Fluke 1577 Insulation Multimeter: New Generation Replaces Fluke 1507

The Fluke 1577 replaces the older Fluke 1507 in the Milano insulation range. Where the legacy meter combined insulation testing with only a basic voltage readout, the 1577 adds a complete True RMS digital multimeter section, so a technician can trend insulation resistance and then verify voltage, current, resistance and continuity without changing instruments.

Accuracy is the core of the change. The 1577 holds 0.09% DC accuracy and a 6000 count display, allowing readings to be compared directly against calibrated loop signals. Test voltages from 50 V to 1000 V and an insulation range to 600 MOhm let teams follow the same test procedure across low voltage control circuits and medium voltage motors, where the older 1507 forced a second instrument and a second record sheet.

What Changes Against the Legacy Model

ParameterFluke 1507Fluke 1577 Insulation Multimeter
Measurement scopeInsulation test plus basic voltage onlyInsulation test plus full True RMS voltage, current, resistance, continuity
Display resolution3.5 digit insulation readout6000 count dual readout with analog bar graph
Safety ratingCAT III 600 V / CAT IV 300 VCAT III 1000 V / CAT IV 600 V
Diagnostic ratiosNot availablePolarization index and dielectric absorption ratio on board

Key Features

  • One instrument replaces two: insulation tester plus a full digital multimeter in a single housing
  • 0.09% DC accuracy gives readings that stand up to calibration checks on transmitters and panels
  • Five insulation test voltages from 50 V to 1000 V cover motors, cables, switchgear and low voltage control circuits
  • Polarization index and dielectric absorption ratio calculated automatically for predictive maintenance records
  • Remote test probe allows one-handed insulation testing on installed cable runs
  • CAT III 1000 V and CAT IV 600 V rating covers distribution panels and service entrances

Typical Applications

  • Motor and pump insulation trending in water and wastewater plants
  • Cable and switchgear insulation checks before energising new installations
  • Field verification of 4-20 mA loops after transmitter replacement
  • Annual preventive maintenance routines on oil and gas terminal equipment

Ordering and Support

Orders are handled together with Milano transmitters, gas detectors and explosion proof robots, so insulation testers, multimeters and loop instruments can ship on one commercial invoice. Spare fuses, test leads and the remote probe are available as separate line items for maintenance stores.
