The High-Performance 2-in-1 Insulation DMM
The Fluke 1587 FC and 1577 Insulation Multimeters combine a
digital insulation tester with a full-featured, true-rms digital multi-
meter 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 accu-
rate 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 (sold separately)
* Two-year additional warranty offer may be discontinued without notice

Electromagnetic compatibility
International IEC 61326-1: Portable Electromag-
netic Environment; IEC 61326-2-2 CISPR 11:
Group 1, Class A
Group 1: Equipment has intentionally generated and/or uses conductively-coupled radio
frequency energy that is necessary for the internal function of the equipment itself.
Class A: Equipment is suitable for use in all establishments other than domestic and
those directly connected to a low-voltage power supply network that supplies buildings
used for domestic purposes. There may be potential difficulties in ensuring electromag-
netic compatibility in other environments due to conducted and radiated disturbances.
Emissions that exceed the levels required by CISPR 11 can occur when the equipment is
connected to a test object. The equipment may not meet the immunity requirements of
this standard when test leads and/or test probes are connected.
