The Kyoritsu 3005A Digital Insulation and Continuity Tester uses a bargraph to display insulation resistance and displays the value of AC voltage along with a flashing symbol.

Features

Bargraph to display insulation resistance
Displays the value of external AC voltage along with flashing symbol
Auto null function to automatically subtract the test lead resistance before displaying the real continuity resistance value
Live circuit warning beeper
Releasing the test button automatically discharges the charges stored in the circuit under test
200mA continuity measuring current to IEC 61557
Minimum 1mA current on insulation tests to IEC 61557
