ETCR

ETCR 3500 5KV High Voltage Insulation Tester Megohm Meter 5T 5mA electrical system tool

SKU CH-85RP-28253

Tests insulation up to 5 kV with IR, PI, DAR, STEP and RAMP modes, plus live-voltage monitoring that blocks testing above 36 V

  • Touchscreen shows live data and history for fast decisions
  • Anti-interference tech keeps readings stable on long cables and in substations
  • Five insulation tests plus AC/DC voltage in one instrument
  • Custom voltage, duration and formula settings match site requirements
  • Auto voltage guard stops testing above 36 V to protect user and meter

5 kV Insulation Tester for High-Voltage Assets

The ETCR 3500 is a 5 kV insulation resistance tester built for cables, motors, transformers and switchgear. It performs IR, PI, DAR, STEP, RAMP and AC/DC voltage measurements on a single touch screen. Designed for engineers who need comprehensive diagnostic data in one handheld instrument.

Touch-Screen Setup With Live-Voltage Lockout

A colour touchscreen shows test parameters and history records on the same display, reducing menu navigation. The unit monitors live voltage on the device under test and automatically blocks testing when voltage exceeds 36 V, protecting both operator and instrument. Automatic discharge releases stored charge after each test without external circuitry.

Anti-Interference Stability In Substation

Unique anti-interference technology maintains stable readings on long cables with high distributed capacitance and in strong electromagnetic fields such as substations. Internal temperature and humidity monitoring plus real-time test-circuit current display support consistent performance during extended test sequences. Custom voltage and duration settings adapt to specific site requirements.

Questions about this item

How can I verify the ETCR 3500 is working correctly after setup?

Run a self-check using the touch colour screen; the display shows live circuit current, internal temperature and humidity, and will block a test if live voltage exceeds 36 V.

What comes in the box and what must I buy separately?

The tester ships with test leads and a charger; no additional accessories are required for IR, PI, DAR, STEP, RAMP or AC/DC voltage measurements.

Which test voltage setting should I choose for my application?

Select a custom test voltage on the touch screen to match the insulation class of the cable, motor, transformer or switchgear under test.
