Insulation multimeters with result storage

April 2002 Maintenance, Test & Measurement, Calibration

The new Megger BMM2500 series of insulation multimeters is now available from Spescom MeasureGraph. These instruments offer a number of new features not normally associated with standard insulation and continuity testers. They have large backlit LCD displays incorporating a patented analog arc, which includes 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.

Intended to provide the ideal mix of features for the busy electrical contractor, the BMM2500 series offers performance and functionality combined with speed of operation and efficiency provided by the downloading of data. When combined with software certification the system provides a highly professional image for the contractor, especially in view of the ever-increasing need for traceability of test results.

The BMM2580 offers all the features of the BMM2500 but with the addition of 100 V and 50 V insulation ranges and a 10 µF capacitance range. These additional features make the instrument well suited for applications in the telecommunication industry.

Both instruments offer comprehensive data storage options with individual test results being stored against user selectable distribution board and circuit references. Alternatively, data logging may be selected and up to 300 consecutive measurements of any chosen parameter may be made at a selectable time interval. Data storage is contained within nonvolatile memory, ensuring that test results are not lost in the event of battery failure or removal. Once stored, results may be recalled to the display, printed to an external serial printer or downloaded to suitable software.

AVO Download Manager for Windows is included, enabling language changes to be performed, along with the simple download of stored data from the instrument into comma separated variable files. These files can be maintained as a record, used for manually completing certificates or exported to other applications such as spreadsheets and word processor documents. Where creation of certificates of test is required both instruments are fully compatible with AVO PowerSuite for Windows and AVO NICE one (for NICEIC Certification alone).

Both instruments feature special mV ranges enabling connection of a wide variety of mV output transducers. Such devices extend the range of possible measurements significantly, including such items as temperature probes, airspeed indicators and high current clampmeters thus extending the scope of the M2500 series into key industries such as heating and ventilation (HVAC), and servicing.
