Fluke Insulation Tester, 1000V Maximum Test Voltage, 2GΩ Insulation Testing Resistance - FLK-1587FC/TPAK/C25


This insulation tester is a handheld, battery-powered instrument that combines insulation resistance measurement with multimeter functions for field diagnostics and preventive maintenance in industrial environments. It is designed for use on live and de-energised equipment, providing insulation resistance up to very high values and selectable test voltages to assess insulation condition under controlled test currents. The unit is suited to technicians working on motors, drives and electrical systems where portable, rugged measurement capability is required.

Features & Benefits


• Insulation range to 2GΩ for detecting high-resistance faults
• Test voltages selectable up to 1000V for versatile inspections
• Nominal test current 1mA to exercise insulation without overload
• Live-circuit inhibit prevents testing if greater than 30V present for safety
• Backlit 6000-count display for clear readings in low light
• Operates on AA batteries delivering around 1000 h of meter use

**Applications**


• Suitable for motor winding insulation assessment with VFDs
• Ideal for commissioning and preventive maintenance checks
• Used for troubleshooting insulation degradation on switchgear
• Can be used for asset baseline recording in industrial plants
• Suitable for on-site field testing of cables and installations

How does the instrument handle capacitive loads during insulation tests?


It is operable with capacitive loads up to 1 μF and auto-discharges capacitive voltage rapidly, with discharge time less than 0.5 s for C = 1 μF or less.

What environmental limits apply for onsite use?


The unit functions between -20 °C and 55 °C and can be stored between -40 °C and 60 °C

humidity limits vary with temperature up to 95% non‑condensing at 10 °C–30 °C.

What protection and safety categories does it meet?


It is rated for CAT III 1000V and CAT IV 600V measurement categories and meets IEC safety standards including IEC 61010 variants.

How is data handling supported for trend analysis and storage?


When used with compatible wireless tools and software it enables timed ratio tests, trend graphs, memory storage and temperature compensation via a measurements app.

What accessory options improve field usability?


Accessories include remote probe, test leads, crocodile clips, a magnetic hanger option and a soft case for site work.
