The control panel (HMI)

The HMI (Human Machine Interface) consists of a display with touchscreen, two rotary knobs, a button 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 and set values and the right hand side to display
status information:
Actual voltage display
Voltage set value input
Actual current display
Current set value input
Actual power display
Power set value input
Actual resistance value
Resistance set value input
Touch areas may be enabled or disabled:
This applies to all touch areas on the main screen and all menu pages..
• Actual / set values area (left hand side)
In normal operation the DC input 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 input 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.
