FAQ

• How does one increase the measurement accuracy of the outer diameter?

  Try to aim the Placement Cursor precisely on the circumference of the real flange. The smartphone must remain stationary while clicking on the Accept Button. The three points to be selected should form an arc of at least 180º. Maintain the smartphone parallel to the flange plane to reduce the deviation arising from the viewing angle.

• How does one increase the measurement accuracy of the bolt circle diameter?

  Ensure the bottom circumference of the red cylinder precisely passes through all the bolt centers on the flange. In addition, maintain the smartphone parallel to the flange plane to reduce the deviation arising from the viewing angle.

• How does one increase the measurement accuracy of the flange thickness?

  Try to precisely match the yellow cylinder with the real flange. Hold your smartphone perpendicular to the flange plane to reduce the deviation induced by the viewing angle.
