Bar graph to display insulation resistance
- Bar graph to display insulation resistance
- Displays the value of external AC voltage with flashing symbol
- Auto null function to automatically subtract the test lead resistance before displaying the real continuity resistance value
- Live circuit warning buzzer
- Releasing the test button automatically discharges the charges stored in the circuit under test
- 200mA measuring current on continuity testing
