Fluke 1508 Insulation Tester
Introduction:
The Fluke model 1508 is a battery-powered insulation tester (hereafter, \”the Tester\”). This Tester meet CAT IV IEC 61010 standards. The IEC 61010 standard defines four measurement categories (CAT I to IV) based on the magnitude of danger from transient impulses. CAT IV Testers are designed to protect against transients from the primary supply level (overhead or underground utility
service).
The Tester measures or tests the following:
- AC / DC Voltage
- Earth-Bond Resistance
- Insulation Resistance
