Installation notes
The PACE1000 pressure indicator requires a set of connections with the exception of the
reference connection, this provides a reference to atmosphere for gauge sensors and
barometric sensors.
The gas density and type does not affect the accuracy of pressure measurement, assuming
that the UUT is at the same level (height) as the indicator or gas head correction is
accurately set.
