The DB233 LCR Component Bridge Tester is specially designed for manual as well as
automatic high-speed high accuracy testing of capacitors or other LCR
applications. The instrument is reliable, user-friendly and easy to
set up to any test application on production lines, in quality control
departments or in laboratories.

DB233 LCR Component Bridge Tester
|
The DB233
LCR Component Bridge is well suited for mounting on sorting machines or other automatic test
applications
where the distance between the front
panel of the DB233 and the Jig is less than 50cm.
When the distance is longer, the DB232
should be preferred to provide maximum accuracy.
The DB233
LCR Component Bridge performs
capacitance and loss factor tests at any of the
4 standard frequencies.
Dual, triple and quadro frequency tests are
popular to give an immediate presentation of
capacitance and loss factor measurements
over a range of frequencies.

As standard the
instrument has a built-in comparator for deviation measurements,
IEEE488 (GPIB) and RS232C data interfaces as well as handler interface
(opto-coupler type) with 12+4 bins for production sorting. The
high-speed data interfaces may be used for an external computer in
order to control the system, or for collection of data for statistics
and analysis.
Bin sorting with up to
12 bins for capacitance for 1st frequency and up to 4 bins
for tan d using 2nd frequency. Or tan d may be measured at
several frequencies using the 4 bins for different levels of the
dissipation factor.
|
The
standard fitted PCMCIA card is the smart way of storing set-ups.
Fail-safe loading of set-ups to several instruments will be done fast
and efficient.
The
test cables are as standard connected to the front panel of the
instrument.
Another possibility is to order the DB233 in the version MCR in order to have the test cables connected to the rear panel only.
Optional
protection box PB10 protecting the instrument against charged
capacitors is available.
