For the procedure in Table 43, we are assuming that piping arrangement
includes a block-off valve and a Tee-connector. If your piping does not
include a Tee-connector, you can only verify that the input and output
readings correlate.
Read Display or Action
Connect SFC across loop wiring and
turn it on. If possible, locate SFC where
you can also view receiver instrument in
loop. If you want to verify transmitter
output, connect a precision milliammeter
or voltmeter in loop to compare
readings.
Close block-off valve.
Remove plug from Tee-connector to
vent it to atmosphere, if applicable.

See Figure 38 for sample SFC and
meter connections in a typical
analog loop with a differential
pressure type transmitter.
See Figure 43 or 44 for sample
piping arrangement.
Allow system to stabilize at static
pressure.
