Calibration check
It is necessary for the user to visually inspect the calibration tile for
smears or defects before calibration.
The instrument will also automatically check the condition of the standard
tile. If the reading is outside calibration tolerances the following warning
messages will be seen:
The white tile must be checked for permanent marks and deep scratches.
If these are seen on the tile the CLEAR key should be pressed – the
calibration value will not be stored. The tile must then be carefully cleaned
and inspected. The calibration procedure must then be repeated. See
page 12 for cleaning procedure.
*Note: If there are permanent marks or scratches the tile must be returned for
recalibration by Rhopoint Instrumentation.
Checking the calibration value
Place the instrument on the white calibration tile and take a reading by
pressing the READ/SELECT key.
Compare the measured value with the assigned value of the tile. If the
value matches the value printed on the tile case the instrument is within
calibration and ready for use.
If the readings do not match it will be necessary to check the value for
the tile stored in the instrument memory – see the ‘Set calibration value’
section (page 24).
