If the packaging carton or foam protection shows significant damage, do not discard it until the device and accessories have passed electrical and mechanical tests.

2. Check the Accessories:

Refer to "Appendix A: Accessories" in this manual to verify all supplied accessories are present and undamaged. If any accessories are missing or damaged, contact the distributor or local OWON offices.

3. Check the Complete Instrument:

If the instrument shows cosmetic damage, fails to operate normally, or does not pass performance tests, contact the distributor or local OWON offices. If damage occurred during transportation, keep the package and inform the transportation department or the distributor. Repair or replacement will be arranged by OWON.

3.3 Power Inspection:

(1) Connect the instrument to AC power using the supplied power cord.

Warning: To prevent electric shock, ensure the instrument is properly grounded.

(2) Press the power button on the front panel. The key light will flash, and the screen will display the measurement interface.

3.4 Output Inspection:

This inspection ensures the instrument achieves its rated outputs and responds correctly to front panel operations. Refer to "Turn On/Off the Channel Output" (page 8) and "Set the Output Voltage/Current" (page 8) for related procedures.

3.4.1 Voltage Output Inspection:

Verify basic voltage functions without load:

1. With no load connected, select a channel and ensure the output current setting is not zero.
2. Turn on the channel output and confirm the channel is in Constant Voltage (CV) output mode.
3. Set different voltage values on the channel. Check if the actual voltage displayed is close to the set value and if the actual current displayed is near zero.
4. Verify that the output voltage can be adjusted from zero to the maximum rating. A beep will sound when the maximum or minimum limit is reached.

3.4.2 Current Output Inspection:

Check basic current functions by shorting the power supply's output terminals:

1. Connect a short across the (+) and (-) output terminals using an insulated test lead suitable for the maximum current.
2. Set the output voltage to the maximum rating for this channel.
3. Turn on the channel output and ensure the channel is in Constant Current (CC) output mode.
4. Set different current values. Check if the actual current displayed is close to the set current value and if the actual voltage displayed is nearly zero.
5. Verify that the output current can be adjusted from zero to the maximum rating. A beep will sound when the maximum or minimum limit is reached.
6. Turn off the channel output and remove the short circuit from the output terminals.

4. Panel Operation

4.1 Turn On/Off the Channel Output

Press the On/Off key to turn the channel on or off.

4.2 Set the Output Voltage/Current

In the channel setting area, press the V / I key to move the cursor between voltage and current value positions. After selecting the value to set, turn the knob to change the value. Press the knob or the V / I key again to move the cursor.

Example Display: Set 05.00 V, 00.000 A

4.3 Over Voltage/Current Protection

Overvoltage Protection (O.V.P.) or Overcurrent Protection (O.C.P.): Once the output is turned on, if the output voltage/current reaches the set O.V.P./O.C.P. value, the instrument will cut off the output, and a warning will appear on the screen.

Note: When the instrument disables output due to protection, you must restart the channel after making adjustments for normal output.

This function protects the load by preventing the power output from exceeding the load rating.

In the channel setting area, press the OVP / OCP keys to move the cursor between parameters. After selecting the overvoltage/overcurrent protection value, turn the knob to change the cursor value, and press the OVP / OCP direction key to move the cursor position.

Example Display: Limit 31.00 V, 05.100 A

Note: When output current exceeds 10A, do not use banana plug connectors through the output terminal.

4.4 Memory key shortcut settings

3. Press the V / I / OVP / OCP key to enter the parameter setting state, and set the values for U (Voltage), I (Current), T (Duration), and Y/N (Selected).
4. In the parameter setting state, turn the knob to change the value of the current cursor. Press the knob or the V / I / OVP / OCP key to move the cursor position. Short press the Memory function key to exit the parameter setting status.
5. In the non-parameter setting state, press the knob for 3 seconds to confirm, enter the "List Waveform Output Mode", and return to the main interface.
6. Long press the Memory function key on the front panel for 3 seconds to exit the "List waveform editing interface".

4.5.2 List waveform output

To perform List waveform output:

• Restart the instrument after performing the above steps.
• If the problem persists, please contact OWON service.

2. The output is abnormal:

• Check if the output voltage is set to 0V. If so, set it to another value.
• Check if the output current is set to 0A. If so, set it to another value.
• When in programmable output status, check if any voltage/current value is set to 0. If so, set it to another value.
• If the problem persists, please contact OWON service.
