When to calibrate
Calibration gives the app a clean baseline for the person, muscle, side, and placement you are measuring. Recalibrate when any of those variables change enough to affect the reading.
- Before the first sensor session with a new client.
- When switching to a new muscle group.
- When switching from left side to right side for a comparison.
- If readings look inconsistent despite stable technique.
- After a long break from measuring that muscle.
Calibration best practices
- Place the sensor before calibration and avoid moving it afterward.
- Ask the client to stay still until calibration finishes.
- Use the same body position you will use for the movement when practical.
- Record the placement if you plan to compare the same muscle across future sessions.
What changes the baseline
Sweat, sensor pressure, skin products, placement drift, fatigue, and different joint angles can all change the signal. If the setup changed, treat the next reading as a new comparison rather than a perfect continuation.
