HV System

The HV System utilizes a NX Pro Tester as an integral component of the overall system. The NX Pro Tester requires specific hardware and firmware to operate with the HV Expansion Unit.

NX Pro Software Requirements

When used in a HV System, the NX Pro Tester requires different firmware than when used as a stand-alone unit. The firmware is differentiated by the first major number. “2” is for stand-alone operation and “12” for HV Systems.
