Call up output for display.
Read 0% output on display for
corresponding input pressure. For
analog transmission, check that
milliammeter reading is 4 mA (0%)
output.

Take SFC and milliammeter readings to
check that output signal does
correspond to zero and full-scale
pressures. 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.
