DB231 LCR Component
Capacitor Tester Bridge
|
|
|
DB231 LCR Component Capacitor Tester is specially
designed for manual as well as automatic high accuracy and high-speed
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.
|
DB231 LCR Component Capacitor Tester
|
The DB231 LCR Component
Capacitor Tester
is well suited for
mounting on sorting machines for ceramic capacitors or other automatic
applications where the distance between the front
panel of the DB231 and the Jig is less than 40cm.
When the distance is longer, the DB230 should be preferred to provide maximum accuracy.
The DB231 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 DB231 LCR Component Capacitor
Tester in the version MCR in order
to have the test cables connected to the rear panel only.
Optional protection box
PB10. For further protecting of the instrument against charged
capacitors.
