5.7 Short instructions
This section summarizes the main programming points covered earlier in this chapter.
Use it as a check list once you are familiar with the detailed programming, editing and
running instructions. Refer also to the separate schematic operating guide included
with the power supply. We recommend you keep this schematic guide close by the
instrument.
1. Turn mains power ON. The display should have the program number flashing.
2. Press SET ENTER for the actual program number, or use
/
to select the program
number desired. Press SET ENTER.
3. The display now asks if you wish to perform a step or gradient program. Select with
SET ENTER, or ⁄ with
/
followed by SET ENTER.
4. The display will blink for phase 1. Press SET ENTER to confirm.
5. For each of the parameters Voltage, Current and Power, press
/
until the value
desired is reached. If gradient mode has been selected, the voltage endpoint for the
phase should be chosen. Confirm by pressing SET ENTER after each parameter, and
the display will automatically move to the next parameter.
6. Choose between manual break or automatic break. For automatic break, choose
breakpoint unit in either time (h), volthours (Vh) or milli-amperehours (mAh). Select
the correct unit or, for manual break, choose “OFF” with
/
. Confirm with
SET ENTER.
7. If hours, volthours or milliamperehours were chosen, set the value to be used for the
breakpoint with
/
and SET ENTER.
8. If you only want one phase, press SET ENTER for YES to confirm that this is the last
phase. If more phases are required, select NO with ‘/’ and confirm with
SET ENTER. To add more phases, repeat steps 5–8, until the desired number of
phases have been programmed. Up to 9 phases can be programmed.
9. After all phases have been programmed, you will be asked if you wish for alarms to
sound after the different phases. Press SET ENTER for NO or change to YES and then
press SET ENTER.
10. When programming is completed, connect your electrophoresis unit to the outputs,
and press RUN.
