AEMC Model 6505 Megohmmeter


SKU: 1A0320

Model: 6505 Megohmmeter

Part Number: 2130.18

Ordering Number: 1A0320


The Megohmmeter Model 6505 is a True Megohmmeter® portable instrument housed in a rugged field case that operates on either 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 the leakage current during the test. Capacitance of the sample and discharge voltage present at the test leads is displayed at the conclusion of the test.

The Model 6505 is designed with a high level of built-in safety features. This meter incorporates test inhibit capabilities which will not allow test voltages to be generated if a live sample is detected. The test terminals are recessed to ensure operating safety.
