SU+
Function: Add one unit to the present voltage limit setting.
SU+<cr>
Syntax:
Explain: When the message of SU+<cr> is sent to the power supply from
computer, the power supply will add one unit to the present voltage limit
setting immediately.
Example: The present voltage limit is at 30V, and the wheel knob status is at
normal, the SU+<cr> message is sent to the power supply, the voltage
limit of which will become 31V.
SU-
Function: Subtract one unit from the present voltage limit setting.
Syntax: SU-<cr>
When the message of SU-<cr> is sent to the power supply from
Explain:
computer, the power supply will subtract one unit from the present voltage
limit setting immediately.
Example: The present voltage limit is at 30V, and the wheel knob status is at
normal, the SU-<cr> message is sent to the power supply, the voltage
limit of which will become 29V.
SI+
Function: Add one unit to the present current limit setting.
Syntax: SI+<cr> HEX = 53 49 2B 0D
When the message of SI+<cr> is sent to the power supply from computer,
Explain:
the power supply will add one unit to the present current limit setting
immediately.
Example: The present current limit is at 3.00A, and the wheel knob status is at
normal, the SI+<cr> message is sent to the power supply, the current limit
of which will become 3.10A.
