Notes:
1 The Frequency reading is corresponding to the current or voltage input signal respectively. The Frequency measurement
is always working on autoranging mode. The Buttons of AUTO, UP and DOWN are used to select the range of measuring
signal. If the current measurement is set before selecting Hz function, the default will show ACI first, else show ACV.
2 In autoranging mode, the ranges setting of both the primary and secondary display are
corresponding to the higher range of two displays. Whereas in manual range, the ranges of
secondary display are the same as the primary display.
