2. Press the Up/Down key or turn the knob to select the Parallel and press
[Enter].
3. Press the Left / Right key or turn the knob to adjust the value of this
parameter.
•
Single: Default value, indicates that the instrument is in single mode.
•
Master: Indicates that the current single unit is set to master in parallel
mode. When set to Master, you also need to set the number of slaves to
be mounted for the master, so you need to set the value of the Total pa-
rameter. For example, setting Total = 3 means that the total number of
units in the parallel relationship is 3.
In the parallel mode, you only need to operate the master. Synchro-
nous operations on other slaves are implemented by operating the
master.
•
Slave: Indicates that the instrument is set to the slave in parallel mode.
4. After the parameter settings are complete, press [Enter].
Before connecting the system bus, you must ensure that each instru-
ment is in single mode (Single).
Before connecting the cables, ensure that the instrument power switch
is off and the main of the AC power input (380V distribution box) is off.
For 3U models, up to 8 units of the same model can be connected in parallel.
Taking three 3U single instruments as an example, the steps for parallel opera-
tion are as follows.
1. Ensure that the power switches of the three units and the main switch of the
AC power distribution box are off.
