Analog Output Parameters
The output signal of transmitter is a 4-20mA current which in normal condition represents the
current value of primary variable. If the value of primary variable be out of range or the device
conclude that there is a fault in electronic boards or sensor module that takes the device into
mal-function mode, the output signal will represent the alarm condition.
User can simulate and/or trim the output signal using CUR and CTR menu items.

Alarm
(setting alarm for
over range, under
range or holding the
last value)
Press <M> until this page is appeared on LCD. Then press
<Z> to access the Alarm parameters (programing mode).
You can set the alarm for over range (high) and under
range (low) or maintain the last value (Last) by pressing
<S>. After that, press <Z> until all characters blink. Then
press <M> for the saving new parameter and switching
from programing mode to operation mode.
Test/Trim
Current
(Simulate the
output current to fix
value and/or trim
the current)
Press <M> until this page is appeared on LCD. Then press
<Z> to access the test current value (programing mode).
You can change the amount of digits by <S> and change
the point and position of digits by <Z>. After tuning this
parameter, press the <Z> until all characters blink. Then
press <M> for apply this value to as output current. By
pressing <M> display module go to trimming mode. You
can enter the actual value which you read via series multi-
meter and press <M> key to save new parameter and
switching from programing mode to operation mode.
In any state to exit from simulating current mode you can
enter zero value as test current value or restart the
transmitter.
Communication Parameters
FT3351 Series transmitter supports Hart multi-drop mode. To identify the device ID in this
mode, user can use the POLL ID menu.
