Calibration Of Key Sensor (Mpx70, Markiii); Error History - Yamaha Disklavier MX100A Product Handbook

5-6 Calibration of Key Sensor (MPX70, MARKIII)

The 1-beam continuous sensor on the MPX70 and the MARKIII includes a calibration function. In
most cases it is not necessary to perform calibration after the instrument has left the factory. But cali-
bration does need to be performed whenever the sensor unit is replaced.
To access this feature, select "SENSOR MEASURE" on the SENSOR SHEET menu. You can then
proceed as shown below.

Open: Remove the key stop rail, and lift up
each of the 88 keys once so that the
shutter does not obstruct the sensor
slit beam. (It is not necessary that
this be done simultaneously for all
keys.)
Rest: Put the 88 keys in the rest position.
End: Play each of the 88 keys once, low-
ering them (not too strongly, not too
softly) to the end of the stroke. (A
chromatic scale is sufficient.)
