TECHNICAL DATA
Fluke 1587 FC/1577
Insulation Multimeters
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

Electromagnetic compatibility
International IEC 61326-1: Portable Electromag-

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.
