4.2 General Inspection
After you get a new ODP Series power supply, it is recommended that you should make a
check on the instrument according to the following steps:
1. Check whether there is any damage caused by transportation.
If it is found that the packaging carton or the foamed plastic protection cushion has
suffered serious damage, do not throw it away first till the complete device and its
accessories succeed in the electrical and mechanical property tests.
2. Check the Accessories
The supplied accessories have been already described in the Appendix B
“Accessories” of this Manual. You can check whether there is any loss of accessories
with reference to this description. If it is found that there is any accessory lost or
damaged, please get in touch with the distributor of Lilliput responsible for this
service or the Lilliput’s local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
instrument can not work normally, or fails in the performance test, please get in touch
with the Lilliput’s distributor responsible for this business or the Lilliput’s local
offices. If there is damage to the instrument caused by the transportation, please keep
the package. With the transportation department or the Lilliput’s distributor
responsible for this business informed about it, a repairing or replacement of the
instrument will be arranged by the Lilliput.
4.3 Power-On Check
4.3.1 AC Power Input Setting
ODP Series adopt 110V/220V AC power source. Users should regulate the voltage scale
of the Power Switch according to the standards in their own country (see Figure 4-2) at
the rear panel and use an appropriate fuse.
11

4.Quick Start
Fuse
Voltage ODP3032 ODP3052
AC110V 125 V，F6 A 125 V，F10A
AC220V 250 V，F3 A 250 V，F5A
To change the input voltage scale of the instrument, do the following steps:
(1) Turn off the power button at the front panel and remove the power cord.
(2) Check if the fuse installed before leaving factory (250 V, F3 A) can match with the
selected voltage scale; if not, pry the cover open using a straight screwdriver (see ⑤
in Figure 4-2), change the fuse.
(3) Regulate the Power Switch to the right voltage scale.
4.3.2 Power On
(1) Connect the instrument to the AC supply using the supplied power cord.
Warning:
To avoid electric shock, the instrument must be grounded properly.
(2) Press down the power button at the front panel, the orange and blue key is lighted;
the screen shows the boot screen.
(3) Press any key to enter.
4.4 Output Inspection
Output inspection is to ensure that the instrument can achieve its rated outputs and
properly respond to operation from the front panel. For the procedures below, it is
suggested that you read “Working Mode” on P13, “Turn On/Off the Channel Output” on
P16 and “Set the Output Voltage/Current” on P16.
4.4.1 Voltage Output Inspection
The following steps verify basic voltage functions without load:
(1) When the instrument is under no load, power on it; make sure that the output current
setting value of each working mode is none-zero.
(2) Turn on the channel output. The ON/OFF and Volt/CV key is lighted, which
indicates the channel you opened is in Constant Voltage output mode.
(3) In each working mode, set some different voltage values; check if the actual voltage
value displayed is close to the set voltage value, and to check if the actual current
value displayed is nearly zero.
(4) Check that if the output voltage can be adjusted from zero to the maximum rating.
4.4.2 Current Output Inspection
The following steps check basic current functions with a short across the power supply’s
output:
(1) Power on the instrument.
(2) Connect a short across (+) and (-) output terminals with an insulated test lead. Use a
wire size sufficient to handle the maximum current.
12

4.Quick Start
(3) Set the output voltage to the maximum rating.
(4) Turn on the channel output. The ON/OFF and Curr/CC key is lighted, which
indicates the channel you opened is in Constant Current output mode.
(5) In each working mode, set some different current values; check if the actual current
value displayed is close to the set current value, and to check if the actual voltage
value displayed is nearly zero.
(6) Check that if the output current can be adjusted from zero to the maximum rating.
(7) Turn off the channel output and remove the short wire from the output terminals.
4.5 Working Mode
ODP Series are designed with four working modes: Independent, Parallel, Series and
Plus-minus. Press the Mode key to switch between the four working modes. For the
instructions of the user interfaces in the four working mode, please see “User Interface” on
P7.
4.5.1 Icons and Ratings
The status icons and voltage/current ratings of the four mode is listed below.
Independent Parallel Series Plus-minus
Status Icons
Voltage rating 0～30V 0～30V 0～60V 0～±30V
ODP3032
Current ratings 0～3A 0～6A 0～3A 0～3A
ODP3052
Current ratings 0～5A 0～10A 0～5A 0～5A
The 5V output terminals always output fixed 5V during the instrument is powered on, the
max output current is 3A (ODP3032) or 5A (ODP3052). Users could choose the proper
mode and output terminals as required.
