Orange VT1000 Valve Tester Acclimation

Certain users have reported that they get different readings from the same vacuum tube after the VT1000 Valve Tester has been moved. According to Orange, this is to be expected; the tube analysis system in the VT-1000 is sensitive to temperature. For best results, after moving the unit to a new location allow it to acclimate for 1.5-2 hours before using it to test a tube, particularly if there is a temperature difference between the two locations or if the unit has been exposed to varying temperatures during transport.
