Safety-related tests of electrical installations after construction, modification or as periodic inspection can be carried out easily and efficiently by means of the installation tester.

• unbeatable price/performance ratio
• easy operation, all measuring functions can be selected directly by means of a rotary switch

Features:

• extra large graphic display (95 x 55 mm) with background lighting
• test probe with TEST key for starting the measuring process
• AUTO start function for low-impedance, loop and line impedance measurements
• LOCK function (permanent measurement) of the insulating resistance
• compensation (null balance) of the der measuring lines up to 10 Ω
• supplied in a hard-top case, test probe with „TEST“ key, set of measuring leads/ alligator clips, test cable with shock-proof plug, carrying strap, 6 x 1.5 V batteries (IEC LR6/ type AA) and calibration certificate

Measuring functions:

• low-impedance resistance of protective conductor and equipotential bonding conductor connections (testing current: 200 mA)
• insulating resistance with testing voltages of 250 V, 500 V and 1000 V
• loop impedance (L-PE) without RCD tripping (NO-TRIP) with simultaneous display of the fault current (PFC)
• line impedance (L-N/L) with high testing current (HIGH CURRENT) with simultaneous display of the short-circuit current (PSC)
• testing of RCDs, standard and delayed (S) with sinusoidal (AC) and pulsating testing current (A)
• automatic measurement of the tripping time (½ x, 1 x und 5 x IΔN) and the tripping current using the ramp method
• voltage and frequency measurement up to 440 V
• phase sequence testing in three-phase mains (L1-L2-L3)
