Measurement
• Make sure no dust or dirt enters the openings of the instrument.
• When the instrument is used over a prolonged period, the measured values may deviate due to changes in the
environment or other factors. In order to maintain good measurement accuracy, it is recommended that white
calibration and gloss calibration be performed regularly.
Calibration Plate (White Calibration and Gloss Calibration)
• The calibration data for the calibration plate was measured at 23°C. To achieve the highest accuracy when
measuring absolute values, calibration and measurement should be performed at 23°C.
• Do not allow the calibration plate to become scratched or dirty.
• Do not move the calibration plate when it is installed in the sample holder. Doing so may scratch the calibration
plate.
• When the calibration plate is not in use, be sure to close the cover so that the plate is not exposed to light.
Target Mask
• Do not touch the target mask inner surface (black coated surface) with a hand, or allow it to become dirty or
scratched.
• When the target mask is not in use, be sure to place it inside the accessory case (CM-A286) for storage so that it
is not exposed to external light.
Power Source
• Make sure that the power is turned OFF when the instrument is not in use.
• Always use the AC adapter supplied as a standard accessory (AC-A312F) and connect it to a 100 V (50/60 Hz)
AC outlet.
• Use an AC power supply of the rated voltage (within ±10%).
• Make sure the AC adapter output plug is not short-circuited. Failure to do so may cause a fire or electric shock.
• Do not connect the AC adapter to an overloaded electrical circuit. In addition, do not wrap or cover the AC
adapter with cloth or other material while in use. Doing so may cause an electric shock or fire.
• When removing the AC adapter from the instrument, first remove the power cord from the outlet, and then
remove the output plug.
Transmittance Specimen Chamber
• Do not spill specimens or other fluids onto the instrument. If a fluid contacts the instrument, immediately wipe
the fluid off with a soft, dry cloth.
