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 analog arc which incorporates the benefits of electronic analog indication and unambiguous digital readings. The analog 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.

Ranges & Accuracy

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 analog arc which incorporates the benefits of electronic analog indication and unambiguous digital readings. The analog 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 m½ 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.
