1.9.6.2 Rotary knobs
As long as the device is in manual operation, the two rotary knobs are used to adjust set values, as well as
setting the parameters in the settings menu. For a detailed description of the individual functions see section „3.4
Manual operation“ on page 42 . Both rotary knobs have an additional pushbutton function to select the decimal
position of the value to be set. In this way the set current value of a device with, for example, nominal 120 A can
be adjusted in increments of 10 A or 0.1 A (also see 1.9.6.4)
1.9.6.3 Button function of the rotary knobs
The rotary knobs also have a pushbutton function which is used in all menu options for value adjustment to move
the cursor by rotation as shown:
1.9.6.4 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 4 or 5 digits, while actual and set values related to the same physical unit always
have the same number of digits.

In manual operation every set value can be set in the increments given above. In this case
the actual output values set by the device will lie within percentage tolerances as shown in the
technical data sheets. These will influence the actual values.
