Calibrating the PCI-DDA08/12 

"In-system" calibration 

The PCI-DDA08/12 is calibrated at the factory for the correct voltages at the I/O connector. For more precise 
application of voltages at the "system end", we can provide a version of 

Insta

Cal that allows you to calibrate the 

board within your system for correct voltages at your field connection. This calibration lets you remove the 
effects of voltage drops caused by IR loss in the cable and connector for resistances up to 1 

Ω

. This calibration 

also allows you to zero out errors in any external signal conditioning up to approximately ±10 mV. 

In most applications, the version of 

Insta

Cal that ships with the board provides the accuracy specified. If your 

application has unusual requirements, such as long cables, etc., you may need the "in-system version" to 
achieve this accuracy. 

Contact technical support by phone, fax, or e-mail for details regarding the "in-system" calibration feature. For 
international customers, contact your local distributor where you purchased the board.
