ETCR Insulation Resistance Meter ETCR3500 Anti‑Interference

Description

Product Overview

The ETCR3500 is a portable insulation resistance meter designed for demanding electrical testing environments. It features a full‑color touchscreen that shows real‑time test data, history records, and system status at a glance. Built with unique anti‑interference technology, the unit delivers stable results on large distributed capacitance sites such as long cables and in strong electromagnetic fields like substations. Core measurement functions include insulation resistance (IR), polarization index (PI), dielectric absorption ratio (DAR), step, ramp, and both AC/DC voltage testing. The device also offers customizable test modes, user‑defined voltage and duration settings, and optional PI/DAR calculation formulas to meet specific site requirements.

Usage

Ideal for electrical contractors, maintenance engineers, and utility technicians, the ETCR3500 excels in field inspections, substation maintenance, and cable testing. Its automatic voltage monitor halts testing if live voltage exceeds 36 V, safeguarding both operator and equipment. The built‑in current and temperature monitors provide continuous feedback, while the automatic discharge function quickly releases residual charge after each test, eliminating the need for external discharge circuits. Data can be stored locally—up to 1,000 test records with timestamps—and transferred via USB for detailed analysis on a computer.
