DescriptionThe HT Instruments M74 is a multifunction installation tester and digital multimeter (DMM), not a dedicated high-voltage insulation (Hi-Pot) tester. While it performs insulation resistance measurements up to 500VDC, which is a type of insulation test, a true "Hi-Pot" test typically involves much higher voltages to test dielectric strength. The M74 is suitable for electrical safety checks in residential and civil installations. |
