2-2 Units of Angular Measurement •See page 28 for full details on specifying the unit of angular measurement. •Once ydu specify a unit of angular measurement, it remains in effect until you specify - a different one. The specification is retained even if you switch power off. •The following calculations cannot be performed in the BASE Mode. Example Result displayed in degrees. To convert 4.25 rad to degrees.
