Method programming permits to store up to 9 different methods, each
with 9 steps, of frequently used parameters in the non-volatile memory
for future recall. Each step is able to recall a next one, provi ding a flex-
ible multiple step function for special techniques. The method mode also
permits to program a linear voltage gradient for any step provided the
limiting current or power is not attained. 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. If the timer is still running after switching
on, the power supply will automatically proceed with the experi-
ment for the remaining time. Press STOP (within 10 seconds) if you
want to go in stand-by during the run. The parameters can then be
changed eventually. Press RUN to proceed with the experiment or
press SET, during 2 seconds, to go in stand-by again.
4. Select the METHOD mode and press SET.
5. Select the desired method and press SET.
6. Select the desired step and press SET.
7. Decide whether or not a voltage gradient has to be performed and
press SET.
8. Enter the desired voltage limit and press SET (= the voltage end
point in case of a gradient step).
9. Enter the desired current limit and press SET (this limit is automati-
cally set to maximum and cannot be changed in case of a gradient
step).
10. Enter the desired power limit and press SET (this limit is automati-
cally set to maximum and cannot be changed in case of a gradient
step).
11. Enter the desired time-units (h of kVh) and press SET.
12. Enter the desired time and press SET.
13. Decide if the experiment should automati cally proceed with a next
step (resuming from point 6) or stop after this step. Enter the
desired procedure and press SET.
14. Press RUN to start the experiment.
•
At any time, you can return in the stand-by mode by holding SET pressed during 2
seconds.
•
At any time, you can avoid programming unnecessary parameters. To do so, simply
press RUN instead of SET after entering the last relevant value and the instrument
will immediately start the experiment keeping the other parameters to their previ-
ous values.
•
To ensure that the desired parameter is kept constant, we suggest to pre-set all
other parameters to maximum.
•
A blinking unit of the controlling parameter appears when the regulation is com-
plete.
•
The timer will always count down.
