Description
The NOVA multifunction instrument allows you to perform earth measurements using the 3 or 4-wire voltammetric method.
Suitable for all TT and TN systems, it also allows you to measure soil resistivity.
It allows you to test type A, AC and F differential circuit breakers up to 1A in General or Selective mode and type B, B+ and EV differential circuit breakers for testing electric charging stations (6mA AC or DC).
It has 4 modes to perform the differential test: RDC Time, RDC Ramp test, UC test for contact voltage and AUTO test.
Equipped with Ra (Loop) function for measuring global Earth resistance in TT systems. It also performs the high current LINE impedance test in order to obtain impedance values with two decimal places and to be able to calculate the prospective short circuit current.
It also performs insulation resistance measurement with test voltage from 50V-100V-250V-500V-1000V DC.
Furthermore, thanks to the EV CHECK adapter, it is possible to test the safety and functionality of electric vehicle charging cabins in a non-invasive way.
The shoulder strap allows for hands-free use while the optional remote probe allows for greater freedom of movement during measurements.
Includes EV-CHECK.
