test objects can be determined by measuring current and voltage using
integrated measuring instruments.
Thanks to its small size and low weight, the HV Tester is portable and
can be used directly on site. The clear arrangement of controls and
displays makes the set comfortable to handle.
The set has an integrated rechargeable battery.
A special protective ground circuit ensures a high level of safety.
