Trimming
Trimming applies to the following I/O modules: AIM,
TIM, and AOM. Each channel can be trimmed with
two data points within the selected zero and span
measurement range. Input trimming allows a complete
range to be monitored, while placing a measurement
emphasis on the most critical segment of the process
range. Output trimming alters the output of the AOM
to match a specific input device or display.
Trimming both Input and Output can be achieved
using either the Web Interface or the PC Configuration
Software. Both methods are nearly identical see
following for instructions:
Input (Sensor) Trimming Using the Web Interface
To perform sensor trimming, follow the steps below.
1. Select the channel you wish to trim; click the
Trim / Enable link on the associated web page.
2. Click the Trimming enabled checkbox.
Depending on your function, select 1 point trim
or 2 point trim.
3. To trim the lower point, enter the value that you
would like displayed as your process variable (PV)
into the Lower text box.
4. Click the Trim Lower button. This will bring up
a pop-up window prompting you to input the value
that you entered as your lower trim point; click
Next when the value is input and has stabilized;
click Accept if you are satisfied with the data
received by the Input Module. The captured value
will update to this value on the Analog Input
Trimming screen.
5. If performing 2 point trimming, repeat Steps 4
and 5 for the upper trim point.
6. Click Submit to save the trimming values and
continue to the next channel.
Repeat these steps for each channel that requires
trimming.
Output Trimming Using the Web Interface
To perform output trimming, follow the steps below.
1. Select the channel you wish to trim; click the
Trim / Enable link on the associated web page.
2. Click the Trimming enabled checkbox.
Depending on your function, select 1 point trim or
2 point trim.
3. To trim the lower point, enter the value
corresponding to your process variable (PV) into
the Lower text box.
4. Click the Trim Lower button. This will bring up
a pop-up window allowing you to adjust the output
in either small, medium, or large increments. The
value can also be directly set. Observe the
connected sensor or display; when you are
satisfied with the reading on the measuring
device, click Accept. The captured value will
update to this value on the Analog Output
Trimming screen.
5. If performing 2 point trimming, repeat Steps 4
and 5 for the upper trim point.
6. Click Submit to save the trimming values and
continue to the next channel.
Repeat these steps for each channel that requires
trimming.
