Programming Examples

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

-> OUTP:DEL:FALL 1.0
