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 oper-
ated 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 is used 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
Additional status

Touch area for

Touch areas for menu
access
Quick menu
Touch areas may be enabled or disabled:
Black text = Enabled
Grey text = Touch area temporarily dis-
abled
This applies to all touch areas. Some can additionally show a small padlock sign, indicating that the fea-
ture is permanently locked, usually due to a specific setting.
•
Actual / set values area (left hand side)
In normal operation the DC output values (large numbers) and set values (small numbers) for voltage, current and power are
displayed. The resistance set value of the simulated, variable internal resistance and its actual value are only visible while
resistance mode is activated.
When the DC output is switched on the actual regulation mode is displayed as
CV, CC, CP
or
CR
,
next to the corresponding
actual values, as shown exemplary in the figure above with
CC
.
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 rotation.
