CALIBRATION
CS NONE NONE -- Saves the calibration and all parameters
CF NONE NONE Frequency
Set Optimal Full Scale – Sets Frequency and
Optimal Coil Current – sensor must be positioned
at max displacement from sensor. This is the first
thing done in a calibration.
CZ NONE NONE --
Sets Zero and sets gains and offsets (Executed
after CF) – sensor must be positioned at the
minimum displacement from sensor. This is the
second thing done in a calibration
CP x NONE X = 0-20 AD Reading
Cal Point (0-20) for piecewise linearization –
sensor must be positioned at the correct percent of
full scale – i.e. 0=0%, 1=5%,2 =10% … 20=100% -
- direction (min to max or max to min) does not
matter as long as it changes monotonically. For 6
point polynomial cals only use 0-5 points and they
must be spaced 20% apart ... i.e. pt 0 is 20%, pt1
is 40% ... pt 5 = 100% of range. For a 2 point cal
pt 0 = 0% pt 1 = 100%.
CD NONE NONE Status
Completes the 21 point calibration and sets up the
tables for operation
C6 NONE NONE Status Completes the 6 point polynomial cal
C2 NONE NONE Status Completes the 2 point linear cal
CAZ NONE NONE -- Cal Adjust zero point
CAM NONE NONE -- Cal Adjust mid point
CAF NONE NONE -- Cal Adjust full scale point
CAD NONE NONE Status Complete 2 Point Adjust
CT 0 NONE NONE -- Collect Temp Comp Data for D1T1
CT 1 NONE NONE -- Collect Temp Comp Data for D1T2
CT 2 NONE NONE -- Collect Temp Comp Data for D2T1
CT 3 NONE NONE -- Collect Temp Comp Data for D2T2
CT 4 NONE NONE Status Completes Temperature Compensation for Sensor
CT 5 NONE NONE Status
Completes Temperature Compensation for
Electronics
