- It is a good idea to wait about 5 minutes after putting the electrode on for the skin-gel interface to stabilize, before you start calibrating.
- If your leg is cold (for example, if you come in from the outside during winter), you should wait 30-60 minutes so that your leg warms up to room temperature before calibrating. The reason is that cold will artificially elevate the sensation threshold (the same reason cold makes you feel numb).
- Do not calibrate right after a therapy session (of >30 minutes) because the sensation threshold will be artificially elevated. You should wait at least 1 hour and preferably 2 hours after a therapy session.
