CALIB FAIL - the density calibration has failed. There are several reasons for this condition:
• Not in measuring mode
• The 2 points are too close
• The 2 points fail a plausibility check
Normally a 1 point calibration is adequate for most density calibrations e.g. tailoring the densi-
ty to the new installation.
The 1 point calibration can be done twice, with two different products to achieve a 2 point cali-
bration. However, this is not recommended as there is no guarantee that the first point
entered will not be moved when the second point is entered.
2 Point Calibration
This is when the user wants to enter 2 set points.
The 2 point calibration makes sure that the 2 points entered by the user are used.
Warning - 2 point calibration will restore the factory calibration data before calibrating the 1st
point.
If first point has not been done, options will be as per “1 point calibration”
If first point has been calibrated, you must first select whether to proceed with 2nd point, make
the 1st point again, or break. Options are then as before.
Manual
If a manual calibration is selected, Point 1 density type DCF1 is dislayed. Press
g
to step to the
next DCF option or and to edit. After the last DCF, you will be asked to save data or
break.
