Background Measurements

The background measurements fields on the survey metadata forms have special
behaviour, pressing the input field triggers the UltraTEV Plus² to start measuring the TEV
level for a ten second period. Following this, the average measurement for the period is
stored. When performing the Background Metal measurement, the TEV plate of the UltraTEV
Plus² should be held against an unearthed piece of metalwork in the substation not
connected to the switchgear. The Background Air measurement requires holding the
instrument in free space in order to get an ambient reading.
The background temperature and humidity is taken directly from the current measurement
by the temperature sensor. Please note that the sensor needs to be connected to the
UltraTEV Plus² device.
