, (contintred) A CHANNEL CALIBRATION is a complete check of the instrument loop and the sensor. This test verifies the channel responds to the measured parameter within the necessary range and accuracy. CHANNEL CALIBRATION leaves the chanr,c1 adjusted to account for instrument drifts between successive calibrations consistent with the plant specific setpoint methodology.
