measurements, the bottom of the instrument must
bealignedatonthesurfacetobemeasured.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.
