case and operates on battery or line power. It performs voltage, insulation, and

capacitance measurements. This instrument contributes to the safety of electrical

installations and equipment.

Features include automatic calculation and presentation of the Dielectric

Absorption Ratio (DAR) and Polarization Index (PI). The Model 6505 displays

the test voltage, insulation resistance, and leakage current during the test.

Capacitance of the sample and discharge voltage present at the test leads is

displayed at the test’s conclusion.

The Model 6505 is designed with the highest level of built-in safety features. This

meter incorporates test inhibit capabilities that will not allow test voltages to be

generated if a live sample is detected. The test terminals are recessed to ensure

operating safety.

Features:

■Test voltage combination of 500V, 1000V, 2500V, and 5000V.
