Setup: The Setup Mode is used to perform
functions such as:

Probe Diameter Calibration

Setting Probe Force

Changing Display Resolution

Adjusting Beeper Volume

Setting the Printer to Continuous Mode.
Press the Setup Key to step through the
functions. When the desired function is activated
use the function keys to change the settings and
the F5 Key to accept the changes.
Probe Diameter Calibration: This is the normal mode for calibrating the probe diameter using the Calibration
Block supplied with the tool. If the Probe Symbol is Flashing in the upper left corner of the Display, it will be
necessary to Calibrate the Probe Diameter.
Important: The Altissimo will store the Calibrated Probe Diameter even after it is turned off. The Probe Diameter
must be recalibrated when the Altissimo is first received and periodically thereafter, especially when measuring
conditions change or the Probe is changed or repositioned.
Press the SETUP Key and the Probe Calibration Mode Icon will light. The Display will prompt for Point 1 (Cal 1).
Position the Calibration Block under the Probe. Using the Coarse Adjuster Knob move the probe down onto the
Upper Measuring Surface until the tool beeps. Move the Probe clear of the surface. The display prompts for Point 2
(Cal 2). Similarly measure the Lower Measuring Surface of the Calibration Block. Measure the Upper and Lower
Measuring Surface a second time.
Note: The first and second measurements must be taken in opposite directions, the third and fourth measurements
must also be taken in opposite directions. (See Figure 28) If the display does not increment from Cal 3 to Cal 4, then
take the next Point must be taken in the opposite direction.
Accept the Calibration - After measuring each surface twice, the Altissimo will display a number which is the
Deviation of the Probe Calibration. The deviation is the repeatability of the points taken during Probe Calibration.
This provides a measure of the quality of the measurements. If the Deviation is sufficiently low, under .0002"
(.004mm), then Press the F5 Key (

) to accept the value. (See Figure 29) If the Deviation is high, over .0002"
(.004mm), then check the tightness of the Probe Arm and Probe. Check the cleanliness of the Probe Tip and
Calibration Block. Make sure that the Probe and Belt Locks are fully unlocked. Then recalibrate the Probe.
Clearing Probe Calibration: Pressing the CLEAR key while the Probe Calibration Symbol is on will clear the
Probe Calibration.
