the step value. And then rotate the knob to adjust value; keep pressing [FREQ] softkey for more than 1 second to
change frequency unit.
4.1.5 Other parameters setting aresame as 4.1.14 (Keep pressing [OFFS], [DUTY] and [PHAS] to Initialize to
default values)
4.2 Introduction of measurement mode interface
