The wristband does not require manual calibration
As the wristband is not an “absence of voltage tester” it does not require manual calibration.
The wristband settings are calibrated every time that the wristband connects to the Proxxi Voltage App (as long as there is an internet connection) to ensure that the wristband is alerting appropriately to different electric field strengths.
At this time, settings are not calibrated when connected to the Proxxi Hub App
