3.3.29. V-monitor
V-monitor output signal is mainly designed connection to the oscilloscope, observe
UUT Voltage waveform, The V-monitor's signal is 0V to 10V. Please refer to Table
1-1, this signal is Proportional to the full scale current that the particular electronic
Load.
3.3.30. Analog programming input (Analog Input is an optional function)
The Electronic Load has an analog programming input on the rear panel of the
mainframe. The analogue programming input enables the load module to track and
load according to an external 0-10V (ac or ac + dc) signal.
The analog programming input is configured as a terminal on the mainframe's rear
panel.
The 3270 series Load will attempt to load proportionally according to the signal and
the load module's maximum current or power range. For example: 3270: Imax =
37.5A and Pmax =3750W
So in CC mode if analogue programming input is 5V = 18.75A load setting
Or in CP mode if analogue programming input is 1V = 37.5W load setting
In the Constant Current mode, 0V to 10V analog input signal can be set to 0A to full
scale of the load current to 3270 350V / 37.5A / 3750W electronic load , 10V analog
input signal can produce 37.5A load current.
In the Constant power mode, 0V to 10V analog input signal can be set to 0W to full
scale of the load power to 3270 350V / 37.5A / 3750W electronic load, 10V analog
input signal can produce 3750W load Power.
Note: The above operation must be LOAD ON
