The auto calibration feature allows the user with Site Admin privileges to select a node, or group of nodes,
and remotely remove temperature differences between the ambient temperature and the setpoint (calibrate).
To auto calibrate WPTs:
| 1. | Click Advanced in the Menu bar.
|
| 2. | Click the Auto Calibration tab.
|

Auto Calibrating a Node Group
|
3. | Select whether you wish to auto-calibrate for a Node or Node Group in the Command by box. |
|
4. |
Click Go.
The Calibration Staus table with the existing Calibration Offset, the Control Pressure Used at Last Calibration, the calibrated Date, and the last Status is displayed. |
|
5. | Enter the desired control pressure in the Zone Control Pressure (PSI) field. |
|
6. | Click Calibrate Zone.
The Calibration Status table is updated with the current calculated Calibration Offset, the Control Pressure Used, the current Date, and the corresponding Status. |
|
7. | (Optional) In case of clearing out the existing auto-calibration offset from all nodes selected, click Clear Calibration. |
Note: The Default Calibration Setup can be accessed by the Setup button next to Zone Control Pressure field. The user can change global paramaters for calibration offset calculation with Save or Restore Factory Defaults button.

| • | Control Pressure: Default control pressure reference value. |
| • | Pressure Tolerance: The allowable difference between the control pressure specified and the actual branch pressure within the P-T Stability Block. |
| • | P-T Stability Block: The sample interval time to guarantee that the ambient temperature and the branch pressure do not change more than the tolerance amount. |
| • | Temperature Tolerance: The allowable difference among the ambient temperature values within the P-T Stability Block. |
| • | Sample Averaging Period: The entire time interval to be anlayzed for calibration calculation. |
