10.5 General Measurement
The measurement results of the general measurements are not recorded in the measurement report, but
all the specific measurements are based on the general measurements.
General measurements can be performed in the B mode, M mode, Color/PDI mode and PW mode. The
operations of Color/PDI mode and the B mode measurements are similar. These two modes measurements
are called BC measurement hereafter.
