Insulation Tester \ MegOhmmeter with Test Voltage Programmable up to 5kVDC

The Insulation tester \ MegOhmmeter HT7051 was designed to perform professional insulation resistance measurements with test voltage programmable up to 5kVDC and wide measurement range up to 10Tohm which permits a large applications for each industrial LV environment ( test on electrical machines, power transformers, electrical cables, switchboard panels, generic devices, etc…). Three different function modes are available on meter: FIX mode ( fixed test voltage ), ADJUST mode ( programmable test voltage ) and RAMP mode ( programmable test voltage and duration time with up to 3 kind of selectable ramps ) which permits to reach correct results in each situation. The Polarization Index ( P.I ) and Dielectric Absorption Ratio ( D.A.R ) available features are duration tests which permits to define a good behaviour of the global insulation. The Insulation tester \ MegOhmmeter HT7051 is powered by a NiMH rechargeable battery with integrated adapter which permits to reach great performances during the measurements, it have a internal memory for saving results and a RS-232 interface for connection to PC and transfer saved measurements. All structure is fitted in a portable hard carrying case which assure safety typical of a “on field” Insulation tester \ MegOhmmeter
