Description
The Fluke 1503 Insulation Resistance Meter is a rugged, compact, and highly reliable insulation tester designed for electrical professionals, technicians, and maintenance teams. It delivers accurate insulation resistance measurements and essential electrical diagnostics in a portable form factor, making it perfect for troubleshooting, commissioning, and preventive maintenance in residential, commercial, and light industrial applications
The Fluke 1503 is a battery-operated digital insulation resistance tester that helps you check the condition and integrity of electrical insulation. It is built to handle the most common insulation testing tasks with ease, offering test voltages of 500 V and 1000 V, a wide insulation resistance range, and additional measurement modes for resistance and voltage. Its ergonomic design and simple user interface make it ideal for field use and everyday testing needs.
✔ Wide Insulation Resistance Testing Range
• Measures insulation resistance from 0.01 MΩ to 2000 MΩ, enabling you to assess insulation quality across various cables, motors, transformers, and electrical components effectively.
✔ Dual Test Voltage – 500 V and 1000 V
• Offers two selectable test voltages, giving flexibility for different insulation testing requirements on low- and high-voltage equipment.
✔ Live Circuit Detection for Safety
• The tester detects live circuits and prevents insulation testing if AC/DC voltage exceeds 30 V, reducing the risk of unsafe tests.
✔ AC/DC Voltage Measurement
• Measures AC and DC voltage up to 600 V, helping you validate supply voltage before and after insulation testing.
✔ Earth Bond / Low-Ohm Resistance
• Capable of measuring earth-bond or low resistance values from 0.01 Ω to 20.00 kΩ, which is useful for continuity and grounding checks.
✔ Remote Probe Included
• Comes with a remote test probe, making repetitive testing easier, especially on hard-to-reach terminals or large equipment.
✔ Large Backlit Display
• The clear backlit LCD makes readings easy to view even in dimly lit environments.
✔ Portable & Robust Design
• Compact and lightweight, powered by four AA batteries that enable over 1000 insulation tests, the meter is ideal for onsite work.
✔ High Safety Category
• Built to meet CAT IV 600 V safety standards, making it suitable for testing at distribution and service entry points.
Q1: What is insulation resistance testing and why is it important?
Insulation resistance testing measures the resistance of electrical insulation to help identify degradation, moisture ingress, or faults. Low insulation resistance can lead to equipment failure, electrical leakage, or safety hazards. Testing ensures reliability and safety of electrical systems.
Q2: Can the Fluke 1503 measure live circuits?
It can measure AC/DC voltage up to 600 V, but the insulation test function will not start if voltage exceeds 30 V to protect the user and equipment.
Q3: How many tests can the Fluke 1503 perform on one set of batteries?
Powered by four AA alkaline batteries, it can perform at least 1000 insulation tests, making it suitable for extended field use.
Q4: Is this meter suitable for industrial environments?
Yes — with a CAT IV 600 V rating, it’s designed for high safety and can be used in demanding environments at electrical distribution points and industrial panels.
Q5: Can I use this meter for cable insulation testing?
Absolutely — this tester is ideal for checking insulation resistance on cables, motors, switchgear, and other electrical components.
The Fluke 1503 Insulation Resistance Meter is a dependable, professional-grade tool that combines precision, safety, and ease of use for all your insulation testing needs. Whether you’re an electrician, technician, or maintenance professional, this meter delivers trusted performance for preventive maintenance and troubleshooting — backed by Fluke’s legendary reliability.
