Technical Data

Two powerful tools in one.

The Fluke 1587 and 1577 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.

Like other tools that you have come to expect from Fluke,

the 1587 and 1577 are rugged, reliable and easy to use.

Whether you work on motors, generators, cables or

switch-gear, the Fluke 1587/1577 Insulation Multimeters are

ideally suited to help you with your tasks.

• Large display with backlight

• Insulation test (1587: 0.01 MΩ to 2 GΩ) (1577: 0.1 MΩ to

600 MΩ)

• Insulation test voltages (1587: 50 V, 100 V, 250 V, 500 V,

1000 V),(1577: 500 V, 1000 V) for many applications

• Live circuit detection prevents insulation test if voltage

> 30 V is detected for added user protection

• Auto-discharge of capacitive voltage for added user

protection

• AC/DC voltage, DC milliVolts, AC/DC milliamps,

Resistance (Ω), Continuity

• Filter for motor drive measurements (1587 only)

• Capacitance, diode test, temperature, Min/Max, frequency

(Hz) (1587 only)

• Auto power off to save battery power

• CAT III 1000 V, CAT IV 600 V measurement category

• Included accessories: Remote probe, test leads and probes,

alligator clips, (K-type thermocouple, 1587 only)

• Accepts optional Fluke TPAK™ magnetic hanging system

to free your hands for other work

• Rugged, utility hard case allows you to bring everything

you need for the job

• Three-year warranty
