Check the control, measurement, and protection signal circuits according to the design requirements, the cable calibration is accurate, the wiring terminals are tight, and the mechanical parts are well checked.<br>5.1.2. The insulation and withstand voltage test is<br>measured with a 500V megohmmeter, and the insulation resistance value should be greater than 1MΩ. The ground power frequency 1000V withstand voltage test is only performed on the control circuit, and the duration is 1 minute; when the circuit insulation resistance is greater than 10MΩ , It can be replaced by a 2500V megohmmeter. The duration is 1 minute. The 24V control circuit of the diesel engine control panel should not be subjected to a pressure test.<br>5.2.
