3. Quickly press and release the CALIBRATE pushbutton twice within one second or apply
two momentary signals to the external CAL terminal. The display alternates CAL and
Pnt1.
4. Wait for the display to change to CAL and Pnt2 then place a sample of the part present
condition in front of the probe face and press and release the CALIBRATE pushbutton or
apply a momentary signal to the external CAL terminal.
5. If the calibration is successful, the display reverts to displaying the gauge signal and
calibration is complete.
6. If the material is too thick or if the thickness measured at point 2 is very near to the
thickness measured at point 1, the display alternates showing Lo and diFF. To recover
from this condition, follow steps 6 or 7 below.
7. Restart calibration by placing a sample of the “part missing” condition before the probe
and press the CALIBRATE pushbutton once or apply a momentary signal to the CAL
terminal. Go to step 3.
8. Wait 30 seconds and the DS600 reverts to its previous state of gauging.
The gauging threshold is computed as an offset from the first point value in the direction of the
second point value. The size of the offset is computed as a percentage of the distance from the
first point to the second. The threshold computation is:
Threshold = Pnt1 - (Pnt2 - Pnt1) x Tol/100
The tolerance (Tol), expressed in percent, may be adjusted through the front panel as
parameter toL. The default value is 15%.
3.6 Calibration Save and Recall
After successful calibration, the DS600 saves the calibration in non-volatile memory. Model
DS600 saves only one calibration dataset. Model DS600P can save up to eight different
calibrations, and model DS600PC can save up to 64 different calibrations. Where multiple
calibrations can be saved, each saved calibration must be uniquely identified for later retrieval.
The identifier is in the form of a number ranging from 1 to 8 for the DS600P and from 1 to 64 for
the DS600PC.
The DS600P calibration identifier (1-8) may be specified through the front panel SEL parameter
or through the signals applied to the SEL2 through SEL0 and ENABLE terminals (See Table 4).
Whenever the ENABLE signal is asserted (ON), the selected calibration is determined by the
signals applied to the SEL2 through SEL0 terminals. When ENABLE is not asserted (OFF), the
selected calibration is determined by the last memory address entered through the front panel
SEL parameter.
