LCR REMOTE CONTROLLED BRIDGE

CT10R LCR Bridge is a fast and accurate LCR Bridge offering the Component Manufacturers the speed, accuracy and reliability required to test and sort a wide spectrum of passive components. 
The CT10R LCR Bridge is in particular well-suited for use in a remote controlled, integrated test system.
The instrument has IEEE 488 and RS232C interfaces as standard and is fully controllable in "Talker/Listener" mode.

A control program on a floppy disk for an standard PC is included. Up to 9 limits on the primary (for instance C) and one limit on the secondary parameter (for instance tand) can easily be programmed.

CT10R LCR Remote Controlled Bridge

• Limit outputs for binning are open 
  collectors (relay or lamp drivers) 
  with a positive-common protection rail.
• Four BNC sockets on the front panel will 
  accept up to 1.5 meter long interconnections 
  to an external 4-terminal test fixture, JIG20, 
  can be supplied.
• The CT10R is an attractive, cost-saving solution 
  for automatic production lines and is supplied in 
  a 19" cabinet for rack  mounting.
• Sockets for IEEE and RS232C are located on 
  the rear panel and for easy access an extra RS232C socket are mounted on the front panel.
• Several CT10Rs can be networked with a single 
  controller.

Reliability and Serviceability
The CT10R Bridge is microprocessor-controlled which, among other advantages, makes the instrument self calibrating. Besides that, the reference components in the bridge circuit are extremely stable with respect to long-term drift.

Effective Input Protection
The CT10R Bridge is equipped with an effective input protection of 2 Joule up to 0.6V, i.e. 100V at 400 mF, and 500V at 16mF or 600V at 10mF.
If such a capacitor by accident has not been discharged before reaching the test fixture, no damage to the CT10R will occur. Consequently a costly production stop can be avoided.

Why is High Accuracy so Important?
If you are producing components with ±1%tolerance using bridge with 0.25 accuracy, you will have to set the limits to ±0.75% in order to compensate for the measuring error. Consequently your production line will reject some components, which actually are within the specifications. 
The CT10R has an accuracy of 0.05% over the main range.
This means that you can set your limits to±0.95% and reduce the loss of non-faulty components considerably.

Test Fixture
A 4-terminal (Kelvin) test fixture JIG20 can be supplied in case that the CT10R should be used as a bench instrument.
The 4-terminal test fixture will effectively cancel all errors due to contact resistance and connecting cable impedance.
The JIG20 has gold plated contacts, and up to 1.5 meter long cables can be connected between the test fixture and the CT10R without any deterioration of the accuracy.
