General Description - Megger BMM2500 Guide De L'utilisateur

The MEGGER ® BMM2500 Series instruments are
battery powered Insulation and Continuity testers,
with a measurement capability from 0,01Ω
Continuity to 200GΩ Insulation.
Offering multi-voltage facilities, the instruments
take full advantage of microprocessor technology
and feature a large liquid crystal display combining
digital and analogue readings. The analogue dis-
play has the benefit of indicating trends and fluctu-
ations in readings, while the digital readout gives
direct accurate results. The display is also backlit
giving clear visibility even in low light conditions.
The BMM2500 Series instruments have the unique
capability of being able to measure voltages down
to a resolution of 0,1mV. This gives the user the
option to fit a wide variety of transducers to further
enhance the capabilities of the BMM Series instru-
ments, eg temperature or humidity measurement.
A customised connector on the top of the instru-
ment enables the optional M E G G E R
Switched probe to be used for two handed probe
operation.

GENERAL DESCRIPTION

® S P 1
The 250V, 500V and 1000V ranges can be used to
test electrical installations in compliance with
BS7671 (16th Edition IEEE Wiring Regulations)
IEC364 and HD384, since each range has a 1mA
minimum test current at the minimum pass values
of insulation specified in these documents. The
100V range (BMM2580) is ideal for testing
telecommunications equipment which would be
damaged by higher voltages. The 50V range
(BMM2580) is useful for testing sensitive equip-
ment, such as electronic components, and com-
puter peripherals.
The BMM2500 series instruments have a current
facility which enables up to 500mA to be mea-
sured, this together with Ω, V and mV ranges
means that the instrument can realistically be used
in situations where previously a multimeter would
be needed. For higher currents an optional current
clamp is available.
