Manual programming
Manual programming permits to set voltage, current, power and time limits for a simple routine
electrophoresis run. Parameters can be changed temporarily without interrupting the run.
This menu is automatically shown in the EV0220 after start-up.
Verify if the instrument is switched off.
Connect the electrophoresis tank to the instrument.
Switch the instrument on.
