 The contact surfaces and contact edges of the measuring tool must be
clean. Protect the measuring tool against impact and shock. Debris
particles or deformations can lead to faulty measurements.
Switching On and Off
Press the "ON/OFF" switch 12 to switch the measuring tool on or off.
If the "H" indicator lights up, a value from the last measurement is still saved.
This value can be deleted by briefly pressing the "ON/OFF" button 12.
After approx. 30 minutes without button actuation or angle change, the
measuring tool switches off automatically to preserve battery life.
Aligning with the Spirit Levels
The measuring tool can be aligned horizontally with spirit level 8 and vertical-
ly with spirit level 9.
Rotating the Display
To make the displayed value easier to read, press button 13 to rotate the
display.
Angle Measurement Operating Mode
The measuring tool is in the "Angle Measurement" operating mode every time
it is switched on.
Measuring Angles (see figures C–D)
Place the fold-out leg 1 and the base leg 4 flat on the surfaces adjacent to the
angle. The displayed measuring value c corresponds with the interior angle w
between the base leg and the fold-out leg.
This measured value is shown on the display 7 until you change the angle be-
tween fold-out leg 1 and base leg 4.
Transferring Angles (see figure E)
Measure the angle to be transferred by applying the base leg and the fold-out
leg to the reference angle.
The position of the legs can be locked mechanically by tightening the locking
wheel 3. The displayed value is not saved.
Place the measuring tool in the desired position against the workpiece. Use
the legs as a straight edge to transfer the angle.
Save measured values
Briefly press the "HOLD" memory button 11 to save the current measuring
value. The a indicator will flash on the display as confirmation. The currently
displayed value is frozen and will not change even when the leg is moved. If
you press the "HOLD" memory button again, the a indicator will be shown
permanently on the display. The displayed value will change depending on
the leg movement. The previously frozen value is now saved in the back-
ground. If the "HOLD" memory button 11 is pressed again, the previously
saved value is displayed and the a indicator flashes.
To delete the held value, briefly press button 12.
To be able to save a new value, a previously saved value has to be deleted.
Saved values cannot be overwritten.
The held value is saved even when the measuring tool is switched off (manu-
ally or automatically). However, it is deleted when changing batteries or
when the batteries are empty.
Measuring with Leg Extension (see figures F–H)
The leg extension 17 enables angle measurement when the contact surface
is shorter than the fold-out leg 1.
Place the base leg 4 and the leg extension flat on or against the edges to be
measured.
The reading of the angle w between base leg and fold-out leg is indicated in
the display. The required angle v between base leg and leg extension is cal-
culated as follows:
v = 180° – w
