Multi-Machine Operation

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

synchronization.

• 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

proportional 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.

This function requires multiple instruments to be in CV priority mode at the

same time, otherwise the voltage setting proportionally is not effective. Before

using this function set all units to CV priority mode.

• 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.

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.

You can enter into the system menu to set the status(Online/Offline) of the

instrument, or you can short press (1 s or so) the front panel [Link] key to

switch the synchronization status of the instrument. Long pressing (about 3 s)

[Link] key can display the current synchronization status of the instrument. At

this time, pressing [Enter] key can enter into the synchronization menu setting

interface. You can set parameters such as synchronized mode or On/Off delay

time.

Take the synchronized relationship among single instrument and multiple

parallel groups for instance, the detailed connection method and procedures

are as follows.
