BMM2000 Series

Premium Insulation Multimeters

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
