Introduction
The Fluke 1535/1537/1537-II Insulation Testers (the Tester or Product) are high-
voltage insulation testers to validate general circuits, such as switchgear, motors,
and cables.
The Tester features:
• Large liquid crystal display (LCD)
• Preset test voltages: 250 V, 500 V, 1000 V, 2500 V
• Insulation measurement: 200 kΩ to 500 GΩ
• Polarization Index (PI) measurement
• Dielectric Absorption Ratio (DAR) measurement
• Auto power o after 10 minutes of inactivity
The 1537/1537-II also includes:
• V ac/V dc/Resistance measurement
• Programmable test voltages: 250 V to 2500 V in 100 V steps
• Dielectric Discharge (DD) measurement
• Ramp mode that linearly increases (100 V/s) the applied test voltage
• Test timer and storage for test results with user-dened ID tag
• Breakdown voltage indication
• Mini USB serial port for download of test data
• PC software
