High Voltage Insulation Testers & Megohmmeters
Fluke 1537 Insulation Resistance Tester & Megohmmeter
The Fluke 1537 Insulation Resistance Tester & Megohmmeter is an advanced, lightweight, portable ohmmeter with an intuitive interface. It delivers fast, accurate, reliable AC/DC voltage and resistance measurements. The Fluke 1537 designed to simplify frontline troubleshooting on industrial equipment or solar installations.
Selectable Test Voltage
Test an eclectic variety of equipment and systems by adjusting the test voltage from 250 V to 2500 V in 100 V increments.
Additionally, the Fluke 1537 Insulation Resistance Tester & Megohmmeter supports customisable testing parameters allowing you to:
- Set user-defined labels
- Adjust test duration
- Store results
Data can be downloaded and managed using the supplied PC software.
Extended Insulation Resistance Measurement
Capable of measuring insulation resistance up to 500GΩ, the Fluke 1537 Insulation Resistance Tester & Megohmmeter can analyse a range of instruments, small circuits, and high-voltage installations.
Furthermore, a short circuit current up to 5mA means the Fluke 1537 Insulation Resistance Tester & Megohmmeter provides faster, more stable resistance measurements.
Automatic PI & DAR Calculations
To improve reliability, the Fluke 1537 Insulation Resistance Tester & Megohmmeter automatically calculates the Polarisation Index (PI) and Dielectric Absorption Ratio (DAR), which minimises the influence of environmental factors on the insulation performance.
Troubleshooting Features
Automatic calculation of the dielectric discharge rate (DD) makes identifying elusive insulation issues easier. Moreover, the Ramp Test mode, which linearly increases the applied test voltage by 100 V/s, helps you to find hard-to-identify fault conditions.
Continuity Indicator
Continuity is indicated visually and audibly for maximum convenience, enabling uninterrupted testing.
High Measurement Capacity
The Fluke 1537 Insulation Resistance Tester & Megohmmeter can administer up to 1300 measurements at 2500 V or 6500 measurements at 250V, improving job efficiency and productivity.
Enhanced Safety Features
Optimised for safety, the Fluke 1537 Insulation Resistance Tester & Megohmmeter has a CAT IV 600V safety rating and a voltage alarm function.
An enhanced, ergonomic, easy-to-use ohmmeter, the Fluke 1537 Insulation Resistance Tester & Megohmmeter provides rapid, reliable resistance measurements regardless of the system type or environment.
