how to tamper a PowerG sensor
Tampering any sensor refers to opening and removing the cover. This will release the tamper switch.

If you are trying to learn in the sensor, many PowerG sensors have an onboard learn button which should be used.
Are you attempting to pair the sensor? Or just testing the tamper function? What model of sensor?
