It is suitable for testing gas tubes, carbon gaps, MOVs, Zener and avalanche diodes, and thyristor devices.
It uses a precise 1 mA detector; when 1 mA is conducted through clamping type devices, it removes the test voltage and displays the reading.
The tester offers a linear voltage ramp selectable for 200 V/s or 1000 V/s operation.
The product comes with a 2-year warranty.
