Martindale E3640

The Metrohm E3640 is a 4kV AC flash tester, capable of operating from either a 115V or 230V supply, at 50 or 60Hz. The Twin 3 1/2 digit LCD displays show both output voltage and leakage current. The unit is built into a hard carry case, making it robust and portable. There are there modes of operation, where the fail lamp illuminates and a buzzer will sound:

Trip: will trip when a pre-determined current is exceeded Breakdown: fast transients can trigger the trip Burn: where the trip function is by-passed and the fault current flows continuously to expose the fault
