Sensor tracking issues

Before you continue reading, please check if your sensor has the latest firmware installed and if you are using the provided barbell strap in the case of using an Enode Sensor. Similarly, ensure the Bar Sensor Kit is properly placed inside the barbell sleeve. Additionally, many users suspect there are connection issues when reps are not being recorded, but we can assure you that there are none.

Like any other measuring device, the measurement technology within an IMU (the technology at work in our sensors) only works reliably within a defined range. Due to environmental influences, impacts, or strong vibrations, it can happen that measuring ranges are exceeded within the sensors. These out-of-range conditions cause the measured values to drift and lead to large deviations in the output data or even missed repetitions. 

In the following, we show the most frequent causes and suggested solutions in this context.

1. Minimum Distance: The minimum distance defined for the exercise and athlete is set too high. Lower it by at least 10 cm (approximately 4 inches) below your average distance, which you typically cover in this exercise. This setting is in place so that, for example, lifting the barbell out of a rack does not generate a repetition.
2. Maximal Inclination: If in an exercise with the equipment barbell, a maximum inclination of 20 degrees is exceeded, repetitions are automatically invalidated. Trap Bar Article (Enode Sensor only)
3. Velocity Threshold: If the velocity falls below a certain level (around 0.10 m/s), the sensor can't measure it and the repetition is considered finished. If the minimum distance has not been exceeded by then, no repetition will be registered. This usually only happens with close to 1RM attempts.
4. Impacts & Vibrations: Only one or a few repetitions of a set are recorded each set. The reason is in 99% of the cases impacts on the barbell or strong vibrations are caused by wobbly iron plates. Probably the best example here is the deadlift. When in doubt, try to let each repetition stand for itself by leaving a pause of up to 2 seconds between them while looking for the ready icon in the top right corner of the view. Pay attention to what you do with the barbell and the sensor before the start of a set. The data can drift if the barbell is rolled before lift-off or the hook of the rack is hit.
