all-sun Digital Insulation resistance tester & Auto-range DC AC Voltage Megohm Meter

Introduction
This instrument is accurate, reliable and easy to operate. For insulation resistance test, you can
change the test voltage among 250V 500V and 1000V. It can also be used to test ACV,
resistance which is less than 200Ω, and test for continuity. You can use it to test
transformer, motor, cable, switch, electrical appliance as well as to do insulation resistance test.
