LCR COMPONENT 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.

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.
