The insertion or the modification of the points is to be made on the channel ac-
tive at this time, by the RS232-C Com (See corresponding remote commands
COR, LCOR and NCOR). Once calibrated, the led COR is highlighted. By si-
multaneous measurement with 2 probes (Cha 1-2 ou Cha 1+2) the LED is acti-
vated only if both channels have a correction.
The entry of the points has to comply with the following conditions:
•
The numbering of the points must be continuous and must start from the
point number 0 or 1 (if the point 0 is not introduced, it will automatically be
created with a value at zero).
•
After each point, the plunger of the probe must always be moved from the
outside to the inside position.
•
The correction value is limited to 1mm or 0.1 inch.
•
The difference of correction between 2 consecutive points is limited to the
half of the distance between these 2 points. Example: for 2 points with
1mm distance from each other, the difference of correction between these
2 points cannot be bigger than 0.5mm
•
The unit must be switched on the channel 1 or 2 (key Fct).
•
The unit must be in high resolution mode !
If one of the above condition is not observed, the correction point will not be
saved and the error message Err5 (function not allowed) will be shown.
How to introduce a point by point correction :
1.
Prepare a set of gauge blocks or an appropriate calibration instrument.
2.
Set the unit into the following modes: High resolution (key Resol) Positive
measuring direction (key +/-) Relative measuring mode (key Rel/Abs)
3.
Set the probe to a reference value and zero it (key Preset). This value cor-
responds to the pre-travel of the probe (0.8mm).
4.
Set the probe's plunger on the first gauge block or calibration value.
5.
Read the displayed value.
6.
Enter the first correction value with the remote command COR 1/ +/-x.
yyyyy. The value to enter corresponds to the value of the gauge block less
the readen value on the display (take the sign + or – into account).
7.
Repeat the points 4 to 6 for the other gauge blocks or calibration values.
8.
After the entering of the last point, activate the correction curve with the
remote command COR ON.
The SYL -Calibre software facilitates the introduction of the point by point correc-
tions (available on request)
