1.10.6.3 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 pages SETTINGS and MENU. For a detailed description of the individual
functions see section „3.3 Manual operation“ on page 43. Both rotary knobs have an additional pushbut-
ton function whereby the decimal position of the value to be set is moved. In this way, for example, the set current
value for a device with nominal 120 A can be adjusted in increments of 10 A or 0.1 A or different. (see also „1.10.6.2
Pushbuttons“ on page 29)
1.10.6.4 Resolution of the displayed values
In the display, set values can be adjusted in variable increments. The number of decimal places depends on the
device model. The values have 4 or 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 of stand-alone devices are as shown in the
table below. The display format of values in master-slave operation, then displayed by the master unit only, will differ.

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 inuence the actual values.
