扭力扳手維修方法一：
Torque wrench maintenance method 1:
1、檢查你的扭力扳手的傳感器的連接線是否連接好，是不是有傳感器的信號(hào)線有
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、短路或者斷路，還有焊接點(diǎn)是否有虛焊的現(xiàn)象。
2. Short circuit or open circuit, as well as whether there is false soldering at the welding point.

1、然后檢查你的儀表是否充電飽和，如果充電不夠的話也容易引起，不能正常使用開(kāi)機(jī)、示值不穩(wěn)定，上線跳動(dòng)。使用邏輯筆、示波器檢測(cè)信號(hào)時(shí)，要注意不使探針同時(shí)接觸兩個(gè)
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、測(cè)量引腳，因?yàn)檫@種情況的實(shí)質(zhì)是在加電的情況下形成短路。
2. Measure the pin, because the essence of this situation is to form a short circuit when the power is applied.

C. Torque wrench maintenance method 3:
1、用萬(wàn)用表歐姆擋時(shí)，切記不要帶電測(cè)量。檢測(cè)扭力扳手的電源中的濾波電容時(shí)，應(yīng)先將電解電
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、容器的正負(fù)極短路一下，而且短路時(shí)不要用表筆線來(lái)代替導(dǎo)線對(duì)電容器進(jìn)行放電，因?yàn)檫@樣容易燒斷芯線?？梢匀∫恢粠纛^引線的220V，50W的電燈泡，連接在電容器的兩端、在放電的瞬間燈泡會(huì)閃光。
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.
D.扭力扳手維修方法四:
D. Torque wrench maintenance method 4:
1、測(cè)量各點(diǎn)參數(shù)時(shí)可用普通手縫針焊在萬(wàn)用表的表筆上，以便刺穿漆層直接測(cè)量各點(diǎn)，而不用大面積剝離漆層，這樣會(huì)造成銅箔的氧化。
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.
E.扭力扳手維修方法五:
E. Torque wrench maintenance method 5:
1、潮濕環(huán)境維修故障時(shí)，對(duì)于線路板的電路萬(wàn)用表測(cè)其各點(diǎn)是否通暢很有必要
1. It is necessary to measure whether the points of circuit board are unobstructed by multimeter when repairing faults in humid environment
2、因?yàn)檫@種情況下的主要故障是銅箔腐蝕對(duì)于有腐蝕的電路板我們可以用含量95%的工業(yè)酒精清洗和搽拭，這樣以免引起更大面具的腐蝕。
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、扭力扳手的內(nèi)部電路檢測(cè)時(shí)，如果安裝元件的接點(diǎn)和電路板上涂了絕緣清漆
3. When testing the internal circuit of torque wrench, if the contact and circuit board of mounting components are coated with insulating varnish
