Features:
1. Can test the insulation voltage of objects at the same time. For example, switches, buttons, and insulation voltage tests between the two pins of connectors.
2. The product is small
3. Easy to carry and store
4. It is also convenient to test the insulation between windings, such as motors, power frequency transformers, high-frequency transformers, phase insulation, and insulation test of shell cores
5. Widely used to measure: NIMOS/PMOS/IGBT/triode/unidirectional thyristor/voltage regulator diode/light-emitting diode/rectifier bridge/varistor/ceramic gas discharge tube/electrolytic capacitor/withstand voltage value
