The professional clip-on ammeter HT4022 offers you real effective value measurements (TRMS) for AC current up to 400 A and AC/DC voltage as well as resistance, continuity and frequency measurement. In addition, this model measures active power, reactive power, apparent power, power factor Cos φ and energy, both in single-phase as well as symmetrical three-phase systems, as well as the determination of phase rotation – with an innovative, patented method based on only one test tip. Thanks to the practical (also patented) rubber protective cap with plug-in device for a test tip, it is possible to take measurements quickly and easily with just one hand. Thanks to the large 4-digit LCD display (10000 points) with background lighting, a simple reading is guaranteed even under difficult conditions. The device corresponds to the specifications of EN 61010-1 in CAT III 600 V. Suitable for conductors up to max. 30 mm diameter.
