# Prodigit 3366G DC Electronic Load
|
|
|
|
Python RS-232 control tools for the Prodigit 3366G High Power DC Electronic Load (600V, 420A, 6000W).
|
|
|
|
## Setup
|
|
|
|
```bash
|
|
uv sync
|
|
```
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
# Identify the instrument
|
|
prodigit identify
|
|
|
|
# Take a single measurement
|
|
prodigit measure
|
|
|
|
# Monitor continuously (Ctrl+C to stop)
|
|
prodigit monitor --interval 1.0 --output data.csv
|
|
|
|
# Live graph
|
|
prodigit live --interval 0.5
|
|
|
|
# Set CC mode at 10A
|
|
prodigit set CC 10.0
|
|
|
|
# Turn load on/off
|
|
prodigit load on
|
|
prodigit load off
|
|
|
|
# Send raw command
|
|
prodigit send "MODE?"
|
|
prodigit send "CC CURR:HIGH 5.0"
|
|
```
|
|
|
|
## Serial Connection
|
|
|
|
Default: **COM1**, 115200 baud, 8N1, RTS/CTS hardware flow control.
|
|
|
|
```bash
|
|
# Use a different port or baud rate
|
|
prodigit -p COM3 -b 9600 identify
|
|
```
|
|
|
|
## Python API
|
|
|
|
```python
|
|
from prodigit3366g import Prodigit3366G
|
|
|
|
with Prodigit3366G("COM1", baudrate=115200) as load:
|
|
load.remote()
|
|
load.set_mode("CC")
|
|
load.set_cc_current(10.0)
|
|
load.load_on()
|
|
|
|
result = load.measure_all()
|
|
print(f"V={result.voltage:.3f}V I={result.current:.3f}A P={result.power:.3f}W")
|
|
|
|
load.load_off()
|
|
```
|
|
|
|
