DESCRIPTION
The Megger
®
BMM2000 series of Insulation Multimeters
utilise advanced microprocessor technology to provide a
host of new features not normally associated with standard
insulation and continuity testers.
The instruments utilise a large backlit LCD display
incorporating a patented analogue arc which incorporates
the benefits of electronic analogue indication and
unambiguous digital readings. The analogue scale
provides rapid identification of insulation condition
highlighting any variable readings and is complemented by
the precision and simplicity of the digital display.
The BMM2000 provides the ideal mix of features for the
electrical contractor requiring the top performance and
functionality but without the need for data storage and
download.
The instrument features three insulation test voltage
ranges, (250 V 500 V and 1000 V), each of which is
,
capable of supplying 1 mA test current at the minimum
pass levels expressed by BS 7671, IEC364, HD38 and
VDE0413 Parts 1 and 4. Insulation measurements
extending up to 20 GΩ may be made (200 GΩ BMM2080)
A live circuit warning is included to guard against
inadvertent connection of the instrument to a live supply.
Voltage in excess of 25 V will trigger the warning
indicator.
A hands free 200 mA continuity test range meeting the
requirements of European legislation is also included to
ensure the accurate measurement of ring circuit final
conductors and primary and supplementary bonding. The
range has a facility to null the resistance of the test leads
ensuring that the measurement displayed is due entirely to
the conductors under test. A continuity buzzer is
incorporated and sounds when resistance’s below
approximately 5
Ω
are encountered.
The insulation and continuity ranges are augmented by a
number of features only to be found on a dedicated
multimeter. The BMM2000 series includes autoranging
voltage measurement up to 500 V a.c./d.c., resistance
measurement from as low as 10 mΩ up to 10 MΩ and
current measurement from 10 mA to 500 mA. Higher
currents still may be measured using an external mV
output current clamp such as the optional Megger MCC10
By incorporating all the above features into a single unit
the BMM2000 series remove the need to carry a separate
multimeter.
The BMM2080 offers all the feature of the 2000 but with
the addition of 100 V and 50 V insulation ranges and a 10
uF capacitance range. These additional features make the
instrument ideally suited for applications in the telecom
industry.
The BMM2000 series has been designed to withstand the
day to day handling and storage of a toolbag environment
and comes complete with a three year warranty.
Both instruments feature mV ranges enabling connection
of any transducer with a mV output. Such devices extend
BMM2000 SERIES
Premium Insulation Multimeters
the range of possible measurements almost endlessly including such items as temperature probes, airspeed indicators and
high current clampmeters thus extending the scope of the BMM2000 series into key industries such as Heating and
ventilation (HVAC), and Servicing.
ELECTRICAL CONTRACTORS
The BMM2000 series insulation multimeters has a wide variety of applications and is ideal for testing electrical
installations to both the British and the International Wiring Regulations. Each instrument conforms to the requirements
of Table 71A in BS7671 and to VDE 0413 parts 1 and 4, HD 384, IEC 364 and EN 5117. In addition the range meets the
requirements of BSEN 61010-1 for safe connection to a 440V Installation Category III supply.
The BMM2000 series Insulation Multimeters are designed to provide the electrical contractor with a highly functional tool
for testing/commissioning fixed installations.
Where certificates of test are required data may be manually entered onto the forms or manually entered into certification
software such as PowerSuite for Windows™ or NICEone to create a professional certificates with the tracability necessary
for safety critical applications. The inclusion of a power saving backlight ensures that the display can be clearly seen even
where the distribution board is located in a dark cupboard but without ruining battery life.
Three insulation test voltages of 250, 500 and 1000 V are provided to ensure that the correct test voltage for the
installation under test is always available. The 500 V range is suitable for the majority of testing on circuits with a
nominal voltage up to 500 V The 250 V insulation range is necessary where low voltage circuits supplied by an isolating
.
transformer are tested whilst the 1000 V range is used for circuits with a nominal voltage exceeding 500 V and below
1000 V An additional leakage facility allows any insulation measurement to be displayed in terms of microampere
.
leakage currents.
The instruments have a 200 mA continuity range which is ideal for testing the continuity of ring final circuit conductors,
primary bonding of services and of supplementary bonding conductors. The zero offset adjustment allows the resistance
of the test leads to be ignored so the measurement shown is due to the conductors under test only.
The feature set of the BMM2000 series extends to include measurement ranges for voltage, current, resistance enabling
one instrument to be used where normally a separate multimeter would be called for.
To aid operation in awkward situations where the instrument cannot be held in one hand the Megger SP1 switched
probe is included to facilitate control of the instrument test button directly from the probe.
In addition to the electrical features above the rugged design of the BMM2000 range ensures that they can withstand the
everyday handling, transportation and storage with other tools in the contractors toolbag and is supplied with a three
year manufacturer’s warranty.
SERVICING AND HVAC
The BMM2000 series are ideal tools for the service industry since they offer a comprehensive range of features addressing
the requirements of the service engineer in a single unit.
The insulation ranges are useful for establishing the integrity of the internal parts such as motors, timers and transformers
whilst the continuity range can verify the correct earth bonding of the case metalwork and checking the operation of
switches etc.
The multimeter functions of Voltage, Current and Resistance find a multitude of uses in the measurement of component
parts within consumer appliances such as the verification of correct mains supplies timer switching characteristics and
component level measurements on control PCB’s.
The unique mV transducer input ranges enable the BMM2000 series to interface to a vast range of transducers for
measurement of the various parameters necessary during servicing and in the commissioning and verification of HVAC
systems. Temperature measurement is one of the most important additions for the service industry enabling the correct
operation of items such as oven thermostats or the measurement of heated air temperature and humidity to be made.
To further assist in servicing situations higher currents, (up to 10 A a.c.), may be measured by connecting the optional
Megger MCC10 current clamp. This enables measurements of appliance element/motor currents etc to be made quickly
and safety without interrupting the conductors.
TELECOMMUNICATIONS
In addition to the standard installation testing functions the BMM2080 includes additional 50 V and 100 V insulation
testing facilities and a 10 uF capacitance range. The low voltage insulation tests are necessary for the testing of delicate
components and equipment found in telecom systems which would be damaged by higher voltages.
The instruments are designed to perform tests on systems with up to 25 V of electrical interference or crosstalk without
the accuracy or reliability of results being effected and with no damage to the instrument.
