Hold-Function The current actual process current and process voltage values are saved each
time a process ends.
The hold-function relates to the last main current I
main
to be reached.
If other parameters are selected, the set values will be displayed again.
If the I
main
parameter is selected again, the hold values will still be available.
The hold values are cleared when:
- a process starts again
- the process current I
main
is set
- the operating mode is changed
NOTE!
No hold values are output if the main current phase has never been reached.
