Measuring method of generator insulation resistance

The ES3025E digital insulation resistance meter (5000V) has a range of 0 to 200GΩ, a minimum resolution of 0.01MΩ, a rated voltage of 250V/500V/1000V/2500V/5000V, a DC voltage of 0 to 1000V, and an AC voltage of 0 to 750V. Data storage 500 groups. The following is the measurement of the insulation resistance of the generator. The ES3025E digital insulation resistance meter (5000V) has a range of 0 to 200 GΩ, a minimum resolution of 0.01 MΩ, a rated voltage of 250 V/500 V/1000 V/2500 V/5000 V, and a DC voltage of 0 to 0. 1000V, AC voltage: 0 ~ 750V, data storage 500 groups. The following is the application of measuring the insulation resistance of the generator
Open the Energy ES3025E digital insulation resistance meter (5000V) instrument box, accessories are: meter: 1 set, high voltage rod: 1 red, high voltage test line: 2 (black, green one each), battery: 1.5V alkaline Battery 6 sections, manual, warranty certificate: 1 set, instrument box: 1
