Multifunction TRUE RMS Installation Tester for Safety Testing on Electrical Installations

Top price and performance:

• testing according to IEC 60364-6 and EN 50110
• easy operation for efficient testing
• delivery including case, measuring leads, set of test probe/ crocodile clips, storage batteries, charging cable and calibration record

Features:

• unambiguous "PASS" / "FAIL" indication by means of green / red LED
• all measuring functions can be selected directly by means of a rotary switch
• graphic display with background lighting, help function with connecting diagram
• power supply by means of six NiMH storage batteries (AA)
• device with integrated storage battery charging function

Measuring functions:

• low-impedance resistance of protective conductor and equipotential bonding conductor connections (testing current: 200 mA with polarity reversal)
• insulating resistance with testing voltages of 50 / 100 / 250 / 500 / 1000 V
• line impedance (L-N / L) with voltage drop and short-circuit current
• loop impedance (L-PE) without RCD tripping and short-circuit current
• testing of RCDs types AC, A, F with contact voltage, tripping time and tripping current (ramp test)
• TRUE RMS voltage, frequency and phase sequence test

Industrial environments requires TRUE RMS measuring instruments!

Non-linear loads arising e.g. from motor drives with adjustable speed, frequency converters or mains supply units for office equipment and LED lamps generate a reactive power in the mains. As a result, multimeters and current clamps working with the so-called averaging measuring method ("RMS") will display the measured values with reduced accuracy.

In many cases and particularly in industrial environments, it is therefore absolutely necessary to use state-of-the-art "TRUE RMS" measuring instruments. The "TRUE RMS" measuring method indicates the actual effective value of an alternating current correctly – irrespective of whether the signal waveform of the current is sinusoidal or distorted.
