Fluke Insulation Tester, 500GΩ Insulation Testing Resistance, 2500V Maximum Test Voltage - FLUKE-1535

This insulation tester is a portable handheld diagnostic instrument designed for field and workshop insulation resistance assessment across industrial and renewable-energy settings. It delivers selectable test voltages from 250V to 2500V and measures very high resistance values to assist technicians in verifying insulation integrity and locating degradation on electrical assets.

Features & Benefits

• Selectable voltages 250–2500V for tailored testing ranges
• Insulation measurement capability up to 500GΩ for high‑resistance detection
• Short‑circuit current up to 5mA for faster, stable readings
• CAT IV 600V safety rating for use near incoming supply points
• AA battery operation enabling long field use without mains power
• LCD display for clear visualisation of measured values

Applications

• Suitable for insulation testing of motors and generators on site
• Ideal for commissioning and maintenance of solar installations
• Used for preventive maintenance in industrial electrical systems
• Can be used for troubleshooting insulation faults on factory equipment

How many measurements can I expect between battery changes?

Using AA alkaline cells, the unit can perform over 1,300 tests at the highest test voltage on a single set of batteries.

Are there functions to assist insulation condition analysis?

Yes. It calculates Polarisation Index and Dielectric Absorption Ratio automatically to reduce environmental influence on results.

What additional measurements does the Advanced variant offer?

The Advanced instrument provides AC/DC voltage and resistance measurements Plus adjustable test voltage in 100V steps and ramp test mode.

How does the instrument manage charged capacitive circuits?

Charging and discharging behaviour is specified

typical charge rate for capacitive loads is 5s/μF and discharge rate is 1.5s/μF.
