Digital Insulation / Continuity Tester
• 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.
