```Series connection of voltage source
You can deploy series connection of voltage source as shown below. The voltage output V 1
and V2 appear same as settings and a relationship with voltage and current is as below.
If V1 +V2 is within maximum voltage range（less than 250 V between Output and the earth on
GS-series) and load current IR is within a current limiter value, it is no problem to use.
At this time, ammeter A1 and A2 show same measured value（error is out of consideration）.

Parallel connection of current source
You can deploy parallel connection of current source as shown below. The current output
I1 and I2 appear same as settings and a relationship with voltage and current is as below.
If I1+I2 is within maximum current of cable/connector and load voltage V R is within voltage
limiter value, it is no problem to use.
At this time, voltmeter V1 、V2 show same measured value (error is out of consideration).

Parallel connection of voltage source
In case of parallel connection of voltage source, one source is overload for the other one.
（supposed to internal impedance of voltage source ≒0 Ω）
The output current I1 and I2 are balanced each other, or
either of them reach to the current limiter value and the other compensates for balancing.
Therefore, at this time ammeter A1 and A2 show different measured value.

Series connection of current source
In case of series connection of current source, one source is overload for the other one.
（supposed to internal impedance of current source ≒∞）
The output voltage V1 and V2 are balanced each other, or
either of them reach to the voltage limiter value and the other compensates for balancing.
Therefore, at this time, voltmeter V1 and V2 show different measured value.
