then press the button.
The measurement button must be pressed
while a screen that allows measurement
(e.g. Calibration, Target, or Sample screen)
is shown.
Make sure that the specimen is securely
placed in the instrument to prevent leakage
of light.
User calibration data is written to the
instrument using the optional software.
Verify that the calibration plate is correct for
the input calibration data before performing
white calibration or user calibration.
Read page 32 "Zero Calibration" and
perform zero calibration properly.
Read page 18 "Cleaning Parts" and clean
the parts before performing calibration
again.
Do not allow the instrument and specimen
to move during measurement. Use
averaging measurement as needed.
Take care to ensure the specimen is in
contact with measuring port to prevent
displacement or tilting from occurring.

terminal to the computer's USB port with
the USB cable supplied with the instrument.
