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.
1.
Verify if the instrument is switched off.
2.
Connect the electrophoresis tank to the instrument.
3.
Switch the instrument on.

The value format is 'hh:mm' when entering a
value in hours. The format is a value with 2
decimals when entering kiloVolthours. Set to
zero when required to continue until

•
At any time, you can return to the main menu by holding
pressed.
•
At any time, you can avoid programming unnecessary parameters. To do so, simply press
/
instead of
after entering the last relevant value and the instrument will immediately start the experiment keeping the
other parameters to their previous values.
•
To ensure that the desired parameter is kept constant, we suggest to pre-set all other parameters to its
maximum.
•
A blinking unit of the controlling parameter appears when the regulation is complete.
•
The timer will always count down except when no timer value has been entered.
