Nice review Jakeman! I've got a lot to learn with regards to calibration, and people such as yourself help make it a possibility. Thanks for the comprehensive post.

Please correct me if I am wrong. Did I understand you to say that there is an upcoming firmware upgrade that will extend the 600's range to 5Hz? If this is correct, do you have any idea when this will be available?
