7. Measurement techniques
Inordertoobtainaccurateandrepeatable
measurements, the bottom of the instrument must
bealignedatonthesurfacetobemeasured.Do
not move the instrument while measuring. This can
cause the measurement values to vary.
Use the alignment marks on both sides of the
instrument to center the measurement aperture
over the desired area.
To perform a measurement, all three pins on the
bottom must be completely pressed down while the
operate button is pressed.
Alternatively, the instrument can be set-up to
perform a measurement by just pressing the three
pins (auto measure).
A measurement requires four readings to be taken
around the repair area to complete one stored
measurement.
The display will guide you through the readings.
7.1 Light protection ring
The measurement aperture of the instrument is
surrounded by a light protection ring made out
ofrubber.Itactsasaprotectionagainstambient
light. Keep the ring allways clean and change it
when being damaged (see section Cleaning and
Maintenance).Incaseitleavesmarksonthe
panel, clean the marks with water and soap.
