Calibration
Calibration
Sending the <@CAL> command from ESP’s Terminal initiates auto-calibration without
entering the auto-calibration menu. The calibrated parameters are determined by the
settings of the Calibration Options command.
Lens Calibration
Important:
The
<@OPTIC>
command should only be used when changing the lens module.
Sending the <@OPTIC> command puts the imager into a setup mode for the purpose of
improving the accuracy of the focal distance parameter (<K525>). The imager comes with
a default focal curve based on unit averages. When this isn’t close enough to obtain all
distances, the <@OPTIC> command can be used to start a 2-point test to normalize the
focal distance and improve accuracy. This should generally be done with lenses that were
not originally shipped with the imager.
The table below shows the setting and test requirements to improve distance parameter
accuracy.
