漏电开关测试仪使用方法 Use method of leakage switch tester 　　1、测试前的准备 测试仪接电源前，仪器的“电源开关”应在断开位置，电源应接在漏电保护器电源侧(AC220V)，相、零线不能接错，测试线穿过零序互感器后接在测试仪电源的同相相线上。测试仪的功能开关放在“予置”位置，检查接线正确后，将测试仪面板上的“电流调节”电位器逆时针旋转调到零位，压下“电源开关”，此时，毫安表、毫秒表指示应为零，如不为零，按一下“复位”按钮即可。 1, test preparation before the tester is to connect power, the instrument of "power switch" should be in the off position, the power supply can electric leakage protector in the power supply side (AC220V), phase and zero line can't wrong, after the test line through the zero sequence current transformer in the power tester with the phase line. Tester is the function of the switch on "in the" position, check the wiring right after the "current" on the instrument panel potentiometer counterclockwise to zero, press the "power switch", at this point, the milliammeter, millisecond table instructions should be zero, if not zero, press the "reset" button. 　　2、漏电保护器本身漏电动作电流或漏电不动作电流测量(负载侧引线应拆开) 机上功能开关放在“予置”位，将漏电保护器投入后，此时按一下测试按钮，顺时针缓慢调节测试仪面板上的“电流调节”电位器，则测试仪的毫安表应有毫安数值显示，电流逐步增大，直至漏电保护器动作，此时毫安表显示的读数，即为漏电动作电流。 漏电不动作电流测量，调节电流方法同上，当电流值达到规定值时，按一下“复位”按钮，电流回零，再按一下“测试”按钮，漏电保护器不动作，即为合格。 2 leakage current action or leakage, leakage protector itself not action current measurement (lateral load lead should be apart) function switch on "in the" on board, will begin after the leakage protector and test button at this time, slowly clockwise to adjust the instrument panel "current adjust potentiometer, the tester should be milliammeter ma numerical display, current increases gradually, until the leakage protector action, milliammeter display reading right now, is the leakage current action. Leakage is not current measurements, adjust current method as above, when current value reach the specified value, press the "reset" button, the current back to zero, press the "test" button again, the leakage protector is not action, is qualified.
