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
Press SET ENTER.
3. The display now asks if you wish to perform a step or gradient program. Select

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
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
"OFF" with
break, choose
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.
