The HMI (

Human Machine Interface) consists of a display with touchscreen, two rotary knobs, a pushbutton and 

a USB-A port. 
1.9.6.1  Touchscreen display
The graphic touchscreen display is divided into a number of areas. The complete display is touch sensitive and 

can be operated by finger or stylus to control the equipment.
In normal operation the left hand side is used to show actual values and set values and the right hand side to 

display status information:

Actual voltage display

Voltage set value input

Status area

Actual current display

Current set value input

Touch area for 

rotary knob assignment

Actual power display

Power set value input

Actual internal resistance

Resistance set value input

Touch areas MENU 

and SETTINGS

Touch areas may be enabled or disabled:

  Black text or symbol = Enabled

  Grey text or symbol = Disabled

This applies to all touch areas on the main screen and all menu pages..

•

In normal operation the DC output values (large numbers) and set values (small numbers) for voltage, current and 

power are displayed. Resistance set value of the variable internal resistance is only displayed by active resistance 

mode. 
When the DC output is switched on, the actual regulation mode, 

CV, CC, CP or CR is displayed next to the cor-

responding actual values, as show in the figure above.
The set values can be adjusted with the rotary knobs next to the display screen or can be entered directly via the 

touchscreen. When adjusting with the knobs, pushing the knob will select the digit to be changed. Logically, the 

values are increased by clockwise turning and decreased by anti-clockwise turning.
