Description
Unbeatable in price and performance.
Safety tests on electrical systems after installation, modification or regular repeat testing can be carried out easily and efficiently with the BENNING IT 105.
Product benefits
- Simple operation, all measuring functions selectable via rotary switch
- Extra large screen (95 x 55 mm) with backlight
- AUTO-start function for low impedance, loop and line impedance measurement
- LOCK function (continuous measurement) of insulation resistance
- Compensation (zero adjustment) of the measuring leads up to 10 Ohm
- Comes in rugged hard case, test probe with TEST button, test probe/crocodile clamp set, test lead with safety plug, shoulder strap, 6 x 1.5 V mignon batteries and calibration certificate
Measurement functions:- Low-impedance resistance of protective conductor and equipotential bonding conductor 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 fault current (PFC)
- Line impedance (L-N/L) with high test current (HIGH CURRENT) with simultaneous display of short-circuit current (PSC)
- Testing of FI/RCD circuit breakers, 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 I?N) and the tripping current in ramp mode
- Voltage and frequency measurement up to 440 V
- Additional field direction test in three-phase systems (L1-L2-L3)
