OPERATION
The section explains instrument positioning techniques, Basic Measurement, Quick Compare, and running jobs
from Job Templates.
Instrument Positioning
In order for the instrument to obtain accurate and repeatable measurements, the bottom of the measurement
port must be flat with the sample surface to be measured. Any movement of the instrument can cause the
measurement angles to vary, greatly affecting measurements on metallic and pearlescent paint finishes. The
contact sensors ensure the integrity of the measurement data.
Below is an example of how to position the instrument correctly to perform measurements. Refer to the Basic
Measurement, Quick Compare Mode, and Using Job Templates sections that follow for information on starting a
measurement sequence.
IMPORTANT:
•
To avoid discomfort, do not look directly into the measurement optics when the instrument is on and
measuring.
•
Do not move instrument while taking a sample measurement. If motion is detected by the contact
sensors, an error message will be displayed and the measurement aborted.
•
Measurement performance may decline under certain condensing conditions.
•
It is recommended to keep the sample around 23°C (73°F) as temperature could have influence on the
color measurement.
•
Do not move the instrument on the sample surface with pressure. This may cause scratches to the
sample surface.
1.
Locate the measurement port (1) in the bottom of the instrument over the first measurement area while
viewing the screen (2).
2.
Gently rock the instrument until all three positioning indicators (3) in the screen turn green. This indicates
that all three contact sensors (4) are activated.
3.
Hold the instrument steady and press the Measure button or tap the screen to initiate a measurement in
case the instrument is configured in Manual Mode. If the instrument is configured in Automatic Mode, the
measurement will be triggered as soon as (with a one-second delay) the instrument is correctly positioned
on the sample and all pins are in contact (green indicators on UI). You can also initiate a measurement by
tapping the screen in Automatic Mode if desired
.
Continue to hold the instrument steady until the progress
bar in the screen reaches 100%.
NOTE
: If an error occurs after the measurement, tap
OK
on the screen and try measuring again.
4.
Continue with the remaining area measurements as required.
5.
Refer to the Basic Measurement, Quick Compare Mode, and Using Job Templates sections that follow.
