18. When prompted to return the loop to automatic control, press ENTER
NOTE: If you are calibrating LRV and URV at the same time do not power down and start up
again after the LRV steps, just go to step 1 of the URV procedure below.

Correcting the Lower Range Value (URV) for Temperature

Assuming that you have just finished the LRV correct, then select the My Device menu, and choose
one of the following options:
1. Select the My Device menu, and choose one of the following options:
a) Device Setup \ Calibration \ PT Calibration \ PT URV Correct
2. You will be prompted to remove the loop from automatic control. After removing the loop
from automatic control, press OK.
3. When prompted, adjust the temperature source to apply value equal to the Upper Calibration
Point, and press OK.
4. When the temperature stabilizes, wait for 5 seconds, then press OK.
5. When prompted, remove temperature.
6. On the next prompt – "Please enter Calibration Date in MM/DD/YYYY format. Enter the

Minutes field MM (example "23"), and press ENTER.
9. When prompted to return the loop to automatic control, press ENTER
Note: When working with a Dual Input transmitter which has been configured for Differential
Input mode: Apply the Lower Calibration Point input and Upper Calibration Point input to both
inputs at the same time while performing the LRV and URV Corrects. Corrects will occur on
individual sensor readings when in Differential mode.
