This situation can be avoided using this command, which does not open the new board file, but
instead transfers everything except the hardware configuration from the selected board file into the
currently open board file. Therefore this command only loads the following:
• Sixteen parameters (e.g. configuration word, scale, auto-stop word) for each axis.
• Plot time of each axis.
• Axis name of each axis.
3.4.20 Scale/Offset Calibration Utilities
3.4.20.1 Using the Scale/Offset Calibration Utilities
The Scale/Offset Calibration utility provides an easy way to set the RMC’s mapping of transducer
counts to user-defined position units. This involves both the scaling, and if applicable, offsetting to
convert counts to position units, and defining the position unit range.
There are several Scale/Offset Calibration Utilities:
• Position Scale/Offset Calibration Utility
• MDT Scale/Offset Calibration Utility
• SSI Scale/Offset Calibration Utility
• Quadrature Calibration Utility
• Pressure Scale/Offset Calibration Utility
• Differential Force Scale/Offset Calibration Utility
3.4.20.2 Position Scale/Offset Calibration Utility
For a description of all Scale/Offset Calibration Utilities, see Using the Scale/Offset Calibration
Utilities. To use the general position Scale/Offset Calibration Utility:
1. Choose two axis positions to use for this calculation. These points should be significantly far apart
to minimize errors. Generally, the extend and retract limits are fine points to choose.
2. Place the cursor in a field under the position axis you wish to calibrate.
3. On the Tools menu, click Scale/Offset Calibration.
4. Move the axis to the first point. This can be done by jogging the axis manually, or by using the
Open Loop command.
5. Measure the physical distance to the first point on the axis in the position units that you intend to
use (for example, thousandths of inches, millimeters).
6. Under First position, in the Actual position box, type the distance measured to the first point in
position units.
