The number of points is configured in parameter FACTORY_CURVE_LENGTH, being in the
maximum 5 points. The entry points will be configured in the FACTORY_CURVE_X and of output in
the FACTORY_CURVE_Y.
The Parameter FACTORY_CURVE_BYPASS controls the enabling/disabling of the curve and has
the following options:
x
"Disable ",
x
"Enable and Backup Cal " ,
x
"Disable and Restore Cal " ,
x
"Disable or Allows to enter the points"
To configure the points of the curve, the option "Disable or Allows to enter the points” must be
chosen. Then press the "Characterization Cal". The following message appears: "This Function
alters XMTR characteristics. Proceed? Y/N". To proceed, select "Yes". A new message appears: "Is
XMTR connected to accurate pressure standard ?". To proceed, select "Yes". Apply the desired
pressure and wait that the same one stabilizes. If the pressure is not stable, select "No-read again".
If it is stable, enter "Yes" and then, type the applied pressure P1. Repeat this procedure for the next
point P2. After that, if the user wants to configure more points, just repeat this procedure up to 5
points. If not, just select "No" for the question “Do you want to configure more points? ".
After configuring the points, the user needs to qualify the curve. The option "Enable and backup
cal", enables the curve and save the calibration settings. The option "Disable and restore the cal",
disables the curve and restores the calibration settings. The option “Disable”, just disables the curve
and does not take care about the calibration settings.
