This is supplied by the manufacturer with an adjustment knob but this may have been removed by Martin Audio so that once
calibrated the controls can be covered with a label to prevent accidentally changing the calibration. If the knob is still present
carefully remove it as you will need it out of the way for the span calibration. Using a small screwdriver, adjust the control until
the read-out exactly matches the reference level.
Next raise the rear of the flying grid until the reference level reads approximately - 45⁰ (a downward tilt is shown as negative, an
upward tilt is positive);-
Take extreme caution handling the flying grid, it weighs close to 80Kg and injury could easily occur if it is dropped. Never
attempt to lift it on your own or without mechanical assistance and always ensure that it is adequately supported when lifting
the end to calibrate the span. Check the actual angle with your reference level and adjust the span potentiometer on the reader.
This is found through a small hole next to the zero adjustment pot and can be accessed with a small screwdriver or trimmer tool;-
