Pausing
You can interrupt the electrophoresis for sample loading and/or changing the program
by pressing PAUSE CONTINUE. Voltage will no longer be supplied, the “HV on” LED goes
off, and you may safely load your samples. The display shows the status of the run
when PAUSE CONTINUE was pressed.
Switch between time, integrated voltage and integrated current for the phase running
when PAUSE CONTINUE was pressed with
/
.
When sample loading is complete, press either PAUSE CONTINUE again or RUN to
continue the run from where it was interrupted.
Editing a running program when in PAUSE
When in the PAUSE mode you can also press SET ENTER to make changes in the
program. This mode is called the P-SET mode. When the P-SET mode is entered you can
make changes as described in the editing section (5.3, Changing a parameter value). It
is not possible to insert or delete a phase for a running program. The P-SET mode is the
same as the SET mode apart from restrictions in setting the breakpoint. Naturally, it is
not possible to enter a time, integrated voltage or current that is already passed.
Press EXIT or PAUSE CONTINUE to go back from P-SET to PAUSE. Press RUN or PAUSE
CONTINUE to proceed with the electrophoresis.
