Megger LCB2000/2 User Manual

LCB2000/2 and LCB2500/2
Premium Loop & Circuit Breaker Testers
DESCRIPTION
The Megger
®
LCB2000/2, and LCB2500/2 series of Loop
and Circuit Breaker testers utilise advanced microprocessor
technology to provide a host of new features not normally
associated with standard testers.
The instruments utilise a large custom LCD display with a
power saving LED backlight. The display is mounted
behind a highly resilient polycarbonate window where it
provides outstanding clarity and viewing angle.
Both the LCB2000/2 and the LCB2500/2 are designed to
perform all the live system tests required for an electrical
installation meet in full the requirements of the 16th
Edition Wiring Regulations, (BS 7671). By providing a
range of both basic and advanced features, all of which
are simple to use, the LCB2000/2 and LCB2500/2 are
designed for maximum user convenience and time saving.
As an example the auto-sequence RCD test enables the
instrument to perform and record all the necessary tests on
an RCD in sequence whilst the user stays at the
distribution board to reset the trip.
In the event that the installed system has a fault or does
not test as expected a host of diagnostic features such as
ramp RCD tests are on hand to pinpoint the problem.
The LCB2500/2 provides the ultimate in technology
offering the ideal mix of features for the busy electrical
contractor combined with speed of operation, live display
of R1 + R2 values 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 requirement for traceability of test results.
The LCB2500/2 offers comprehensive data storage options
with individual test results being quickly stored with
relevant connection details against user selectable
distribution board and circuit references. 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 the simple download of stored data
from the instrument into files on a PC. 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. Instrument
setups and printer language may also be changed.
Where creation of certificates of test is required both
instruments are fully compatible with PowerSuite for
Windows, PowerSuite XPress and NICEone (for the
creation of N.I.C.E.I.C. Certification alone).
