1. Material: ABS/PVC/Silicone2. AC voltage: 0V-1000V3. DC voltage: 0V-750V4. Capacitance: 0nF-99.99mF5. Resistance: 0Ω-19.99MΩ6. Frequency: 9.999Hz-999.9kHz7. Count: 199998. Insulation resistance measurement: connect the test leads, select the voltage range on the dial, press TIME to set the time, press TEST to start, and the test is complete when the triangle indicator light goes out.9. Polarization index (PI) Measurement: the polarization index is measured because insulation is sensitive to temperature and humidity. Initial measurements are inaccurate due to interference current. Long-term measurement and calculation of this index are necessary to assess insulation quality and aging.10. Absorption ratio (DAR) Measurement: determines if moisture affects the insulation resistance value of the device by measuring the insulation resistance value after 1 minute and the insulation resistance absorption ratio after 15 seconds.11.
