Setting breakpoint
Choose between automatic or manual break. For automatic break, choose breakpoint
unit in either hours (h), volthours (Vh) or milliamperehours (mAh). Select the correct unit
or, for manual break, choose "OFF" with /  . Confirm with SET ENTER.
Note that the breakpoint unit is valid for all phases within the program and you will only
get this question when programming the first phase, see "Other phases" bypass in Fig 3.
If h, Vh or mAh is chosen, the display will flash for the break value for the actual phase.
Set the value with /  and confirm with SET ENTER. Programmable values for time are
0:01–500 h, volthours, 1–500 000 Vh, milliamperehours, 1–25 000 mAh.
If OFF is chosen, you have to break the electrophoresis manually by pressing STOP and
only one phase can be entered. The program will go back to the start position and the
program number will flash.
Last Phase?
After programming the breakpoint you are asked if this is the last phase or not. Select
YES or NO with /  and confirm with SET ENTER.
If YES is selected, no more phases will be added and the alarm question will be shown,
see below.
If NO is selected, the next phase number for the program will be shown on the display
together with zero values for all parameters. Program the next phase according to
"Setting voltage, current and power" above and Fig 3 point 4. Up to nine phases can be
programmed.
Choosing alarm
The alarm can be set separately for each phase. The following question is shown:
Alarm Phase 1? Select YES or NO with /  and confirm with .
If YES is selected in a 4 phase program this will be indicated by changing from - - - -
to 1 - - - after "Phase:" on the lower row in the display. Then you will be asked about an
alarm for the next phase. After answering YES or NO for the last phase, the start position
in the SET mode will be shown. If alarm is selected for a phase a small "A" appears on the
right of the phase number, i.e. 2 2A.
Back to start position
The program is now back to the start position in the SET mode with the program number
flashing. It is possible to go back to this position at any stage during programming in
SET mode by pressing EXIT or STOP. Note that the program is automatically saved with
all choices that have been confirmed by SET ENTER when EXIT or STOP is pressed. If a
phase containing invalid values (zeros) is left, this phase will be deleted.
Disabling the start current check
See Section 5.5 if you want to use this feature.
