(black) of the CH1 output terminal.
4. Set the voltage, current, overvoltage and overcurrent protection:
Refer to chapter "Constant Voltage Output". All the channels in parallel connection should be operating in
constant voltage mode.
5. Turn on the output:
Press the
key of CH1 or CH2 to enter the parallel connection output mode. At this time, the CH1 and CH2
output indicators are green (CV mode) and red (parallel connection or CC mode) respectively. If the CH1 indicator
is red too, please check whether the set current meets the load requirements.

List Mode (Timer) and Delayer
UDP3305S series power supply provides the timer and delayer functions.
When the timer is enabled, the instrument outputs the preset parameter groups (at most 2048 groups): voltage,
current and timing time. Besides, users can define the parameter groups by calling the template that comes with
the system.
When the delayer is enabled, he instrument outputs the preset parameter groups (at most 2048 groups): enable
or disable output and delay time. Besides, users can define the parameter groups by calling the system's automatic
generation function.
The output parameters of the list mode and the delayer can be saved in the internal memory of the system. 10
groups can be stored each, and users can define the file name. Users can also store list mode parameters (list mode
file, with the suffix ".LST") and delayer parameters (delay file, with the suffix ".DLY ") in external memory. The
number of external storage files is not limited by the system, only limited by the size of the external storage space.
Operation steps:
1. Press the power switch to power on the instrument.
2. Enter the timer/delayer mode:
Press
to step through the list mode and delayer setting interface.
Note: For the same channel, the timer function and delayer function are mutually exclusive. When the timer is
enabled, delayer is disabled. For different channels, they can be enabled or disabled at the same time.
3. Select the channel:
In timer/delayer mode, CH1, CH2, CH3, series and parallel can be selected as output channels.
When selecting CH1, CH2 or CH3, they can all work independently at the same time.
When selecting series or parallel mode, it can work independently with CH3, but CH1 and CH2 channels cannot
be used independently.
4. Connect the load:
Connect the load according to the selected load. Refer to chapter "Power Supply Series and Parallel
Connections" for the connection method.
5. Set list mode/delayer parameters:
Refer to the following chapters "List Mode Parameter Setting" and "Delayer Parameter Setting".
6. Turn on the output:
Press
of the corresponding channel to turn on the timing output.
