1. Connect the main power cord: Connect the main power cord to the power cord receptacle
on the rear panel and to a suitable grounded AC power outlet.
2. Connect the HV power leads: Connect the apparatus to the power supply by plugging the
lead connectors into one pair of the recessed output jacks. The power leads are
non-reversible as per to the color coordinated to the output jacks.
3. Turn on the main power switch: Turn on the main power switch on the rear panel. The
front panel and the main power LED indicator should be illuminated.
4. Select constant mode: Press the CONST button to toggle between constant voltage and
constant current mode. The selection is indicated by the green LED.
5. Adjust limit: Press up and down buttons to set the constant variable to the desired value.
6. Check other run variable: Press the MODE button to check and verify the set value of the
other (non-constant) run variable. This variable is set by default to the maximum output of
the power supply. This is the normal condition or setting for simple electrophoretic
separations. Optional: If there is another upper limit desired for this non-constant variable,
use the up and down buttons to set it to the desired value.
7. Set the timer (Optional): Press the MODE button to move the green indicator LED light to
under clock symbol.
Continuous run: Leave the timer at “0” to start a continuous run. The power supply will
continue to operate indefinitely, until stopped manually. The timer will start counting up,
indicating the length of the run in minutes. After reaching the maximum time of 999 minutes
the timer will automatically reset and recount again from 0. Therefore for over night
operation the resulting operation time is the addition of the current timer value with the
previous maximum timer 1440 minutes.
Timed run: Press the up and down buttons to set the timer to the desired value (minutes).
The timer counts down during the run, indicating the time remaining. At the end of the timed
run, a ~3 second beep sounds and the display changes to “OFF”. To reset the power supply
press any button except the RUN button.
