DB230 LCR Component Tester
|
This ensures high measuring accuracy.
Especially when measuring at
100kHz and 1MHz, cables are main
causes to
noise.
When installing an LCR bridge on a production
line, some distance
between the instrument
and the Jig is unavoidable.
With the DB230, total cable length of up to
4 m (157 inches) is supplied.

The DB230 LCR Component
Tester utilizes a
well-proven input protection system to protect the bridge module from
damages owing to exposure to charged capacitors. This secures that the
DB230 does not break down as easily as other LCR bridges, when exposed
to charged capacitors.
The DB230 LCR Component
Tester can perform
dual frequency tests at any combination of frequencies.
A popular configuration is to test capacitance at 1kHz and loss factor
at 100kHz or 1MHz.
As standard, DB230 LCR Component Tester can sort capacitors into bins according to the
measured parameters at two frequencies simultaneously.
|
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.
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).
All measured data are collectable from the data interfaces.
Via the
PCMCIA slot it possible to easily store set-ups to distribute to other
instruments quickly, without operator mistakes.
