While all M1 Caliber Tools come with a factory calibration, an onsite calibration is recommended when first receiving the M1 to ensure the most accurate cuts possible and match your specific tape measure. Tape measures may vary based on manufacturer and class rating making it essential that a calibration is performed to match the specific tape measure blade printing. The following procedure allows the M1 to accurately convert rotary motion of the wheel to linear measurement that exactly match a specific tape measure. The following demonstration is made using wood but any material may be used should it meet the proper requirements and should match what you plan to most frequently cut with the M1 Caliber in order to ensure the most robust calibration.
At the bottom of this page you can download a printable version of these instructions as well.
Before beginning, ensure the following:
- The M1 is powered off
- The M1 is properly secured to the fence
- A flat, smooth, and straight piece of material at least 8 feet (2.5m) is available to use
- A trusted tape measure, at least 8 feet (2.5m) long, that will be commonly used, is available
- A sharp tip pencil or pen is available to make a mark
1) With the M1 powered off, turn on the M1 Caliber into calibration mode
- Hold both the zero and units button then click the power button once until "CAL" is displayed
- Be sure to only click the power button once and release immediately. Holding until the CAL displays on the screen will cause the device to power cycle and turn off.
- Screen will automatically transition the display from "CAL" to "ZERO" once buttons are released
2) Slide measuring material under M1 wheel until it is slightly past the blade location
3) Cut the material and select the zero button
The purpose of this cut is to ensure a straight reference edge.
- Note: Do not move material after you had made cut before confirming zero location.
4) Move material slightly to the right and ensure the material is stable on saw setup and select units (ft or m)
. 
5) Using a tape measure, make a mark on the material
- When calibrating in "ft" mode, mark exactly 6ft (72 inches) OR
- When calibrating in "m" mode, mark exactly 2m (200cm)
6) Slide material until mark meets the left side of the blade
Very carefully, ensuring the back of the board is always in contact with the fence, slide the material from left to right, until the left edge of the saw blade is perfectly aligned with the mark made in step (5).
Once aligned, select the zero button to confirm the calibration.
- Screen will display 72" in fractional mode for English calibrations
- Screen will display 78 3/4" in fractional mode for Metric calibrations
- Units can be changed to your preference in the next step
7) Verify your calibration to ensure it was completed successfully
Move material back to where cut was made. Screen should display very close to "0" confirming the calibration was successful.
- If not successful, carefully repeat above steps.

In the next and final article in this series, we will set up the M1 and make your first cut.

I got my M!. Thank you. But it's failing calibration. I can hold the buttons and it brings up CAL, but when I release them the screen blanks and nothing happens. Even the Power button doesn't work.
Hello Erich Thompson would you mind sending us a video at contact@reekon.tools and we would be happy to help get this solved for you!
