This page contains instructions on how to calibrate the speed for the Elite E8i.
The NoblePro treadmills are calibrated during the manufacturing process and are normally accurate within +/-0.5 km/hr. The calibration of the speed is however not static as factors like belt stretch and components seeding or wearing out over time will effect the readings.
It is therefore recommended to calibrate your treadmill from time to time to ensure the more accurate data is captured for your session.
Note: This procedure is for advanced users and to be undertaken at one’s own risk.
To ensure accurate calibration of the speed you will need a measuring instrument called a tachometer. We recommend using one of the following tachometers:
Sealey TA050 Digital Tachometer – Amazon Link OR Protmex Digital Tachometer (MS6208A) – Amazon Link
It is not recommended to calibrate the treadmill speed using any other device as accuracy is likely going to suffer as a result.
1. Start the treadmill and record the speed using the recommended tachometer at 1 km/hr, 10 km/hr and max speed.
Note: Ensure you follow the tachometer manufacturer’s user’s manual to measure in km/hr using the correct attachment. If the device does not measure in km/hr ensure to convert the values accordingly.
2. On the treadmill touch screen open Settings>Advanced Settings.
This alternative speed measuring method counts the belt revolutions per minute and estimates the speed.
1. Set the treadmill speed.
2. Count the number of times the belt has completed a revolution in 60 seconds.
3. Use the table below to estimate the belt speed.
| Speed (km / h) | Belt revolutions per minute |
|---|---|
| 1 | 5.3 |
| 9.8 | 52 |
| 10.2 | 53 |
| 19.8 | 105 |
| 20 | 106 |
| 20.2 | 107 |
3. Adjust the value up by one if the speed needs to be increased or down by one if it needs to be decreased for the respective value.
The recommended starting values are:
1 km/hr = 90
10 km/hr = 95
20 km/hr = 92
4. Save changes.
5. Repeat step 1-4 until the measured speed is within +/-0.5 km/hr of the target speed of the treadmill.
6. Turn the treadmill off and on at the power plug and check that the readings have been saved by measuring the speeds at 1, 10 and max km/hr and checking the values.
7. Congratulations! Your treadmill speed is now calibrated.
1. On the treadmill touch screen open Settings>Advanced Settings.
2. Click Reset
3. Click Save
This incline calibration is automated for the Elite E8i. Go to Settings>Advanced Settings then click on the Auto Calibration. This will automatically incline, decline and calibrate the treadmill then save the new settings.
Belt speed inconsistent at a steady speed. The calibration values are out of bounds. Reset and save the default values.
Speed shoots up or down. The calibration values are out of bounds. Reset and save the default values.
