Hi I am currently reading the analogue inputs using the command and response mode but would like to be able to read the channels faster. I have looked into streaming mode and was just wondering if at this speed the labjacks accuracy is maintained especially when reading thermocouples in uV. Thanks

Speed does not effect accuracy. The only thing to watch for is that increased speed can expose settling errors if your source has too high of source impedance. I would not expect a problem with a thermocouple, but you can do a quick test. Scan an extra channel right before your thermocouple, and jumper that channel to GND or VS to see if it makes a difference whether you are settling from 0V or 5V.
