Running a Test
Before you start
Section titled “Before you start”- The plate is connected and the live preview shows a stable baseline
- The athlete is off the plate
- The plate has been tared (Device screen → Tare)
- An athlete profile is selected
Starting a test
Section titled “Starting a test”- On the Testing screen, select the athlete

- Set start delay (countdown before capture begins) — default 3 s
- Set test duration — or leave on Auto-stop
- Tap Start
During the countdown, the athlete stands still with one foot on each measuring surface. The app uses this quiet standing period to estimate bodyweight.
During capture

- Stop manually at any time by tapping Stop
- Auto-stop triggers when force returns to near-zero after the jump (CMJ / SJ / Drop Jump)
After capture
Section titled “After capture”Results are calculated immediately and displayed:
- Key metrics panel (peak force, jump height, impulse, RSI, etc.)
- Force-time chart for the full session
- Ability to retake or save
Tap Save to store the session. Saved sessions sync to Hootuo Cloud automatically.
Retaking a test
Section titled “Retaking a test”Tap Retake to discard the current capture and start again. The athlete should step off the plate and re-tare if more than a few minutes have passed.
