- Simultaneous insulation voltage testing: test insulation voltage of multiple objects at once, including insulation between two pins of connectors, as well as switches and buttons. - Convenient winding insulation testing: suitable for insulation tests between windings such as motors, using power-frequency, high-frequency, phase insulation, and insulation test of shell cores. - Broad compatibility for withstand voltage measurement: NIMOS, PMOS, IGBT, triode, unidirectional thyristor, voltage regulator diode, light-emitting diode, rectifier bridge, varistor, ceramic gas discharge tube, and electrolytic capacitor. - Practical use scenarios: - In a maintenance shop, verify insulation integrity between connectors and control switches to ensure safety. - In motor service or manufacturing, assess winding insulation and core shell insulation during diagnostics or QA. - In electronics production, screen withstand voltage for diodes, transistors, capacitors, and rectifier assemblies to confirm reliability.
