Allowed tolerance for the power
The settling process of the power supply is determined by
the load. After a set value has changed, a certain time elapses
until the desired value is put to the power output. For instance,
it can last some seconds for the voltage to go down from
100% to 0V at no-load operation, because the output
capacitors need a certain time to discharge.
Supervision of a step response
The adjusted set value is compared with the measured actual
value. If there is a difference between them and this difference
is greater than the tolerance, the supervision will initiate an
error after the settling time
Tsr
. See figure below.

You can reset all modifications of the setup to the default
setup (the state the unit had when it was delivered).
After selecting the corresponding menu entry you will be
prompted again to submit the choice to reset your current,
personal configuration.
Attention:
Even if the device configuration has been locked
by a PIN it will be unlocked and overwritten!
