Cautions
● The spectrophotometer is a precise measuring instrument. Please avoid dramatic
changes of external environment when measuring. These changes, including the
flicker of surrounding light and the rapid change of temperature, will affect
measurement accuracy.
● Keep the color meter balanceable; make sure the measuring aperture close to the test
sample, and no shaking or shifting when measuring. Please prevent the colorimeter
from fierce collision or crash.
● The instrument is not waterproof. Do not use it in high humidity environment or in
water.
● Keep the instrument clean. Avoid dust, powder or solid particles entering the
measuring aperture and the instrument.
● Replace the white calibration cavity and put the spectrophotometer into instrument
case when not in use.
● Please take out the battery to prevent the instrument from damage if you don’t use it
for a long time.
● Please keep the instrument in a cool dry place.
● Any unauthorized changes to the instrument are not permitted, or it will affect the
measuring accuracy, even cause irreversible damage.

4.3 Measurement
4.3.1 Measurement Locating
The instrument can visually locate through the cross of measuring aperture. It can
be done by observing the alignment between the cross and the sample, while
moving the measuring aperture to adjust the position.
4.3.2 Standard Measurement
Please enter “Standard Measurement” interface to perform measurements as
shown in Figure 6.
Put the measuring aperture on the standard sample, press “Testing” key. The
colorimeter will display color data of the standard sample.
