The HT Italia HT7051 was designed to perform professional insulation resistance measurements with test voltage programmable up to 5KV DC and also has a wide measurement range up to 10Tohm, allowing applications for industrial LV environments (tests on electrical machines, power transformers, electrical cables, switchboard panels, generic devices, etc…)
Three different function modes are available on the meter: FIX mode (fixed test voltage), ADJUST mode (programmable test voltage), and RAMP mode (programmable test voltage and duration time with up to three selectable ramps) which allows for 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 HT Italia HT7051 is powered by a NiMH rechargeable battery, also having an internal memory for saving results, and an RS-232 interface for connection to a PC to transfer the saved measurements. The instrument is housed in a portable, hard carrying case which assures safety when used as an “on field” meter.
