Introduction
The Fluke 1550C and 1555 Insulation Testers (hereafter “the Tester”) are high-
voltage insulation testers to validate general circuits, such as switchgear,
motors, and cables.
The Tester features:
• Large liquid crystal display (LCD)
• Six preset test voltages: 250 V, 500 V, 1000 V, 2500 V, 5000 V, 10,000 V
(1555 only)
• Programmable test voltages: 250 V to 10,000 V (50/100 V steps)
• Resistance measurement: 200 kΩ to 2 TΩ
• Polarization Index (PI)
• Dielectric Absorption Ratio (DAR)
• Ramp mode that linearly increases (100 V/s) the applied test voltage
• Test timer and storage for test results with user-defined 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 Tester meets EN 61557 Parts 1 and 2; and EN 61010-1, CAT IV 600 V
Pollution Degree 2 standards. CAT IV equipment is designed to protect against
transients from the primary supply level, such as an electricity meter or an
overhead or underground utility service.
