Product Overview

The FLUKE-1587 FC CAL is an insulation multimeter. It is a single tool that allows users to perform advanced insulation testing for preventive and PdM tasks. This high performance 2-in-1 insulation DMM combines digital insulation tester with full featured, true-rms digital multimeter in a single compact, handheld unit which provides maximum versatility for both troubleshooting and preventative maintenance. It adds 4 powerful new diagnostic functions through Fluke Connect measurements app. The PI/DAR timed ratio tests with TrendIt graphs identifies moisture and contaminated insulation problems faster. Historical tracking and trending of assets identifies degradation over time, allows real time decisions to be made in field. It measures 600.0mV to 1000V AC voltage, 6.000V to 1000V DC voltage, DC millivolts, AC/DC milliamps, 600.0 ohm to 50.0Mohm resistance, continuity, 1000nF to 9999μF capacitance, diode test, -40 to 537°C temperature, min/max, 99.99Hz to 99.99KHz frequency (Hz).
