Calibration
There are three typical variations of calibration. The first variation (Type 1) is for the DRO to show the sanded thickness of
the material. The second variation (Type 2) is to show how much stock is being removed with each pass of the sander.
Another method (Type 3) to show the amount of material being removed per pass without recalibrating the Type 1 setting.
Type 1 Calibration ABS:
Calibration for the DRO to show sanded thickness (Type 1). Calibration is quick and easy and requires no extra measuring
device. Make sure the machine is turned OFF and power is disconnected!
1. Wrap the sanding drum with the desired grit abrasive.
2. Lower the sanding drum until it lightly touches the conveyor belt.
3. Turn “ON” the DRO.
4. Hold the “CAL” button 3 seconds until “0.00” appears.
Type 2 Calibration ABS:
Calibration for the DRO to show stock removed per sanding pass (Type 2). Calibration is quick and easy and requires no
extra measuring device. Make sure the machine is turned OFF and power is disconnected after the first step!
1. Sand a test piece of stock until it is flat and uniform on both sides.
2. Turn the Sander OFF and disconnect power to sander.
3. Position the sanding drum (with abrasive still wrapped on drum) on the test piece until the drum is lightly touching the test
piece.
