The Benning installation tester IT105 enables you to carry out a simple and efficient safety test on electrical systems after installation, modification or as a regular repeat test in accordance with VDE0100 / 0105.
The installation tester is very easy to use: all measuring functions can be selected directly using the rotary switch. The large graphic display (95 x 55 mm) with backlighting makes operation easier and is very easy to read even in dark environments.
The Benning IT 105 has an AUTO start function for low-resistance, loop and line impedance measurements as well as a LOCK function for continuous measurements of the insulation resistance. The measuring process can be started directly using the test button on the test probe.
Measurement functions:
- Low resistance of protective conductor and equipotential bonding connections (test current: 200 mA)
- Insulation resistance with test voltage of 250 V, 500 V and 1000 V
- Loop impedance (L-PE) without FI / RCD tripping (NO-TRIP) with simultaneous display of the fault current (PFC)
- Line impedance (LN / L) with high test current (HIGH CURRENT) with simultaneous display of short-circuit current (PSC)
- Testing of RCDs, standard and delayed (S) with sinusoidal (AC) and pulsating test current (A)
- Automatic measurement of the tripping time (½ x, 1 x and 5 x IΔN) and the tripping current using the ramp method
- Voltage and frequency measurement up to 440 V.
- Three-phase direction test in three-phase networks (L1-L2-L3)
