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.It is also convenient to test the insulation between windings, such as motors, power frequency , high-frequency , phase insulation, and insulation test of shell coresWidely used to measure: for NIMOS/for PMOS/for IGBT/for triode/ unidirectional thyristor/ voltage regulator diode/light-emitting diode/rectifier bridge/varistor/ceramic gas discharge tube/electrolytic capacitor/withstand voltage valueThe product is small, Easy to carry and storeSpecification:C: Red light - pure English silk screen versionColour:M:WhiteMaterial:PCBSize:9.8x7x3.7cmPackage Contents:1 x TesterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
