The high-performance 2-in-1 insulation DMM. The Fluke 1587 FC Insulation Multimeters combine a digital insulation tester with a full-featured, true-rms digital multimeter in a single compact, handheld unit, which provides maximum versatility for both troubleshooting and preventative maintenance. The Fluke 1587 FC Insulation Multimeter adds four powerful new diagnostic functions through the Fluke Connect® Measurements app: - PI/DAR timed ratio tests with TrendIt™ graphs identifies moisture and contaminated insulation problems faster - Memory storage through Fluke Connect eliminates writing down results, reduces errors and saves data for historical tracking over time -Temperature Compensation through app for establishing accurate baselines and relevant historical comparisons - Historical tracking and trending of assets identifies degradation over time, allows real-time decisions to be made in the field with Fluke Connect® Assets Product highlights - PI/DAR timed ratio tests - Live circuit detection prevents insulation test if voltage 30 V is detected for added user protection - VFD low-pass filter for accurate motor drive measurements - Auto-discharge of capacitive voltage for added user protection - Insulation test (1587 FC: 0.01 M? to 2 G?) - Insulation test voltages (1587 FC: 50 V, 100 V, 250 V, 500 V, 1000 V) for many applications - AC/DC voltage, DC millivolts, AC/DC milliamps, Resistance (?), Continuity - Capacitance, diode test, temperature, Min/Max, frequency (Hz) - Auto power off to save battery power - CAT III 1000 V, CAT IV 600 V measurement category - Large display with backlight - Rugged, utility hard case allows you to bring everything you need for the job - Included accessories: Remote probe, test leads and probes, alligator clips, K-type thermocouple - Accepts optional Fluke TPAK Magnetic Meter Hanger for convenient hands free operation - Three-year standard warranty; extendable to five-years through product registration within 45 days of purchase
