1.9.5 The control panel (HMI)
The HMI (

a USB-A port.
1.9.5.1 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 screen is separated into four areas of equal size, of which three are used to show actual
and set values and one 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
Touch areas MENU and LOCK
Status area
Touch areas may be enabled or disabled:
Black text or symbol = Enabled
Grey text or symbol = Disabled
•
Actual / set values area (blue, red, green, orange)
In normal operation the DC output values (large numbers) and set values (small numbers) for voltage, current and
power are displayed.
When the DC output is switched on, the actual regulation mode,
CV, CC
or
CP
is displayed in the corresponding
area, like depicted in the figure above with “CC” in the red area for current.
The set values can be adjusted with the rotary knobs below the touch screen or can be entered directly via the
touchscreen. When adjusting with the knobs, pushing the knob will select the digit to adjust. Logically, the values
are increased by 1 in clockwise turning and decreased by 1 in anti-clockwise turning, until reaching any limit (see
„3.4.4. Adjustment limits (Limits)“
).
