Calibration - Rhopoint Instruments Optimap PSD 3 Manual

8.6.1 Calibration

Before measuring with Optimap3, you must calibrate the instrument. The calibration
procedure will adjust camera focus position and get results of the reference surface (a
top coated glass silver mirror).
To calibrate the Optimap3, you need the calibration plate provided with the instrument
in the box. This plate has two sides:
o Surface reference plate: used for focus surface settings
o Silver reference plate: use for focus screen settings and reference
measurement
To start the calibration, press the calibrate button on the settings screen. The
Optimap3 will guide the user through the calibration steps.
Calibration step 1:
The Optimap3 will first ask to place the instrument onto the surface ref tile. Make
sure that the instrument is sitting properly on the surface and press start (at that
time, the process is now running). The system is performing surface auto-focus
setting.
Calibration step 2:
If the first step is successful, then the Optimap3 will ask to place the instrument onto
the silver ref. plate(mirror), on the reverse of the surface reference. Make sure that
the instrument is sitting properly on the surface and press start. The system is
performing screen auto-focus setting and measurement calibration.
