Note
• If the standard plate inside the protective cover is floated
from the measurement area or scratched, the measurement
value will be smaller than it should be. Replace the entire
protective cover before calibration.
• If the standard plate or lens is dirty, the measurement value
will be smaller than it should be. Clean the lens and standard
plate (refer to page 42) before calibration.
• If calibration is performed using an object other than the
standard plate supplied with the protective cover, the
accuracy of the measurement value cannot be guaranteed.
• Calibration stops with an error indication in the following
cases.
• When the protective cover is not correctly attached
• When calibration is performed using an object other than
the standard plate, and the gross value of the object is
too large or too small
• When the gross value is unstable
