OPERATING PROCEDURE: Measurement Method
3.2.2 Checking the measuring window cleanliness at device start-up
It is possible to set the parameter whether or not to check the cleanliness of the measuring window
before measurement.
Window check contents at device start-up differ depending on the “61. WINDOW CHECK” parameter
setting.
An unclean measuring window has considerable influence on the measured results. In addition to
visual inspection, this checking function should be used for measurement with a clean measuring win-
dow.
1)
“MEASURING WINDOW / CHECKING” is displayed and
the measuring window is checked for cleanliness.
Wait until a message appears.
2)
A message appears.
“WINDOW CHECK OK!”
The measuring window is clean.
“CHECK MEASURING WINDOW”
“CHECK MEASURING WINDOW” is printed out as dis-
played on the screen.
Check that the measuring window is clean. If not, clean it.
3)
At the completion of the check, the screen switches to
the measurement screen.
DAY The measuring window is checked at the first startup of the day.
YES The measuring window is checked every startup.
NO The measuring window is not checked.
• When checking the measuring window, be sure that its front is not blocked by objects or exposed to
interference light.
Even if the window is not smudged, it may be determined that it is smudged due to objects or interfer-
ence light.
• At device start-up, do not stand or put objects in front of the measuring window.
If something is present in front of the measuring window within 1 m, the measuring window may not be
properly checked for cleanliness.
