6.2.5 Difference
Difference is a pressure related function: this allows the difference between the internal pressure
sensor reading and the external pressure sensor reading to be displayed on the calibrator task
screen. An external pressure sensor must be connected to see the resulting pressure reading.
Note:
Care should be taken when both sensors are not the same type (absolute/gauge) to ensure
that the contribution from atmospheric pressure has been considered.
