Section 2 - Calibration
The software application prompts for an instrument calibration
when required. The frequency at which this occurs depends on
the application. Refer below for procedure.
The calibration reference consists of a ceramic disk for white
calibration measurements, and a trap opening for black
calibration measurements. The instrument shoe fits snuggly in
both positions.
NOTE:
Make sure the calibration reference is clean before use. Refer to
the calibration cleaning procedure in the Appendices.
1.
When a calibration is prompted for by the application,
select the appropriate option to initiate the calibration. The
instrument LED should be flashing amber at this time.
2.
Position the instrument target window over the white
ceramic disk of the calibration reference.
3.
Press the instrument firmly to the shoe, the LED stops
flashing (solid amber). Hold steady until the LED changes
to green, followed by an audible beep.
4.
Release the instrument. The LED will again flash amber.
