Measurement Definition
Nominal Offset
A nominal offset is similar to the “nominal” sensitivity of the sensor, such as
“100 mV/g”, which is often used in place of the provided specific sensitivity of
the sensor, such as “98.4 mV/g”. You can enter a nominal value when a precise
measurement is not necessary, when the precise sensitivity is not known, or
when it is desired or necessary to be able to replace a sensor without having to
modify the configuration.
Nominal offset values are available only for sensors that are provided by
Rockwell Automation and as provided in the following table. For other sensors,
a Specific Offset must be provided.
For the installed sensor, enter the offset as provided in the following table for
the selected engineering units.
Specific Offset
When a nominal offset is not known, or if a more precise measurement is
necessary, then a specific offset can be determined as follows.
On the DC Page for each AT sensor, verify that the Calibration Offset is 0.00.
