem and do not know where the electronic torque is. The user of the spanner repair method does not matter. Shanghai Shiheng Electronic Torque Wrench Small Piece Here we have compiled an electronic torque wrench repair method for electronic torque wrench users to refer to, hoping to give some help to the electronic torque wrench user friend.
Electronic torque wrench hand maintenance method one:
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 electronic torque wrench, the electrolytic power should be first
2. The positive and negative electrodes of the container should be short-circuited, and do not use the lead line instead of the lead to discharge the capacitor, 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.
B. Electronic Torque Wrench 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 logic pens and oscilloscopes to detect signals, be careful not to contact the probes at the same time.
2. Measure the pin, because the essence of this situation is to form a short circuit under power.
C. Electronic torque wrench repair method three:
1, first check your electronic torque wrench sensor connection cable is connected, is there a sensor signal line
2, short circuit or open circuit, as well as welding whether there is a phenomenon of welding.
D. Electronic Torque Wrench Maintenance Method 4:
1. When the maintenance of the wet environment is faulty, it is necessary for the circuit board's circuit multimeter to measure whether each point is unobstructed.
2. Because the main fault in this case is the corrosion of copper foil. For circuit boards that are corrosive, we can use 95% industrial alcohol to clean and wipe, so as not to cause corrosion of the larger mask.
3. When the internal circuit of the electronic torque wrench is inspected, if the contacts and the circuit board of the mounting component are coated with insulating varnish.
E. Electronic Torque Wrench Maintenance Method 5:
1. When measuring the parameters of each point, you can use ordinary hand-sewing needles to weld the pen on the multimeter so that the points can be directly measured by piercing the paint layer without peeling off the paint layer in a large area. This will cause oxidation of the copper foil.
