Function selection and control
Via the touchscreen one of the functions described above can be called up,
configured and controlled. Selection and configuration are only possible when
the input is switched off.
► How to select a function and adjust parameters
1.
Tap the touch area
not appear it is because the DC input is still switched on or the touch
area is locked due to the device being possibly in remote control.
2.
In the menu overview tap on the touch area
the next page.
Touch area "Function generator" is locked in R mode (adjustable resistance).
4.
Depending on the choice of function there follows a request to which input value the function generator is
going to be applied (
5.
Adjust the parameters as you desire, like offset, amplitude and frequency for a sine wave, for example.
For the AC part of a function and if the difference between start and end value of amplitude
or frequency is too low (min. increment of 0.58%), depending on the time that is defined for
one function run, the function generator will not accept the settings and pop up an error.
6.
Do not forget to adjust the overall limits of voltage, current and power, which you can access with touch
area
.
When entering function generator mode, those global limits are reset to safe values, which
might prevent the function from working at all. For example, if you apply the selected
function to the input current, then the overall current limit should not interfere and should
at least be as high as offset + 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
current), the DC input is switched on and the touch area
Only then can the function be started.
The static values are applied to the DC input immediately after loading the function, because it
switches the DC input on automatically in order to settle the start situation. These static values
represent start and end values for the progress of the function, so that the function does not
need to start from 0. Only exception: when applying any function to the current (I), there is no
adjustable static current value, so the function would always start from 0 A.
