For a description of all Scale/Offset Calibration Utilities, see Using the Scale/Offset Calibration Utilities. To use the MDT Scale/Offset Calibration Utility:
Gather the following pieces of information for an axis:
The gradient of the transducer and its units (e.g. 9.012µs/inch)
The number of recirculations for the transducer
The desired number of position units per inch or centimeter
The transducer counts at your desired zero position
Whether you wish to have your position units increase or decrease with increasing counts
For the axis you will be calibrating, make sure the No Transducer status bit is off. You may need to issue a 'P' command to turn the bit off. This will ensure the Counts values are read correctly from the RMC.
Place the cursor in a field under the axis you wish to calibrate.
On the Tools menu, click MDT Scale/Offset Calibration.
Enter the above pieces of information.
Under Extend/Retract Limits, choose how you wish to have the limits set:
If you had the extend and retract limits set correctly, click Use current limits, adjusted for new Scale and Offset to adjust the limits for your new Scale and Offset.
Otherwise, click Set limits to the following values and type the limits in the text boxes.
Click Apply, which sets the Scale, Offset, the Prescale Divisor bits of the Configuration word, Extend Limit, and Retract Limit.
Click Done.
Issue a 'P' command for the axis to have the new parameters take affect.
