3. After power-on, if the interface prompts “Chan Number Conflict”, rotate the

knob to change the channel number directly.

4.3.2 Synchronized Function (Link)

The user can set synchronized operation mode among multiple power supplies

connected via the system bus. There are the following two synchronized status.

• Online: indicates the instrument is in the synchronized relationship. At this

time, the front panel [Link] key light is lit.

• Offline: indicates the instrument is not in the synchronized relationship and

the front panel [Link] key light is off.

The user can select the following three synchronized modes.

• On/Off Only: set multiple units to output on/off and Save/Recall

synchronization.

When the Save/Recall operation is performed, the [Link] light of the oper-

ating device will be on, and the [Link] lights of other devices will be off.

• Track: besides output on/off and Save/Recall synchronization, you can set

the voltage proportional relation Reference among multiple power supplies

to make the voltage change proportionally. For example, set the voltage pro-

portional relation for three power supplies to 3, 4 and 5. If the voltage of the

first power supply is set to 30 V, the voltage of the other two power supplies

will change to 40 V and 50 V automatically.

In the Track mode, the Save/Recall synchronization is only effective for

the current setting value, and the voltage setting value is controlled by the

Reference.

• Duplicate: in this mode, the synchronized operations includes: output on/off

synchronization, voltage/current setting value changing synchronization,

Save/Recall synchronization, priority mode synchronization, voltage/current

rising/falling synchronization and Protect menu function synchronization.
