Remarks :

The three Timed Presets share the same Icon of the single V & I Presets. But they

have  run  time  settings  and  a  cycle  setting.  The  power  supply  can  thus  be

programmed to operate from one Timed Preset which runs for a set time period

and moves to the next lot of Timed Presets. 
When the power supply is in cycle operation the cycle icon  

 flashes with the

time preset in operation.

Setting the Timed Presets

1. Push Button (4) to Output “OFF” position, check display to confirm.

2. Press and hold the voltage knob for about 5 seconds to enter into the setting 

mode with flashing “Preset Icon” as shown below.

3. Use voltage knob to adjust voltage for U1, press voltage knob to confirm new 

setting.
