View programmed values
Press SET/ENTER to view the programmed values during a run. If the keyboard is idle for
4 seconds or you press RUN the display goes back to the actual values.
Change parameters during a run
When the method is running, changes can be introduced in the program by pressing
SET/ENTER and using / . Confirm by pressing SET/ENTER or RUN
Stop the run
When the programmed time has elapsed, the program will enter the End mode and the
alarm will sound. You can stop the alarm by pressing any key. It is also possible to break
the run manually by pressing STOP. In both cases, the values for voltage and current will
go to zero, as indicated by the light emitting diode switching off.
View end parameter values
Display the end parameter values by pressing VIEW.
Post electrophoresis
Disconnect the leads and proceed with post-electrophoretic techniques. Since the quality
of your separation will deteriorate due to diffusion, you should remove the gel and begin
staining or blotting immediately.

Short instructions

This section summarises the main points covered earlier in this chapter. Use it as a
check list once you are familiar with the detailed programming and running instructions.
Refer also to the separate short instruction EPS 301 included with the power supply. We
recommend you keep this separate short instruction close by the instrument.
1. Turn mains power ON. The program enters the End mode. If the programmed values
from the last run are to be used again, go to point 4 below. To change the program,
press SET/ENTER to enter the program mode. The voltage symbol V is lit and the
value for voltage flashes. The programmed value from the last run is displayed.
Use / to set to the desired voltage. Press SET/ENTER to confirm. If the voltage
value is correct from the beginning just press SET/ENTER to confirm.
2. The display shows the last programmed value for current flashing. Press
the desired value is reached. Confirm by pressing SET/ENTER.
3. The value for time is now flashing. Use
set the time to zero. Indicated by - - - -. Confirm by pressing SET/ENTER.
4. When programming is completed, connect your electrophoresis unit to the output(s),
and press RUN.
5. Press VIEW to display actual voltage, current and elapsed time. Press VIEW for
more than three seconds to start automatic switching of actual values.
6. Press SET/ENTER during the run to check the programmed parameters and change
the values by pressing
7. The program stops automatically on completion or on STOP being pressed.
