Technical Indicators
| Test power | |||
| Fixed test voltage | 100V, 250V, 500V, 1000V, 2500V, 5000V,10000V | ||
| Custom Test Voltage | 50V~10000V The minimum step voltage is 10V. When using the single-button shuttle control, the step voltage value will automatically switch between 10V, 100V, and 200V with the speed of the shuttle. The higher the speed, the higher the step voltage value. |
