8.4 Cleaning the Measuring Window
When the measuring window gets fingerprints or dust on it, the reliability of the measured value
will be lowered substantially. Check the dirt on the measuring window before use, and then
clean it if it is dirty.
1. Blow off the dust on the measuring window with a blower.
2. Wrap the lens cleaning paper around a thin
stick such as a chopstick (or cotton swab)
and wipe the glass of the measuring window
with a material moistened with alcohol.
Use a thin stick which will not damage the glass.
(Never use hard objects such as a metal
product.)
Wipe the measuring window lightly from center
to outside along an arc.
Pay attention not to put alcohol onto the sensor
window and cover, etc. except the measuring
window.
3. Check if the window is cleaned using a
penlight. If not, clean it again with a new
cleaning paper.
Apply light with a penlight and change the view
angle to check the dirt clearly.
Wrap a cleaning paper around the tip.

Be sure not to wipe the sensor window except
the central measuring window with alcohol.
Wipe the dirt of the sensor window with a dry
cleaning paper.
