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 if you are using an Enode Sensor. Respectively, check the Bar Sensor Kit is properly placed inside the barbell sleeve. Furthermore, many users suspect there are connection issues when reps are not getting recorded, but we can assure you there are not.
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.
- The minimum distance defined for the exercise and athlete is set too high. Lower it at least 10 cm (4 inches) below your average distance, which you typically cover in this exercise. This setting is there so that, for example, lifting the barbell out of a rack does not generate a repetition.
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)
- 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.
- 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.
If all the above tips do not lead to any improvement, you can always contact us. The more information you provide, the more likely it is to find a solution. The most helpful is usually a video where the problem occurs. But also data exports or screenshots can help to find a solution. If none of these are an option, we should at least know which exercises the issues typically occur on.
