3.11.4 Manual operation
3.11.4.1 Function selection and control
Via the touch screen one of the functions described in 3.11.1 can be selected,
conguredandcontrolled.ThisisonlypermissiblewhiletheDCterminalis
switchedo󰀨.
► How to select a function and adjust parameters
1. WhiletheDCterminalisswitchedo󰀨tapthetoucharea
on the main screen.
2. In the menu tap on the touch area and then on the desired function.
Note: this touch area is locked in R mode (adjustable resistance).
3. Depending on the choice of function there follows a request to which value the function generator is going
to be applied: or .
4. Adjusttheparametersasyoudesire,likeo󰀨set,amplitudeandfrequencyforasinewave,forexample.
5. Adjust the overall limits of voltage, current and power, which you can access with touch area .
When entering function generator mode those limits are reset to safe values, which can prevent
the function from working at all. For example, if you apply the selected function to the output
current (source mode), then the overall current limit shouldn’t interfere and should at least be
as high as oset + amplitude.
Setting the various functions is described below. After setting it up, the function can be loaded.
► How to load a function
1. After setting the values for the required signal generation, tap on the
touch area .
The device will then load the data into the internal controller and changes the
display. Shortly afterwards the static values are set (power and voltage or cur-
rent), the DC terminal is switched on and the touch area enabled.
Only then can the function be started.
The static values are applied to the DC terminal immediately after loading the function and
in order to set the start situation. They represent start and end values for the progress of the
function, so that it doesn’t need to start from 0. Only exception: when applying a function to the
current (I), there is no adjustable static current value, so the function would always start from 0 A.
► How to start and stop a function
1. The function can be started either by tapping orpushingthe“On/O󰀨”button,iftheDCterminal
iscurrentlyswitchedo󰀨.Thefunctionthenstartsimmediately.IncaseSTARTisusedwhiletheDCterminal
isstillswitchedo󰀨,itwillbeswitchedonautomatically.
2. The function can be stopped either by tapping oroperatingthe“On/O󰀨”button.However,there
isadi󰀨erence:
a) The button stops only the function, the DC terminal remains ON with the static values.
b)The“On/O󰀨“buttonstopsthefunctionandswitchestheDCterminalo󰀨.
Any device alarm (overvoltage, overtemperature etc.), protection (OPP, OCP) or event with
action = Alarm stops the function progress automatically, switches o the DC terminal and
reports the alarm.
