Fluke Insulation Tester, 1000V Maximum Test Voltage, 600V Safety Category Voltage - 2491945

This insulation tester is a handheld digital instrument designed to combine insulation resistance testing with multimeter functions for maintenance and fault-finding in industrial and commercial electrical systems. It operates from AA batteries and is suitable for field use, offering insulation test voltages from low-voltage checks up to high-voltage diagnostics while providing protection against live circuits before initiation.

Features & Benefits

• Insulation test range to 2GΩ for high-resistance detection
• Test voltages from 50V to 1000V for versatile diagnostics
• 1mA nominal test current to limit stress on components
• CAT IV 600V and CAT III 1000V safety rating for site use
• Digital display with 6000-count backlight for clear readings
• Battery life approximately 1000 h enabling extended field use

Applications

• Suitable for preventative maintenance on motor windings and drives
• Ideal for insulation resistance checks on switchgear and panels
• Used for troubleshooting contaminated or moist insulation
• Suitable for commissioning tests on transformers and cables
• Can be used with VFD-driven equipment using low-pass filtering

What protects the instrument from testing live circuits?

The unit detects Terminal voltage above 30V and inhibits insulation tests to prevent inadvertent live testing.

How does the tester handle capacitive loads during measurements?

It auto-discharges capacitive voltage and is operable with capacitive loads up to 1 μF.

What environmental conditions will it tolerate during operation?

The instrument functions between −20 °C and 55 °C and is specified for non‑condensing humidity up to 95% at 10 °C–30 °C with reduced limits at higher temperatures.

Which approvals and safety standards apply to the device?

It meets CE and CSA approvals and conforms to IEC safety categories for measurement environments.

What accessories are provided for practical field use?

The supply includes a remote probe, test leads and crocodile clips Plus a hard carrying case and a K‑type thermocouple where fitted.
