Multi-Machine Operation

a. Connect system bus interfaces.

b. Connect the DUTs. Refer to 2.5 Connecting the Device Under Test

(DUT) for more information about connection methods.

c. Connect the instrument to PC. refer to 2.6 Connect the Communication

Interface.

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

knob to change the channel number directly.

8.2 Synchronized Function (Link)

By operating one unit in the System Bus link locally or remotely, it is possible to

synchronously control the On/Off and equal-scale output of the other units. The

synchronization function and On / Off Delay function can be used together to

realize the application of timing output.

Before configuring the synchronized function, each instrument must be set to

a separate channel number ranging from 1 to 16. refer to 8.1 Multi-Channel

Function .

There are three synchronized modes as follows:

• 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:
