Inserting batteries:

Open the battery compartment (16) on the rear of the device and insert 
two new batteries (AA/LR6) as per the installation symbols. Correct polarity 
must be observed.

• As soon as the battery symbol (5) lights up, replace the batteries.

Switching on and measuring:

The ArcoMaster can measure angles continuously from 0° to 220°.

• Press button (1) to switch the device on.

• All display symbols appear for a couple of seconds.

•  Place the measuring arm at the required position; the value of  

the measured angle (opening angle between the base arm and  
the folding measuring arm) appears on the display (7).

• The measured value can be read from both displays.

NOTE:

 The barely audible noise emitted by the pivot joint is due to  

a precise sensor and is part of the design.

Flip display can be rotated 180°

•  If angles are to be measured overhead, press button (1) brie

fl

y  

and repeatedly to rotate the display by 180°.

Holding an angle (HOLD)

•  Button (3) can be used to hold the measurement results; once  

they have been transmitted, pressing button (3) again will reset them.

Changing the reference angle:

•  Angular differences can be transmitted using button (4): Set the required 

angle and press button (4). The display then changes to “0.0” and (S)  
also appears. The required reference angle is now set and can be  
transmitted to other objects. This function can also be used to measure  
an angular difference. 

IMPORTANT:

 Once all angles have been transmitted, the new reference  

angle must be cleared; to do this, press the REF button repeatedly.  
Switching the device off/on will also delete the REF value.
