Fluke 1537 Advanced Insulation Tester

Fluke 1537 Advanced Insulation Tester provides portable, high-voltage insulation testing for field work, solar installations and routine electrical maintenance. It offers selectable test voltages of 250 V, 500 V, 1000 V and 2500 V, with insulation resistance measurements up to 500 GΩ. A short-circuit current greater than 5 mA supports faster and more stable measurements.

Built-in Polarisation Index and Dielectric Absorption Ratio calculations help users assess insulation without completing the calculations separately. The ramp test mode increases the applied voltage from 250 V to 2500 V in 100 V steps, helping users locate insulation faults. A dielectric discharge rate calculation, timed testing and adjustable test duration add further control for detailed testing.

Fluke 1537 Advanced Insulation Tester also measures AC voltage, DC voltage and resistance. Its visual and audible continuity indicator allows users to confirm continuity without constantly watching the display. Results can be stored, transferred through the supplied USB cable and managed using the downloadable PC software.

 

Key Benefits
  • Measures insulation resistance up to 500 GΩ for high-voltage testing tasks.
  • Provides four selectable test voltages to suit different insulation systems.
  • Uses a short-circuit current greater than 5 mA for faster, more stable readings.
  • Calculates Polarisation Index and Dielectric Absorption Ratio automatically.
  • Uses ramp testing to help identify possible insulation fault conditions.
  • Provides visual and audible continuity indication for easier testing without watching the screen.
  • Stores up to 1,300 measurements at 2500 V or 6,500 measurements at 250 V.
  • Transfers stored results through USB for review and management using PC software.
  • Includes adjustable test duration, user-defined labels and timed testing.
  • Warns when an energised circuit above 30 V is detected.

 

Common Applications

Fluke 1537 Advanced Insulation Tester is suitable for a range of testing, maintenance and inspection tasks, including:

  • Industrial electrical insulation testing
  • Commercial electrical maintenance
  • Solar installation testing
  • Routine electrical troubleshooting
  • High-voltage insulation resistance measurement
  • Polarisation Index and Dielectric Absorption Ratio testing
  • Ramp testing to help locate insulation faults
  • AC and DC voltage measurement
  • Resistance and continuity testing
  • Timed insulation testing and result recording

 

Why Choose This Model?

Compared with the Fluke 1535 2500V Insulation Tester, the Fluke 1537 adds AC/DC voltage and resistance measurements, ramp testing, timed testing, visual and audible continuity indication, USB transfer and PC software. It also provides a short-circuit current greater than 5 mA, compared with greater than 2 mA for the Fluke 1535.
