Pressure tester high precision electrolytic capacitor two triode IGBT and other pressure measuring instrument

One、Why do you want to carry out pressure test
Semiconductor components during use，Often cause reverse pressure drop due to aging and other reasons，Breakdown leakage occurs during work（Even short circuit burning），Causing the equipment to work abnormally，And such problems often occur in the case of equipment power failure，Can't test with ordinary Multimeter（No complete thermal breakdown short circuit），Not easy to observe，At this time, we will test with a pressure tester.（Different component test methods are slightly different，See the introduction）。
Two、Zhao Gong brand pressure tester function technical indicators：
1、Working power supply：DC 5V（Contains lithium battery can be used in hand）；

Three、Which components can the pressure Tester measure：
1、Test various crystal diodes、Triode、Triac、Field effect tube、IGBT、Reverse maximum withstand voltage value of components such as power module；
2、Test the pressure sensitive resistor、Voltage value of protection elements such as transient diodes;
3、Test whether the leakage current of electrolytic capacitors exceeds the standard；
4、Test the insulation performance of electrical products。
