What is Involved in a Calibration

What is involved in a calibration of a Lode Ergometer (and how long does it take)

In this article, we’ll go through everything involved in calibrating a Lode ergometer, from the physical process, what needs to be completed beforehand, the equipment and the required logistics to successfully complete your calibration.

  • Before your calibration
    • Complete the provided pre-calibration form which gives your service engineer important information about your ergometer
    • Ensure there is at least 3m of space around the ergometer in all directions
  • Calibration Procedure (the process is expected to take 3 hours per ergometer and we usually block out a half day in total to allow for things such as set up/pack up)
  1. A Logemas technician will attend your site with the calibration machine and the relevant tools
  2. A visual and functional checklist will be completed
  3. The Logemas technician will update the firmware if your ergometer requires it
  4. The calibration machine is connected to your ergometer via an axle attached to the ergometers the bottom bracket, this is the bracket that connects your pedals and crank arms to the bike itself. (note: the ergometers crank arms will need to be removed by the technician)
  5. The technician will run through a series of conditions (various combinations of RPM and Watts)
  6. The technician then modifies the calibration settings of the bike
  7. A verification process is then completed by running through the same series of conditions as before to confirm an improvement in accuracy.
  • Equipment brought by Logemas
    • Calibrator inside a travel case
    • Travel bag containing required tools
    • Laptop with service software
  • Logistics
    • The service engineer will need somewhere on-site to park their vehicle, preferably close to the ergometer location
    • The calibrator travel case weighs approximately 55kg and though it has wheels it is best to avoid stairs

Other important information:

  • If calibrating multiple ergometers it is often easier to swap out the ergometers rather than reposition the calibrator multiple times
  • Ergometers that have not been calibrated within the recommended 12 month period can have unforeseen issues during the calibration process even if they work perfectly during normal use, the chance of this occurring increases with the length of time between calibrations/services.
