Metrohm E3640

This digital flash tester is a portable mains operated instrument, capable of operating from either 115V or 230V supplies at 50/60Hz. It can apply up to 4kV AC and displays both output voltage and leakage current on the twin 3½ digit LCD’s.

The fail lamp illuminates and the buzzer sounds in the chosen modes:

• Trip - will trip when 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;
• Hold shows the breakdown voltage and the leakage current;
