To query the voltage, current, and power measured on the output terminal of the channels using the VOLTCRAFT DSP Serie Single Channel DC Power Supply, you can use the following SCPI commands provided in the user manual:
1. **Query the voltage measured on the output terminal of the channel:**
- **Command:** MEASure:VOLTage?
- **Description:** Query the voltage measured on the output terminal of the channel.
- **Example:** MEAS:VOLT?
- **Returns:** 1.000 (Example output)
2. **Query the current measured on the output terminal of the channel:**
- **Command:** MEASure:CURRent?
- **Description:** Query the current measured on the output terminal of the channel.
- **Example:** MEAS:CURR?
- **Returns:** 1.000 (Example output)
3. **Query the power measured on the output terminal of the channel:**
- **Command:** MEASure:POWer?
- **Description:** Query the power measured on the output terminal of the channel.
- **Example:** MEAS:POW?
- **Returns:** 1.000 (Example output)
4. **Query voltage, current, and power at the output of the currently selected channel:**
- **Command:** MEASure:ALL?
- **Description:** Query the voltage, current, and power at the output of the currently selected channel.
- **Example:** MEAS[:ALL]? 1.000 2.000 2.000
- **Returns:** The voltage at the output terminal of the currently selected channel is 1V, the output current is 2A, and the output power is 2W.
5. **Query voltage, current, power, and running status of the output terminal of the currently selected channel:**
- **Command:** MEASure:ALL:INFO?
- **Description:** Query the voltage, current, power, and running status of the output terminal of the currently selected channel.
- **Example:** MEAS:ALL:INFO?
- **Returns:** 2.000 5.000 10.000 NR1 NR2 NR3 NR4
- The voltage at the output terminal of the currently selected channel is 2V, the output current is 5A, and the output power is 10W.
- NR1: Bool, output overvoltage: 1|ON means fault, 0|OFF means normal;
- NR2: Bool, output overcurrent: 1|ON means fault, 0|OFF means normal;
- NR3: Bool, output over temperature: 1|ON means fault, 0|OFF means normal;
- NR4: Integer, operating mode, 0 means standby mode, 1 means CV mode, 2 means CC mode, 3 means failure mode.
By using these SCPI commands, you can easily query the voltage, current, and power measurements on the output terminal of the channels of the VOLTCRAFT DSP Serie Single Channel DC Power Supply.
