Where to Go for Support

The National Instruments Web site is your complete resource for technical 
support. At 

ni.com/support

 you have access to everything from 

troubleshooting and application development self-help resources to email 
and phone assistance from NI Application Engineers.

A Declaration of Conformity (DoC) is our claim of compliance with the 
Council of the European Communities using the manufacturer’s 
declaration of conformity. This system affords the user protection for 
electronic compatibility (EMC) and product safety. You can obtain the DoC 
for your product by visiting 

ni.com/certification

. If your product 

supports calibration, you can obtain the calibration certificate for your 
product at 

ni.com/calibration

.
