Example:
The present output voltage is at 20.00V, and the wheel knob status is
at normal, the SV+<cr> message is sent to the power supply, the
voltage of which will become 21.00V.
*SV-
Function:
Subtract one unit from the present voltage setting.
Syntax:
SV-<cr>
HEX = 53 56 2D 0D
Explain:
When the message of SV-<cr> is sent to the power supply from
computer, the power supply will subtract one unit from the present
voltage setting immediately.
Example:
The present output voltage is at 20.00V, and the wheel knob status is
at normal, the SV-<cr> message is sent to the power supply, the
voltage of which will become 19.00V.
*SU+
