Watch out

  • The 1587 FC and the older 1587 look similar; the FC adds Fluke Connect wireless and the PI/DAR app functions.
  • Kits include the same meter plus clamps or accessories.
  • The 1577 is the lower-cost insulation multimeter (500 V, 1 GΩ) without Fluke Connect.

Why people pick it

  • Combines a full multimeter and an insulation tester up to 1 kV and 2 GΩ, so you carry one tool for both jobs
  • Fluke Connect sends readings, PI/DAR results and trends to a phone or the cloud, keeping you away from energized equipment
  • Live circuit detection blocks an insulation test above 30 V, and capacitive voltage auto-discharges in under half a second
  • CAT IV 600 V / CAT III 1000 V rating with 0.09% basic DC accuracy, per the spec sheet

Know before you buy

  • Current tops out at 400 mA; it is not a substitute for a clamp meter on high-current circuits
  • The 2 GΩ measurement range is only ±(10% + 3 counts) accurate at 1000 V; the tighter ±(1.5% + 5) spec applies below 600 MΩ
  • Fluke Connect Assets and the wireless sharing features add app and account overhead that occasional users may not want
