Fluke Insulation Tester, 2500V Maximum Test Voltage, 500GΩ Insulation Testing Resistance - FLUKE-1537

This insulation tester is a battery-powered instrument for assessing electrical insulation integrity in industrial and solar settings. It delivers selectable DC test voltages from 250 V to 2,500 V and measures insulation resistance up to 500 GΩ, enabling field diagnostics and on-site troubleshooting with an LCD display and portable form factor.

Features and Benefits:

• 250 V-2,500 V selectable output for versatile high-voltage testing
• Up to 500 GΩ measurement range for detecting high-resistance faults
• 5 mA short-circuit current for faster, stable resistance readings
• CAT IV 600 V safety rating with built-in voltage alarm for protection
• AA alkaline battery operation for convenient field power source
• Stores thousands of measurements to improve inspection productivity

Applications

• Suitable for commissioning and maintenance of solar arrays
• Used for testing insulation on industrial motor windings
• Ideal for diagnosing high-voltage cable insulation issues
• Can be used for periodic insulation surveys in plants
• Used with on-site data download for post-test analysis

What battery configuration powers the instrument and how many cells are required?

It runs from AA alkaline cells and requires eight cells to operate.

How does the instrument cope with varying environmental temperatures during field use?

It operates between -10 °C and 50 °C to accommodate common site conditions.

What standards and safety classifications apply to its measurement functions?

Measurement and general safety comply with IEC 61557-1 and IEC 61010-1, with pollution degree 2 rating.

How are dielectric absorption and insulation deterioration assessed automatically?

It computes Polarisation Index and Dielectric Absorption Ratio automatically to reduce environmental influence.

What additional measurement types are available beyond insulation resistance on the Advanced unit?

The Advanced variant can measure AC/DC voltage and resistance, and perform dielectric discharge rate calculations.
