Insulation Testers

Performs insulation resistance testing at 500V and 1000V, and resistance measurements up to 1000Ω. Megohm log scale graduated from 0.1 to 1000MΩ. Ohm scale is linear with a range from 0 to 10Ω. Can be used for a broad range of plant and field service applications and is designed for use in harsh environments.

Measures insulation resistance to 4000GΩ (4TΩ). Test results include DAR, PI, capacitance, voltage measurement, and duration of test. Memory function enables storage of test results. RS-232 interface allows connection to a computer running DataView^® for configuring the instrument and downloading test results and generating reports.

Displays test voltage, insulation resistance, and leakage current during the test; and capacitance and discharge voltage present at the test leads at the conclusion of the test. Features include automatic calculation and presentation of the Dielectric Absorption Ratio (DAR) and Polarization Index (PI).
