Calibration Mode

You only need to calibrate the instrument if the measurement performance is in question, if it has

been dropped or if it received an excessive jarring. A calibration is completed by measuring a

variety of patches on the calibration card.

NOTE: Make sure you use the calibration card that was supplied with the instrument for

calibrating. Do not substitute a calibration card from another instrument. The serial number on

the card should match the cal plaque number displayed in the Info screen.

Calibrating the Instrument

1. From the Main screen, use the Navigation Ring to move the highlight focus to the Calibration

icon.

or (“X” on the graphic indicates a verification failure)

the Exit icon.

3. Activate targeting mode by pressing the Measure button; or press the Select button while

the Begin Arrow icon is highlighted.

4. Remove the calibration card from its envelope and position the instrument’s target window on

the white patch. Use the reticule icon in the display screen for positioning. Make sure the

entire instrument is positioned on the calibration card as shown below.

calibrates and stores images for
