3.3.1.1. CONTROL KNOBS AND PRESS KEYS
a) Selecting the digit to be used
This key works in a sequential way and it is associated with 3 LEDs located
above this press key. This allows the operator to select the output in a fine or
course regulation, by changing the digit to be adjusted.
The following resolutions can be obtained:
•
1
digit.
•
10
digits.
•
100
digits.
When pressing this key for more than 2 seconds, it will block the rotating pulse generator,
not allowing any modifications to the level selected.
b) Rotating control knob
This is a rotating pulse generator and has step by step sensation. The values
can be increased or decreased by turning this control knob clockwise or anti-
clockwise by one digit per step, according to the selected digit weight as
described previously.
