Technical Data
The Fluke 1550B is a digital
megohmmeter capable of test-
ing switchgear, motors, genera-
tors and cables at up to 5000 V
dc. It can be used for a wide
range of tests: from simple spot
checks to timed tests and
breakdown tests. Measurement
storage and PC interface soft-
ware make it ideal for preven-
tive maintenance. Heavy-duty
leads, probes and alligator clips
fit in the custom carrying case,
for a rugged field testing kit.
•Standard test voltages of
250 V, 500 V, 1000 V,
2500 V and 5000 V
•Additional test voltages
available in 50 volt steps
from 250 to 1000 volts,
100 volt steps from 1000 to
5000 volts
•Measures up to 1 Tera-Ohm
•Warning voltage function
alerts the user that line volt-
age is present and gives the
voltage reading up to 600 V
ac or dc
•Automatic calculation of
Dielectric Absorption and
Polarization Index with no
setup
•Guard system eliminates
the effect of surface leakage
current on high-resistance
measurements
•Large digital/analog LCD
delivers detailed measure-
ment data
•Measures cable or insulation
capacitance
•Measures leakage current
•Ramp function (0-5000 V
dc) for breakdown testing
•99 minute timer for timed
tests
•Automatically stores test
data in up to 99 locations
that user can name for quick
recall later
•High-capacity rechargeable
batteries
•Includes Quicklink 1550B
Software and Optical
Interface cable for down-
loading to a Windows®PC
•Custom soft case for tester
and accessories
•Includes heavy-duty leads,
probes and alligator clips
•Two-year warranty

Specifications
Electrical specifications
The meter’s accuracy is specified for one year
after calibration at operating temperatures of 0
°C to 35 °C. For operating temperatures outside
the range (-20 °C to 0 °C and 35 °C to 50 °C),
add +/- .25 % per °C, except on the 20 % bands
add +/- 1 % per °C.
