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:

Resistance

Maximum Voltage Applied to any Terminal 600 V ac rms or dc
Storage Temperature -40 °C to 60 °C
Operating Temperature -20 °C to 55 °C
Temperature Coefficient 0.05 x (specified accuracy) per °C for temperatures <18 °C or >28 °C
Relative Humidity Noncondensing

0 % to 95 % @ 10 °C to 30 °C

0 % to 75 % @ 30 °C to 40 °C

0 % to 40 % @ 40 °C to 55 °C

Vibration Random, 2 g, 5-500 Hz per MIL-PRF-28800F, Class 2 instrument
