Action
Connect the AC adapter.
Wait until measurement is complete, and then
press the button.
Measuring 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.
To perform user calibration or Petri Dish
measurement, you need to input appropriate
calibration data to the instrument by using the
optional software. Check that the calibration
plate is correct for the input calibration data
before performing white calibration (100%
calibration) or user calibration.
Read page 52 "Zero calibration (0% Calibration)"
and perform the calibration properly such as by
using the optional Zero Calibration Box.
Do not allow the instrument and specimen to
move during measurement.
Connect the instrument's USB connecting
terminal to the computer's USB port with the
USB cable supplied with the instrument.
Connect the USB memory to the USB connection
terminal of the instrument properly and securely.
If the problem continues, turn OFF the
instrument once and turn it ON again, and then
connect the USB memory.
Connect the RS-232C connector of the
instrument and the connector of the printer with
the optional connecting cable or the cable
conforming to the requirements shown in the
connection diagram on page 146.
