2.5.4 Calibration Tag Survey and Configuration
After the location of a Calibration Tag has been finalized, survey its position using the same approach
that was used to survey Reader locations. Record the Tag ID and X, Y, Z coordinates for each
Calibration Tag.
Continue to place and verify Calibration Tags until one or more groups of Readers has been covered
with adequate overlap. Use the PLUS Installation Worksheet to record Calibration Tag IDs and
location data.
Open the Tag Configuration window from the Visualizer Settings menu. Locate the ID of each
Calibration Tag, and under the Cal Tag column, select Yes. Under the X, Y, and Z columns, enter
the surveyed coordinates for the Tag. Be sure that the units match the selected English or Metric
settings. Verify that only the Calibration Tags in the list have Yes selected under the Cal Tag
column. When finished, close the Tag Configuration window and save the configuration.

2.5.5 Calibrate the System
After Calibration Tags have been placed and verified for one or more groups, follow the procedure
below to calibrate those groups.
1) On the button toolbar, click the Calibrate button to open the Calibration window.
2) Select the desired group, or set of groups, and move them to the Calibrate text box using the
direction arrows. You may wish to click the Display selected radio button to only show these
groups in the map display.
3) In the Calibrate frame, enter a Duration of 10 or greater. Longer calibrations (up to 60 seconds)
are preferable, but make sure that the environment is not changing during the calibration interval.
Calibration intervals of less than 10 seconds may result in less accurate results.
