11.4. Operating Modes
11.4.1. Read CV or CC Modes
The power supply may operate in the constant-voltage or constant-current mode. The
mode is selected automatically depending on the voltage limit, current limit and load
settings. The mode is not defined when the supply’s output is off
The CV or CC mode is shown on the supply front panel LEDs above the encoders
Syntax: SOURce:MODe?
Example: SOUR:MOD?
Responses: CV when in constant-voltage mode
CC when in constant-current mode
OFF when the output is off
11.4.2. Setting Local or Remote Modes
This command changes the power supply operation to local, remote or local-lockout.
The parameter may be a number or text as described below.
While the power supply is in local mode, the LAN communication may be used to
measure the power supply outputs and statuses. However, as soon as one LAN
command is used to change the supply output, the supply will automatically go into
remote mode.
See section 3.2 for further discussion of the local and remote modes.
Syntax: SYSTem:SET <0|1|2|LOC|REM|LLO>
Parameter:
Operate supply from front panel.
Measurements may be made remotely
Operate supply from LAN port.
Measurements may be made on front panel
Same as Remote, but front-panel
“Go to Local” button is disabled
Example: SYST:SET 2 (or SYST:SET LLO)
Query: SYST:SET? will return LLO in example
