Chapter17 Programming Examples
This chapter displays the programming examples to remotely control IT-M3100
power supply using SCPI commands.
Note
⚫
If the user want to change the settings of the instrument, for instance, the output
setting value, the command SYST:REM must be sent to the instrument after
finishing the connection between the instrument and PC.
⚫
“ - >” indicates the commands that you send to the IT-M3100 power supply.
Example1: Identifying the Power Supply in Use
You can verify whether you are communicating with the right IT-M3100 power
supply.
To query the identification of the power supply, send the command:
-> *IDN?
To check the power supply error queue, send the command:
-> SYST:ERR?
Example2: Setting the Common Output Arguments
To set the output voltage to 10 V, send the command:
-> VOLT 10.00
To set the output current to 3.5 A, send the command:
-> CURR 3.500
You can also the following command to set the output voltage to 10 V and set
the output current to 3.5 A simultaneously:
-> APPL 10.00,3.500
To select the voltage priority mode or current priority mode, send the command:
-> FUNC:PRI VOLT|CURR
To set the delay time to 1 second before turning the output on, send the
command:
-> OUTP:DEL 1.0
To set the delay time to 1 second after turning the output off, send the
command:
-> OUTP:DEL:OFF 1.0 or -> OUTP:DEL:FALL 1.0
