5 – A Calibration
LDM – 110
All units are calibrated at Takikawa Engineering using XXX gage pins traceable to NIST.
If you need to recalibrate the unit for a specific application, please follow these
instructions.
Note: Two XXX gage pins will be required. Normally, these encompass the full
measurement range of the laser sensor.
Recommended gage pin sizes for Calibration:
1. Select the large pin (example: 0.5000 inch).
2. Set Reference preset to pin size (in this example 05000).
3. Place the large pin in the center of the laser beam.
4. Using a small blunt instrument, depress the CAL H switch on the front panel of
the LDM processor and hold it. 8.8.8.8.8 will be displayed and will then switch to
the pin size (0.5000). When the pin size is displayed release the switch.
5. Remove the large pin and replace it with a small pin (example: 0.0200 inch)
6. Repeat steps 2 through 4 using the small pin and the CAL L switch.
7. The calibration procedure is now complete
