Introduction
The Fluke 1550B MegOhmMeter (hereafter "the Meter") is a high voltage
insulation tester for testing general circuits, including switchgear, motors, and
cables.
The Meter has the following features:
⇒ Large liquid crystal display (LCD) with text display
⇒ Five pre-set test voltage: 250 V, 500 V, 1000 V, 2500 V, and 5000 V
⇒ Programmable test voltage: 250 V to 5000 V (50/100 V steps)
⇒ Resistance measurement: 0 Ω to 1 TΩ
⇒ Polarization Index (PI) measurement
⇒ Dielectric Absorption Ratio (DAR) measurement
⇒ Ramp mode that linearly increases (100 V/s) the applied test voltage
⇒ Test timer and storage for test results with user settable ID tag
⇒ Breakdown voltage indication
⇒ Rechargeable lead-acid battery
⇒ Auto shutoff after 30 minutes of inactivity
⇒ Infrared (IR) port for downloading test data
⇒ PC software supplied
The Meter meets EN 61557 Parts 1 and 2; and EN 61010-1, CAT III 600 V
Pollution Degree 2 standards. CAT III equipment is designed to protect against
transients in equipment in fixed-equipment installations, such as distribution
panels and lighting systems in large buildings.
