The HT2055 model is composed by a station unit and a meter unit in way to perform step/contact voltage measurements on electrical installations (typical HV power station) with nominal test current up to 50A according to the international guidelines. Both units, initially synchronized in time and current, can perform an exact calculation of step and contact voltage applying the real test current measured by the station unit. A internal DSP filtering also perform the automatically compensation of the noise voltage disturb on the earth system. The instrument permits also the earth resistance measurement with 3-wire method and the ground resistivity with 4-wire Wenner method. All results can be saved inside internal memory of the meter unit and download to PC with supplied Windows dedicated software
