Calibration procedure (cont.)
•
For calibration using a 25 mm gauge height, send the CALi remote command (i= the number
of channel 1 to 4)
•
For calibration using any two gauge heights send the CALi remote command: Ref0, Ref1
(i = number of canal 1to 4 ; Ref0, Ref1 = gauge heights, normally Ref0 < Ref1)
•
After a few seconds the module returns REF0? and the corresponding probe LED flashes.
•
Position the probe on the first reference point and then press the foot switch or send the
CAL remote command. The probe LED flashes rapidly during the reading procedure.
•
After a few seconds the module returns REF1? and the corresponding probe LED flashes.
•
Position the probe on the second reference point and then press the foot switch or send the
CAL remote command. The probe LED flashes rapidly once more during the scan.
•
The module returns CALi OK and the new calibration is saved if the procedure is correct. If
the module returns CALi ERR, the calibration is not correct and it is not saved.
If a point by point correction was active while the module was being calibrated it is disabled but
not deleted.
4.3 Diameter measurement calibration
E
The module can be calibrated to measure internal diameters thanks to the CALi remote com-
mand: Ref0, Ref1. Use a small standard diameter like Ref0 and a large standard diameter like
Ref1. Once the calibration procedure is over enter the value of the small diameter in the Preset
function.
4.4 Pairing a probe and a conversion module
To increase the accuracy of the measurement it is possible to pair each module channel with its
corresponding probe. This operation is independent of calibration. It consists of defining a correc-
tion curve of no more than 26 points on the path of the probe and specifying a correction for each
point. This must be repeated for the other channels if necessary.
For an optimum result it is advisable to perform correction point by point when the module is in a
state of perfect thermal stabilisation, i.e. at least 2 hours after being powered
up. If the module is not thermally stabilised point by point correction is not possible. The module
returns TEMP .ERR.
