Sensor
ID
:
Unique identifier established by the user. Cannot be
the same as the serial number.
Sensor Serial Number:
Sensor serial number from the factory.
When you retrieve data and want to save it, the Sensor SN entry
will be suggested as a file name.
Coefficients:
Choose a Calibration Model for the sensors. For
instance, standard borehole piezometers would use VW_ABC
to specify a VW sensor using ABC Calibration factors. Choose
Single Channel. Enter ABC factors as noted on the sensor cali-
bration sheet.
Use ABC / TI factors:
These factors are used to convert Hz read-
ings to kPa or psi. TI factors integrate temperature readings to
automatically correct for temperature effects. See the sensor cal-
ibration sheet to see how the factors are applied.
