How to select a function and adjust parameters
1.
While the DC terminal is switched off tap touch area
on the main screen. Note: this icon is locked
as long as resistance mode (R mode) is enabled.
2.
In the menu select the desired function by tapping on the list on the left-hand side. Depending on the choice
of function there follows a request to which value the function generator is going to be applied,
Voltage or
Current .
3.
Adjust the parameters as you desire.
4.
Adjust the overall limits of voltage, current and power, then continue with
.
5.
As last part of the configuration, global set values have to be defined which are considered as static values
and come into effect before and after the function run. Correct setup here is important,
especially when
running the function on a master device of a master-slave system.
• When intending to run a function exclusively in sink or in source mode, it’s recommended
to set the set values (I, P) of the opposite mode to 0.
•
The global limits of U, I and P become instantly active when coming to the main screen
of the function generator, because the DC terminal is then switched on automatically to
settle the start situation. This can be helpful when wanting a function shall not start at 0 V
or 0 A. In case the situation requires otherwise, the static values could also be set to 0.
6.
Exit the configuration and enter the main function generator screen with
.
Setting the various functions and their parameters is described below. After the function generator screen has
been reached, the function is ready to run. Before and while the function is running, some global and also some
function related values can be adjusted anytime.

How to start and stop a function
1.
The function can be started either by tapping or
if the DC terminal is currently switched off by pushing
the “
On/Off
” button on the front.
2.
The function can either be stopped by tapping
or operating the “On/Off” button. However, there is a
difference:
a) The button only stops the function while the
DC terminal remains ON with the static values in
effect.
b) The “On/Off“ button stops the function and switches
the DC terminal off.
Any device alarm (power fail, overtemperature etc.), protection (OPP, OCP) or event with Action
= Alarm stops the function progress automatically, switches off the DC terminal and reports the
alarm.
