Setup and Recording

#	Action
1	Power on the master crutch (default: right) and wait for services to start.
2	Connect a PC/tablet/smartphone to the master hotspot.
3	Open http://10.42.0.1:8000 in your browser (the Record page).
4	In the Status panel, click Update Datetime to immediately sync the master date/time.
5	Power on the slave crutch (left): it will auto-connect to the hotspot and sync time via NTP after about 1-2 minutes.
6	In the Status panel, verify that the main nodes are reachable (tip/handle/ppg, logger, coordinator; eye-tracker if used).
7	Run calibration in Calibration with the Calibrate button and check updated values/indicators. Note: keep the crutch lifted off the ground and do not press the handle, otherwise the offset calibration will be invalid.
8	(Optional) In the Eye-tracker section, click Connect and verify the status becomes Connected. Note: for discovery to work, the Pupil Neon must be paired with its smartphone, and must be connected to the same network as the master crutch.
9	Fill in Test Configuration fields (Subject ID, Session ID, Height, Weight, Crutch Height).
10	(Optional) Add notes in Comments.
11	(Optional) Click Condition and select the current condition.
12	Click Start to begin recording. Note: the condition can be changed during acquisition; the timestamp of each new condition is recorded.
13	During acquisition, monitor Status and confirm services/sensors are in a recording-consistent state.
14	If the condition changes during the test, use Condition again.
15	Click Stop to end the acquisition.
