CREATING A JOB AND SAMPLE MEASUREMENT
In order for the device 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 device can cause the measurement
angles to vary, greatly affecting measurements on metallic and pearlescent paint finishes. The pressure sensors
ensure the integrity of the measurement data. It is recommended to complete each job before the next job is
measured to avoid storing incomplete jobs on the device. The measurement sequence is displayed at the
bottom of the screen to help you track your progress for a job.
Measurement Tips:
Measurements performed on a surface with a curve can cause measurement errors especially at the near
specular angles (±15° and 25°). Measurements should be made on the flattest part of a sample whenever
possible.
Hold the device firmly during a measurement.
New Job
The New Job mode is used to create and measure jobs on the device. The device stores measurements as jobs
(multiple measurements per job).
Tap New Job on the main screen. The device automatically goes into targeting mode.
1. Locate the measurement port in the bottom of the device over the measurement area while viewing the
screen.
2. Gently rock the device until all three positioning indicators in the screen turn green. This indicates that all
three pressure sensors are activated.
3. If the device is configured for automatic measurement, the measurement will be triggered as soon as (with
a one-second delay) the device is correctly positioned on the check zone and all pins are in contact (green
indicators on screen). You can also initiate a measurement by tapping the screen in Automatic Mode if
desired. If Manual measurement mode is selected, start the measurement by tapping the screen or by
pressing the Measure and On/Off button.
4. Hold the device steady throughout the entire measurement.
5. After first measurement is finished, lift the device, move it to the next measurement spot and continue with
the remaining area measurements to complete the job.
6. NOTE: You cannot start another measurement until the device has been lifted and repositioned.
7. After the last measurement is completed, the quality of the measurement is indicated with a 5 point system.
Five points indicates excellent measurement without variation between the readings, 3-4 points indicates a
good measurement, and 1-2 points indicates an acceptable measurement. If less than 3 stars, please
repeat measurement.
You can remeasure the job if desired by tapping the
icon and then tapping
Yes
to start the
measurement sequence over.
