LCR CAPACITOR BRIDGE TEST SET
DB234 LCR Capacitor Component Tester

DB234 LCR Component Tester is especially designed for high accuracy testing of capacitors on production lines, not least for integration with sorting machines in a production environment. 
The instrument is reliable, user-friendly and easy to set up to any test.
The DB234 LCR Component Tester utilizes an external bridge module allowing the user to install the measuring bridge very close to the measuring Jig. This ensures high measuring accuracy. 
Especially when measuring at 100kHz or 200kHz 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.



DB234 LCR Component Tester

  • With the DB234, total cable length of
    up to 3m (118 inches) is supplied.
  • The DB234 utilizes a well-proven input 
    protection system to protect the bridge
    module from damages owing to
    exposure to charged capacitors.
  • This secures that the DB234 does not
    break down as easily as other LCR bridges, 
    when exposed to charged capacitors.

The DB234 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 200kHz. 
As standard, it 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.
