Setting a film specimen
Water drops formed on a specimen due to condensation or other causes prevent accurate measurement.
Notes
1. Open the specimen fixing plate and secure a specimen
with the plate.
When setting the specimen on the illumination window

side, position it so that it fully covers the illumination
window. When setting the specimen on the receiving
window side, position it so that it fully covers the receiving
window.
Setting a liquid specimen
• As for the container for a liquid specimen, it is recommended to use the CM-A97 to 99 Cell or CM-A130 to 132
Notes
Plastic Cell provided as the optional accessory. To use other containers, use a colorless, transparent container
with surfaces which are parallel with the illumination window and receiving window of the instrument.
• The Cell is fragile and it must be handled with care.
• Do not pour hot liquid in the Cell or Plastic Cell, and do not wash them with hot water.
• When cleaning the Cell or Plastic Cell with an ultrasonic cleaner, do not clean them for a long time to prevent
damage.
• The measurement values obtained with cells having different optical path lengths may not be compatible with
each other.
• Do not spill a specimen or other liquid on the instrument. Doing so may cause malfunction. If any liquid is
spilled on the instrument, wipe it off immediately with a soft, dry cloth.
• Do not measure inflammable liquid.
• Ensure that there are no dust, stains, scratches, or fingerprints on the specimen or on the inner and outer surfaces
of the container of a liquid specimen. Set a specimen by holding a section other than the measurement surface to
avoid fingerprints.
• Bubbles in the container containing a liquid specimen prevent accurate measurement. Be sure to remove bubbles
before measurement. (Sometimes bubbles may be generated when a specimen is left for a while.)
• Water drops formed on a specimen or the container containing a liquid specimen due to condensation or other
causes prevent accurate measurement.
• The measurement accuracy for liquid containing fine particles may be unstable due to the deposition of the
particles.
Memo When measuring a transparent index such as Gardner, etc., use the Transmittance Specimen Holder (10 mm wide)
and a 10 mm-wide cell with an optical path length of 10 mm.
1. Pour a specimen in a transparent container.
2. Open the specimen fixing plate and secure the container
with the plate.
• When setting the specimen on the illumination window
Notes
side, position it so that it fully covers the illumination
window. When setting the specimen on the receiving
window side, position it so that it fully covers the
receiving window.
• When using a cell or plastic cell, use the cell guide to
determine the center of the cell.
