| www.csua.berkeley.edu/~turin/question.html What are the accuracy and criterion a measuring device must have over the instrument it is measuring? For example: I have flow controllers that range from 20sccm to 10,000sccm +/- 1 % of setpoint (standard cubic centimeter minute) I want to find a device that can be used to verify the performance of the flow controllers. |
