FUNCTIONS/IDENTIFICATION
ON/OFF BUTTON
Simply press once to enter the measurement mode and
again to turn it off.
HOLD BUTTON
Press the button and hold the protractor in position for 6
seconds to freeze the reading until the button is pressed
again to cancel.
ZERO BUTTON
If the icon ABS is displaying you are in horizontal measurement mode.
If you then press the ZERO button you will be in relative measurement mode
and the ABS icon will disappear.
CALIBRATION
The digital protractor needs to be calibrated
before you use it, or if you push the on/off
button for longer than 6 seconds.
1. Place the unit on a flat surface, facing
you, with the lettering the right way up.
Align with an edge or a line. Press the
on/off button and the
-1-
will appear.
2. Press the ZERO button and check that
the
-1-
is blinking.
3. Wait 6 seconds until the
-2-
appears.
4. Turn the unit 180 horizontally so that the
unit is facing away from you, keeping the
display the correct way up. Align with the
same edge or line. Press the ZERO button,
the
-2-
will blink, wait 6 seconds until the
actual angle appears, the calibration is
finished.

HORIZONTAL MEASUREMENT
5. In the horizontal measurement mode,
the ABS icon is visible.
6. Put the unit on the surface needed to
be measured. The protractor shows the
angle of the measured surface to the
horizontal plane.
(to get the most accurate reading allow
the unit to settle for 6 seconds).
RELATIVE MEASUREMENT
Setting an alternative reference
point. This allows you to set any
angle as 0.0
°
reference, the point
from which to take
measurements.
For example, you may want to
measure an angle against a
reference point which is already at
25
°
to the horizontal plane.
7. With the protractor set in the
horizontal mode (the ABS icon is
visible). Put the unit on the
surface that is actually 25
°
to
the horizontal plane.
8. Press the ZERO button to
change to relative measurement
mode (the ABS icon is not visible)
and the angle readout is
-00.0-
9. Put the protractor on the surface
that is actually 60
°
off the
horizontal plane and you will see
-35.0-
displayed. This is the
angle relative to the surface
which is actually 25
°
off the
horizontal plane.
