扭力扳手维修方法一：
Torque wrench maintenance method 1:
1、首先检查你的扭力扳手的传感器的连接线是否连接好，是不是有传感器的信号线有
1. First of all, check whether the connection wire of the sensor of your torque wrench is connected well, and whether the signal line of the sensor has
2、短路或者断路，还有焊接点是否有虚焊的现象。
2. Short circuit or open circuit, as well as whether there is false soldering at the welding point.

1、然后检查你的仪表是否充电饱和，如果充电不够的话也容易引起，不能正常使用开机、示值不稳定，上线跳动。使用逻辑笔、示波器检测信号时，要注意不使探针同时接触两个
1. Then check whether your instrument is saturated with charge. If it is not charged enough, it is easy to cause it. It can not be used normally. The indicator value is unstable and the line jumps. When using logic pen and oscillograph to detect signals, it is necessary to avoid the probe contacting two probes at the same time
2、测量引脚，因为这种情况的实质是在加电的情况下形成短路。
2. Measure the pin, because the essence of this situation is to form a short circuit when the power is applied.

1、用万用表欧姆挡时，切记不要带电测量。检测扭力扳手的电源中的滤波电容时，应先将电解电
1. When using the ohm block of the multimeter, remember not to measure with electricity. When testing the filter capacitor in the power supply of torque wrench, the electrolytic power should be applied first
2、容器的正负极短路一下，而且短路时不要用表笔线来代替导线对电容器进行放电，因为这样容易烧断芯线。可以取一只带灯头引线的220V，50W的电灯泡，连接在电容器的两端、在放电的瞬间灯泡会闪光。
2. The positive and negative poles of the container are short circuited, and do not use the probe wire to discharge the capacitor instead of the wire, because it is easy to burn the core wire. You can take a 220 V, 50 W light bulb with a lamp cap lead, which is connected to both ends of the capacitor, and the bulb will flash at the moment of discharge.

1、测量各点参数时可用普通手缝针焊在万用表的表笔上，以便刺穿漆层直接测量各点，而不用大面积剥离漆层，这样会造成铜箔的氧化。
1. When measuring the parameters of each point, ordinary hand sewing needle can be welded on the probe of multimeter, so as to pierce the paint layer and directly measure each point without stripping the paint layer in large area, which will cause oxidation of copper foil.

1、潮湿环境维修故障时，对于线路板的电路万用表测其各点是否通畅很有必要
1. It is necessary to measure whether the points of circuit board are unobstructed by multimeter when repairing faults in humid environment
2、因为这种情况下的主要故障是铜箔腐蚀对于有腐蚀的电路板我们可以用含量95%的工业酒精清洗和搽拭，这样以免引起更大面具的腐蚀。
2. In this case, the main fault is copper foil corrosion. For the circuit board with corrosion, we can use 95% industrial alcohol to clean and wipe, so as to avoid causing greater corrosion of the mask.
3、扭力扳手的内部电路检测时，如果安装元件的接点和电路板上涂了绝缘清漆
3. When testing the internal circuit of torque wrench, if the contact and circuit board of mounting components are coated with insulating varnish
