The Benning IT 120B is a digital installation multifuction tester, which is capable of a full range of electrical testing and can perform insulation resistance tests, loop impedance tests - with or without tripping of the RCD. The loop impedance function on the Benning IT 120B is unlike most other multifunction testers as it can perform this test even without tripping of a 10mA RCD under normal conditions.

Additionally the Benning IT 120B will undertake RCD testing, including trip current and trip time tests, plus phase sequence/rotation and ground resistance tests. The Benning IT 120B is an advanced multifunction electrical installation tester with a host of built in features, to make it a valuable addition to testing electrical installations and circuits.

A large illuminated graphic display makes this particular unit user friendly, and the built in connection diagram assists in ensuring correct connections are made for testing. The built in help function makes this an easy to use device, and the PASS/FAIL indication on the display makes the user's job easy and uncomplicated.

Features:

• Insulation resistance test voltages of 100V, 250V, 500V and 1000V.
• Loop impedance and line impedance (optional non-trip of RCD), with calculation of short circuit current (PSC/PFC)
• Complete testing of residual current device (RCD).
• Measurement of contact voltage (without tripping), tripping time and tripping current of RCD.
• Phase rotation sequence testing in three phase mains.
• Voltage measurement up to 500V and online voltage monitoring.
• Measurement of protective conductor and equipotential bonding with 200mA test current.
• All measuring functions easily selected by means of a rotary switch.
• Switchable probe tip for releasing the measuring process.
• Graphic display and help function with connection diagram.
• Complete measuring result with measuring parameters, limiting value and symbols for PASS/FAIL.
• Earthing measurement by means of three-wire measuring method (requires optional earthing set)
• True RMS current measurement with current clamp adapter (optional).
• Illumination measurement by means of lux sensor (optional).
• Integrated measured value memory for 500 measurements.
• USB and RS-232 interface.
• Benning PC-Win IT 120 software included in delivery.
