First Use DP1308A
Before operating, please do perform necessary inspections to ensure the instrument is
in a good position to work normally.
Power Requirement
Four types of AC power within 50Hz-60Hz of frequency are provided by DP1308A:
100V, 115V, 220V, 230V. You can choose an appropriate input power as required
through switching the “Power Voltage Selector”on the rear panel.
WARNING
Before switching the “Power Voltage Selector”, make sure that the power
supply has been cut off and the instrument has installed specified fuse.
Power-On Inspection
Please use the power cord listed in accessories to connect the instrument with AC
supply, and then perform the following instructions:
1. Turn on the instrument
Turn on the power switch on the rear panel. (At present, the instrument has
connected to AC supply.)
WARNING
To avoid electric shock, make sure that the instrument has properly grounded.
2. Turn on the power button
Press down the power button on the front panel to enable the self-test. If
pass test, the user interface will appear on screen, or else a clue “System
power-on self-test has a mistake, view the error or not?”will pop up, press OK to
get more information about fail, or press Cancel to exit clue.

Output Inspection
In virtue of this function, the instrument enables to respond to front panel correctly
and output rated value. The inspections are mainly centered on the voltage output on
the occasion of no loads for each channel and the current output when short
circuit.
1. Channel selection and output switch
Choose an appropriate output channel using selection buttons. The selected
channel will be highlighted on screen.
Figure 1-4 Output channel selection
Turn on/off the output by pressing On/Off button under the selection button of each
channel. After you enable the output of a channel, the corresponding button will light
until you disable the output regardless of whether it is the current channel or not.
2. Voltage output inspection
(1) When the instrument has no load: Press power button and make sure that
the setting value of current in each channel is not 0;
(2) Inspect “all on”and “all off”function of channels;
Press All On button, then a clue about whether to open output of all
channels will appear on, if click ok, all the channel buttons light will go on
that denotes they are ready to output; on the contrary, the instrument backs
to the state before.
Press All Off buttons to disable the output of all channels. Meanwhile, the
corresponding On/Off button is black out.

(3) Inspect the voltage function of +6V channel;
Press +6V button and the corresponding On/Off button, the channel will be in
constant voltage output state after On/Off button light goes on, then check
whether the “voltage”can be adjusted from 0 to the maximum rated value(6.3V).
See the “Parameter Input”section in chapter 2.
(4) Inspect the voltage function of +25V channel;
Press +25V button and the corresponding On/Off button, the channel will be in
constant voltage output state after On/Off button light goes on, then check
whether the “voltage”can be adjusted from 0 to the maximum rated
value(26.25V).
(5) Inspect the voltage function of -25V channel;
Press -25V button and the corresponding On/Off button, the channel will be in
constant voltage output state after On/Off button light goes on, then check
whether the voltage can be adjusted from 0 to the minimum rated
value(-26.25V).
3. Current output inspection
(1) Press the power button .
(2) Press All Off button to disable the output of all channels.
(3) Inspect the current function of +6V channel.
Short the terminal (+) and (-) of +6V channel using an insulating output
lead;
Press +6V button;
Set the voltage as 6V;
Press the corresponding On/Off button of +6V channel;
After On/Off button light goes on, check whether the “current”can be
adjusted from 0 to the maximum rated value (5.25A).
(4) Inspect the current function of +25V channel.
Short the terminal (+) and (COM) of +25V channel using an insulating
testing lead;
Press +25V button;
Set the voltage value as 25V;

1-10
Press the corresponding On/Off button of +25V channel;
After On/Off button light goes on, check whether the “current”can be
adjusted from 0 to the maximum rated value (1.05A).
(5) Inspect the current function of -25V channel.
Short the terminal (-) and (COM) of -25V channel using an insulating testing
lead;
Press -25V button; set the voltage value as -25V;
