“Normal Measuring Mode”

After switching on, the measuring tool is always in normal

measuring mode.

Measuring Angles (see figures C–E)

Place the fold-out leg 1 and the base leg 4 flat on the

surfaces adjacent to the angle. The displayed measuring

value a corresponds with the interior angle w between the

base leg and the fold-out leg.

This measuring value is indicated on both displays 6 until

the angle between the fold-out leg 1 and the base leg 4 is

changed.

Transferring Angles (see figure C)

Measure the angle to be transferred by appyling the base

leg and the fold-out leg to the reference angle.

Place the measuring tool in the desired position against the

workpiece. Use the legs as a straight edge to transfer the

angle.

Take care that the position of the fold-out leg and the base

leg is not changed during transferring.

Marking Angles (see figure D)

Open the fold-out leg and the base leg until the required

angle is indicated in the display a.

Place the measuring tool in the desired position against the

workpiece. Use the legs as a straight edge to transfer the

angle.

Storing a Measured Value (“Recall / Hold”)

To store (“Hold”) the current measured value, press the

“Recall / Hold” button 9 for at least 1 s. The reading a and

the “HOLD” indicator flash twice on the display; after-

wards, “HOLD” is indicated continuously.

To recall the held value, briefly press the “Recall / Hold”

button 9 (less than 1 s). The held value flashes in the

display.

To delete the held value, close the fold-out leg 1 and the

base leg 4 so that the angle 0,0° is indicated. Then press

the “Recall / Hold” button 9 for more than 1 s. The held

value is deleted and the “HOLD” indication on the display

is annulled.

The held value is saved even when the measuring tool is

switched off (manually 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 3

makes it possible to measure angles

when the contact surface is shorter than the fold-out leg 1.

Mount the leg extension 3 (see “Mounting the Leg Exten-

sion”, page 16). Place the base leg 4 and the leg extension

flat on the surfaces adjacent to the angle.

The reading of the angle w between base leg and fold-out

leg is indicated in the display. The required angle v be-

tween base leg and leg extension is calculated as follows:

v =180°–w
