1 Pt Cal
The 1-Point Calibration allows you to adjust the current reading of the process value to match what the
actual value is as measured by some independent method (such as a laboratory measurement or
handheld instrument). The software will maintain the “4 mA =” setting used to scale the input, and
adjust the “20 mA =” setting to make the reading accurate at the value entered in the 1-Point
Calibration. A new window will open when you click the 1 Pt Cal button.
Current mA
Displays a live reading of the mA output of the transmitter.
Current Value
Displays the live calculated process value, using the existing 4 mA = , 20 mA = and Units
settings.
New Value
Enter the desired new reading for the process value, and then click Continue.
At the end of the calibration, the display will tell you if the calibration was successful or if the
calibration failed. If successful, click Close to resume control. If failed, refer to Section 8 for
troubleshooting help.
Reset Defaults
If for any reason you want to go back to factory default settings for the calibration coefficients, click on
the Reset Defaults button. You will be asked to verify that you want to change the calibration. Click
Yes to continue. Another window will pop up to tell you that the calibration was successful.
5.6 Digital Inputs
This page is used to configure the digital inputs. If you have set the type of input in the Startup page,
this page will already be showing the correct fields to set up each input type. If you have not already set
the input types, you can do that here, and then click the Submit button. When the page refreshes the
correct fields will appear.
Select the options that you want for each of the sections on the page. When you click on the “Submit”
button at the bottom of the page, your changes will take effect. If you move to another page without
clicking “Submit” first, your changes will be lost!
