sensor calibration
you read a temp, is it 'real' ?
what is the purpose of calibration ?
- many certs state "in spec", but this info while welcome is not useful
what is needed is a calibration curve indicating the sensor/instrument's deviation
the first graph is an air cal of 2 RTDs and 2 TCs, the second a liquid cal of 3 RTDs;
note that the yellow RTD is the same in both
(this was the delay Joe)
