1.9.5.2 Rotary knob
As long as the device is in manual operation the rotary knob is used to adjust set values as well as param-
eters in the setup menu (MENU) or the sequence generator. For a detailed description of the individual
functions see section „3.4 Manual operation“ on page 28.
1.9.5.3 Button function of the rotary knob
The rotary knob also has a pushbutton function, which is used in all menus and in the main screen to move the
cursor of the selected value clockwise (left to right), as shown below:
1.9.5.4 Resolution of the displayed values
In the display, set values can be adjusted in certain increments. The number of decimal places depends on the
device model. The values have 3 to 5 digits. Actual and set values always have the same number of digits.
Adjustment resolution and number of digits of set values in the display:
Voltage,
OVP, U-min, U-max
Current,
OCP, I-min, I-max
Power,
OPP, P-max
