LCR400
LCR400 low-cost precision LCR bridge
Bridging the price-performance gap
Anyone who has tried to purchase a high accuracy meter for
LCR measurement at a reasonable cost will have discovered
the problem.
There are plenty of low cost hand-held LCR meters available,
but the accuracy is poor and the facilities very limited.
There are plenty of high performance LCR bridges available,
but the costs are typically an order of magnitude greater than
the simple hand-held units.
The LCR400 bridges the gap. It provides the performance and
facilities required for precision component measurement at a
price not far above that of a hand-held unit.
The LCR400 is a low-cost precision LCR bridge intended for
use within component inspection, laboratories and produc-
tion facilities. The basic measurement accuracy is 0.1% and
the maximum measurement frequency is 10kHz.
Designed for serious use
The LCR400 is housed in a rugged casing of sufficient weight to
stay where it is put.
It incorporates a high quality four terminal test fixture with adap-
tors for axial or radial components. The fixture is unobstructed
for ease of use with bandoliers.
Lower cost through innovative design
The LCR400 sets a new price standard for a high performance
LCR bridge. Advanced design techniques utilising the latest
component technologies have made this possible.
Now a precision component measurement system is within the
budget of every area of a company from the laboratory through
to goods-inward inspection.
Non-volatile set-ups
As well as remembering the last used set-up, the LCR400
incorporates non-volatile memory for up to nine complete in-
strument set-ups for rapid recall.
Automated results logging
An RS-232 interface is provided for linking to a PC. Optional
Windows based software (LCR-PCLink) is available which al-
lows results to be logged onto a PC (save to a file and to the
screen) and enables instrument set-ups to be saved and re-
stored.
Full component sorting
The LCR400 provides comprehensive facilities for sorting
components into ‘Bins’ according to value. The binning pa-
rameters can be defined from the keyboard of from a PC via
the RS-232 interface.
Up to eight pass bins and two fail bins can be defined. Bin lim-
its can be sequential or overlapping from a single nominal or
can be based around different nominals.
High quality test fixture
The LCR400 has a built-in four terminal sprung-jaw test fixture
with pillar adaptors making it suitable for use with both axial and
radial components.
Optional adaptors are also available to allow connection to ex-
ternal test fixtures.
Surface mount tweezers
High quality four terminal SMD tweezers are available as an op-
tion for measuring surface mount components.
The tweezers connect directly into the built-in test fixture of the
LCR400. Four terminal connection is made at the base of the
gold plated jaws only a few millimetres from the tip.
Alternative connection methods
An adaptor is available which converts the built-in test fixture
into a set of four BNC sockets. This can be used to connect the
LCR400 to external test fixtures or test lead sets.
TTi also offers a high quality Kelvin Clip test lead set suitable for
precision four terminal measurements.
