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.
