LCR400 - Precision LCR Bridge / presný RCL meter - mostík

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 production 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 adaptors 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 meter. 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.

Full Component Sorting
The LCR400 provides comprehensive facilities for sorting components into ‘Bins’ according to value. The binning parameters 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 limits can be sequential or overlapping from a single nominal or can be based around different nominals.

Automated Control
The LCR400 incorporates non-volatile memory for up to nine complete instrument set-ups.
An RS-232 interface allows control to be exercised from a PC enabling the remote storage of set-ups and remote logging of results.
