Establish a reference for the measurement
A measurement reference should be established prior to conducting
measurements. Measurement references can be established by
calibrating channels or presetting dimensions.
Calibrating channels using the Master function
Channel calibrations are performed using the Master function. A
single-point calibration defines the reference value of the absolute
datum (D0) of an input channel. A full calibration defines the reference
value of the absolute datum, and the resolution of the channel input.
Since encoders have fixed resolutions based on etched scales or
some other permanent device characteristic, typically only a single
point is calibrated to define a reference position. Transducers such as
LVDT and Half-bridge devices do not have fixed resolutions. The use
of these devices requires calibrating both ends of the transducer’s
measurement range to derive resolution. Once a full calibration has
been performed, single-point calibrations can be performed as
required to define new measurement reference positions.

An input calibration is applied to any parts that use that
channel in a formula. For example, a channel calibration
performed for channel 1 and part number 0 will also apply
to any other parts using channel 1.
