How do you set the blade width offset on the M1 Caliber?

Miter Saw
Accuracy

Kerf is the quiet error on a miter saw: zero the readout on the wrong side of the teeth and every piece comes out a blade narrow. The M1 Caliber lets the blade width be entered once, so zeroing sets the display to minus that figure and the cut lands on the number you actually asked for. From then on the reading at the fence is the finished length, which is what makes a run of parts repeatable rather than close.

How the offset gets set

Touch off on the teeth, not the plate
Enter blade width on the M1 once, 3/32 inch
Zero then reads minus the kerf
The M1 Caliber cuts to the number asked for
Checked against a tape at 36 inches

The blade is touched off on the left side, on the teeth, and zero is pressed. The blade offset is not yet entered, so it is held, toggled up to three thirty-seconds of an inch and zeroed again, which now reads minus three thirty-seconds. A thirty-six inch cut is made with a split blade, then checked against a tape and comes back at thirty-six inches.
