Fluke 1507 Insulation Resistance Tester

Product Summary:
The Fluke 1507 is a versatile, handheld insulation resistance tester tailored for electrical contractors and industrial/commercial electricians. It offers multiple test voltages (50 V to 1000 V), automatic PI/DAR calculations, and a Compare (Pass/Fail) function to streamline preventive maintenance and troubleshooting.

Key Features:

• Insulation tests from 0.01 MΩ to 10 GΩ

• Test voltages: 50 V, 100 V, 250 V, 500 V, 1000 V

• Automatic Polarization Index (PI) and Dielectric Absorption Ratio (DAR)

• Compare (Pass/Fail) mode for repetitive tests

• Live‑circuit detection to inhibit tests above 30 V

• Auto‑discharge of capacitive voltage for user protection

• Measures AC/DC voltage (0.1 V–600 V) and resistance (0.01 Ω–20 kΩ)

• Lo‑ohms earth‑bond continuity (200 mA)

• Remote probe support for hard‑to‑reach tests

• Large backlit display and auto power‑off

• CAT IV 600 V overvoltage rating

Applications:

• Preventative maintenance of motors, cables, and transformers

• Commissioning and acceptance testing

• Troubleshooting insulation failures in switchgear

• Earth‑bond continuity checks

• On‑site field service in industrial and commercial facilities

Product Benefits:

• Speeds up repetitive tests with Compare (Pass/Fail) mode

• Ensures safety with live‑circuit detection and auto‑discharge

• Covers wide insulation range up to 10 GΩ for diverse equipment

• Compact, rugged design for field portability

• Remote probe option reduces time and labor on hard‑to‑access targets

FAQs:

Q. What voltages can the Fluke 1507 apply for insulation tests?
It supports 50 V, 100 V, 250 V, 500 V, and 1000 V test voltages to suit a variety of insulation materials and equipment.


Q. How does the Compare (Pass/Fail) function work?
Set a reference insulation resistance threshold; the tester then indicates Pass or Fail during subsequent tests, speeding up repetitive checks.


Q. Can I test live circuits with the Fluke 1507?
No—live‑circuit detection prevents testing if voltage above 30 V is present, protecting the tester and the user.
