LCR bridge puts components on the line
Low-cost precision LCR bridge incorporates a full limits comparator designed for binning applications on electronics production lines.
TTi (Thurlby Thandar Instruments) has introduced a new version of the LCR400 low-cost precision LCR bridge incorporating a full limits comparator designed for binning applications on electronics production lines Up to eight pass bins and two fail bins can be defined, and binning can be used to sort different tolerances of the same value or multiple different values

LCR bridge sets new price-performance standard
The LCR400, new from TTi (Thurlby Thandar Instruments), is a precision LCR bridge with a built-in 4-terminal test fixture and a full limits comparator for component sorting.
LCR bridge takes on surface-mount components
The LCR400 precision LCR bridge is now available with high-quality four-terminal tweezers for measuring surface-mount components.
A numeric keyboard allows rapid setting up of binning values.
Nonvolatile memory is provided for the storage of up to nine complete instrument set-ups.
The LCR400 has a basic accuracy of 0.1% for inductance, capacitance and resistance measurements.
Three measurement frequencies are available between 100Hz and 10kHz.
The instrument is fully auto-ranging (with range hold) and can also automatically select the function based on the component inserted.
It has dual five-digit displays, the second of which is used for either the secondary parameters (Q or D) or for showing binning information.
For through-hole components, the unit has a built-in high-quality four-terminal test fixture that will accept most wire-ended components directly.
A pair of plug-in pillar adapters allows axial components, such as bandoliered resistors, to be measured directly without bending the wires.
The position of the test fixture on the instrument ensures that component bandoliers can be handled without interfering with the display or keyboard.
For surface-mount components, high-quality four-terminal tweezers are available.
The tweezers connect directly into the built-in test fixture of the LCR400, and four-terminal connection is made at the base of the gold-plated jaws only a few millimetres from the tip.
An external test fixture can also be used, and a capacitance null function allows up to 100pF to be nulled out.
A switchable bias voltage is provided for polarising electrolytic capacitors.
An RS232 interface is incorporated which allows connection to a PC and can be used to set up all measurement and sorting functions as well as store readings.
PC software is supplied which allows both setup and results logging.
The LCR400 costs GBP 638 (plus VAT).
