Description
The NOVA multifunction instrument allows you to perform earth measurements with the 3 or 4 wire Voltamperometric method.
Suitable for all TT and TN systems, it also allows you to measure the resistivity of the ground.
It allows you to test type A, AC and F differentials up to 1A in General or Selective mode and type B, B+ and EV differentials for testing electric charging stations (6mA AC or DC).
It has 4 modes for testing RCDs: RDC Time, RDC Ramp test, UC test for contact voltage and AUTO test.
Equipped with Ra (Loop) function for global Earth resistance measurement in TT systems. It also performs the LINE impedance test at high current 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 a test voltage of 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 you to use the instrument hands-free while the optional remote tip allows greater freedom of movement during measurements.
