HT Italia HT4020 True-Rms Clamp Meter 400A with Power Factor Measurement

HT Italia

HT Italia HT4020 TRMS AC Clamp Meter

HT4020 is a clamp meter that performs TRMS measurement of AC current up to 400A, AC/DC voltage, frequency, resistance and continuity. This model also perform measurements of Active, Reactive, Apparent power, Power Factor (cosj) and Energy, both in single phase and three phase systems and have a patented phase rotation measures with an innovative 1 wire method. Thanks to the practical rubber cap to be mounted on the jaws (patented also), it’s possible to hold test leads while measuring and have one hand free to work. The large 4 digit LCD display (10000 counts) with backlight permits an easy readability also in critical visual conditions. The instrument is complying with IEC/EN 61010-1, CAT III 600V and is ideal to solve typical problems occurring in industrial environments such as troubleshooting, non-linear loads, frequency driven motors, PCs.

Take extreme care of the following conditions while taking measurements with the HT Italia HT4020: 

  • Do not measure voltage or current in humid or wet environments. 
  • Do not use the clamp in the presence of explosive gas (material), combustible gas (material), steam or dust. 
  • Do not touch the circuit under test if no measurement is being taken; 
  • Do not touch exposed metal parts, unused terminals, circuits and so on; 
  • Do not use the instrument if it seems to be malfunctioning (i.e. if you notice deformations, breaks, leakage of substances, absence of segments on the display and so on); 
  • Be careful when you measure voltages exceeding 20V as you may risk electrical shocks. 
  • Take care not to allow your hand to pass over the safety guard (see Fig. 1, pos.2) on current measurements and voltage measurements using the holster.
