The Megger BMM Series Multi-MEGGERS are a versatile range of hand-held insulation testers designed to extend the capability of insulation testers beyond anything available on the market today.
In addition to extremely high-sensitivity insulation resistance measurements (200 GΩ), these instruments offer complete multimeter testing capability and the ability to view the insulation measurement in terms of leakage current (µA). The top-of-the- range models also include data storage and download capability. The end user can now carry a single instrument to the test site rather than multiple instruments.
BMM2500: Top of the range contractor/service technician insulation tester and multimeter featuring result storage, printing, and downloading. Offers the same voltage ranges as the BMM2000.
BMM2580: Top of the range low voltage/specialty application insulation tester and multimeter. Features include result storage, printing, and downloading. Voltage ranges of 50, 100, 250, 500, and 1000 are also available in this model. Additionally, all units are supplied with the SP1 Remote Switch Probe as a standard accessory (at no additional cost) for hands-free operation. |

- 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 BMM2500 series provide the ideal mix of features for
the busy electrical contractor requiring the ultimate in
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 combined with the ever increasing need for
tracability of test results.
- The BMM2580 offers all the features of the 2500 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.
- 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 non-volatile memory, (NVM), 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. 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 PowerSuite for
Windows and NICEone. (for N.I.C.E.I.C. 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
almost endlessly including such items as temperature
probes, airspeed indicators and high current clampmeters
thus extending the scope of the BMM2500 series into key
industries such as heating and ventilation (HVAC), and
servicing.
