3.2 Parameter Usage and Selec-
tion
Before setting a parameter, please see the following
table for a summary of how and when each parameter
is used.
IMPORTANT
After setting and sending data with the HART
communicator, wait 30 seconds before turning
off the transmitter. If it is turned off too soon, the
settings will not be stored in the transmitter.

Range for 4 to 20 mA DC signal is set with actual input applied
Linear or Zero
Used to measure bi-directional flows
Sets a temperature unit displayed on HART communicator
Sets a pressure unit for the static pressure displayed on HART communicator
Used where installation conditions make it imperative to connect high pressure side
impulse line to low pressure side of transmitter

Sets a pressure unit for the measured pressure
Sets mode for output signal to “linear mode” (proportional to input differential pressure)
or to “Square root mode” (proportional to flow)
Adjust the output response speed for the input pressure of differential pressure
Used mainly to stabilize output near 0 if output signal is the square root mode. Two
modes are available: forcing output to 0% for input below a specific value, or changing
to proportional output for input below a specific value
Sets mode for integral indicator to “linear mode” (proportional to input differential
pressure) or to “Square root mode” (proportional to flow)
Sets the following 5 types of integral indicator scale ranges and unit: input pressure, % of
range, user set scale, input static pressure, % of static pressure range, and alternating
among any four of the above
Used for loop checks. Output can be set freely from –2.5% to 110% in 1% steps
Check using the self-test and status command. If an error is detected, the corresponding
message is displayed
Displays the permit/protect status of setting changes depending on communications
Write protect status is released for 10 minutes when the password is entered
