HT4022 - current tongs for the measurement TRMS of alternating current to 400A, AC/DC of stress, frequency, resistance, electrical conductivity, active reactive, total power, and also capacity rate, energy, cosj, harmonic of voltage and current beside one and three phase networks, the turning of phases with the aid of one wire. Before the cover can be established the probe, which makes it possible to conduct measurements by one hand. [ZHKD] of four sign (10000 units) with the illumination makes it possible to work before the rigid weather conditions. Instrument completely corresponds to the standards: EN 61010-1, CATIII 600V.

Basic functions

• the measurement Of true RMS
• alternating current to 400 A
• the voltage of alternating current out of 600[V]
• DC voltage out of 600[V]
• resistance to 2000W
• the measurement of frequency with the aid of the probe or by tongs down 400[Gts]
• phase displacement, phase sequence
• active, reactive and total power beside one and the three-phase networks
• active, reactive and total energy beside one and the three-phase networks
• the coeff. of power, cosj beside one and the three-phase networks
• measurement to 25 harmonics of voltage and current with THD%
• the test of the electro-ProfDNawn
• [avtoranzhirovanie], illumination, the disconnection of nourishment, the retention of the measurement
• measurement MAX/MIN/AVG, the peaks Of pEAK[s] with the duration of 1m[sek]
• the indication of discharging the small batteries
