Operation
Plug it in, and wait for the sensor to warm up. The status light blinks according to the sensor status:
| Code | Color | Status |
|---|---|---|
| 0 | White/Black | Idle/off |
| 1 | Red/White | Cell heating |
| 2 | Yellow/Red | Pump locking |
| 3 | Purple/Red | Probe locking |
| 4 | Blue/White | Lasers locked; no signal |
| 5 | Green/White | Operational |
The status code is also reported as the status byte in the data stream.
