Initiate shift key selection.
Read applied input pressure.
Prompt asks if the applied input
pressure equals zero input. If it is
zero input, go to next keystroke. If it
is not, press [
CLR] key to exit
function and try again.
Zero input is set equal to applied
input pressure.
10
Repeat Steps 6 to 8.
11
Close equalizer valve C.
12
Open valve B and LP block-off valve to
begin measuring process differential
pressure.
13
Take SFC and milliammeter readings to
check that output signal does
correspond to applied input 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.
14
Remove SFC and milliammeter from
loop.
