Close plug C
Open valve D to begin measuring
process line pressure.
Take SFC and milliammeter readings to
check that output signal does
correspond to applied line pressure. If
readings don't correspond, check that
transmitter has been installed correctly.
If applicable, blow down piping to be
sure no foreign matter is entrapped in it.
Check SFC and milliammeter readings
again. If readings are still not correct,
verify transmitter's configuration data
and change its range setting if needed.
Remove SFC and milliammeter from
loop.
