Why do I perform a Spin Down Calibration?

Get the best out of your VOLT by keeping it in top condition.

The JetBlack VOLT™ EMS Smart Trainer power accuracy has been designed for best performance with a Spin Down Calibration. To get the most accurate readings we suggest using the JetBlack App to complete a Spin Down Calibration (you will find this in the ‘Settings’ page). DO NOT USE THIRD PARTY SPIN DOWN CALIBRATIONS; this will damage your VOLT™.

Heat plays a big part in the accuracy of your power readings. The warmer the trainer before spin down, the more accurate your readings will be.
