Fluke 1587/I400 FC Insulation Tester Multimeter Kit with AC Current Clamp

Comprehensive Insulation Testing + DMM Functionality

The Fluke 1587/I400 FC Insulation Multimeter Kit delivers a powerful two-in-one diagnostic solution. Built around the trusted 1587 FC insulation tester / digital multimeter, and bundled with the i400 AC current clamp, this kit is designed for electricians and maintenance technicians who need both insulation resistance testing and current measurement — without carrying separate instruments.

Performance & Diagnostic Versatility

The 1587 FC portion offers insulation testing from 0.01 MΩ up to 2 GΩ at selectable voltages (50, 100, 250, 500, 1000 V), making it suitable for motors, switchgear, cables, and more. It also functions as a full True-RMS multimeter: AC/DC voltage to 1000 V, AC/DC current (mA), resistance, continuity, capacitance, frequency, temperature, diode tests — giving full coverage for troubleshooting and preventive maintenance tasks.

Paired with the i400 clamp, the kit adds AC current measurement up to 400 A without needing to break the circuit — ideal for load testing, motor-start current assessment, or verifying current draw under real load.

Key Features:

• Dual-function: insulation tester + True-RMS digital multimeter in one compact handheld unit.

• Insulation resistance range: 0.01 MΩ to 2 GΩ with selectable test voltages up to 1000 V.

• Full multimeter capabilities: AC/DC voltage up to 1000 V, resistance, continuity, capacitance, frequency, temperature, and mA current measurement.

• i400 AC current clamp: measures 1 A to 400 A AC safely without breaking the circuit, suitable for large conductors (up to 32 mm).

• Ideal for motor inspections, switchgear maintenance, cable troubleshooting, preventive maintenance, and insulation integrity testing
