an USB 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 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
Status area
Touch area for
rotary knob assignment

and SETTINGS
Quick menu
Touch areas may be enabled or disabled:
Black text = Enabled
Grey text = Touch area temporarily
disabled
This applies to all touch areas. Some can additionally show a small padlock sign, indicating that
the feature 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. Resistance set value of the simulated, variable internal resistance is only displayed with
active resistance mode.
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 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 rotation.
