2  Tuning Mode (Basic Tuning Functions) 

The basic tuning functions are summarized in the “Quick Reference Guide for the Tuning Mode“. 
To become well familiar with the Tuning Set, follow the operating examples below on a musical 
instrument and stick closely to the instructions. 
 

2.1 Strobe display 

Strike the tone a1 on your instrument.

Two fields of green 

light will appear in the strobe display.  

When the played tone is too low or too high, these fields move to the left or right accordingly. 
When the tone comes closer to its target value, the movement becomes slower.  
Once the tone is correct, the fields stop moving.  

You can recognize large frequency deviations, when 
one of the two green dots on the left or right of the 
strobe display is lit. Depending on whether the tone 
being tuned is too high or too low, either the right or the 
left dot will be lit continuously. If neither of these two 
dots shine, the tone played is at the desired pitch of +/- 
4 cent. If a strobe field moves across the display once 
in 20 seconds, the frequency deviation is 0,1 Hertz. 

2.2  Bar graph display 

In the tuning mode, you can switch between the bar graph and the concert pitch display with the 
“E” key. 

Press the “E“ key. When you now strike the tone a1 on your 
instrument, the arrow points to the right, if the tone played 
is too high, and to the left, if it is too low.
