Blinks quickly: Operation is disabled although the start command is given.
(d) Unit indicator
Hz: ON when the actual frequency is monitored. (Blinks when the set frequency is monitored.)
A: ON when the current is monitored.
(e)
Monitor display (4-digit
LED) Shows a numeric value (readout) of a monitor item such as the frequency or a parameter number.
(The monitor items can be changed according to the settings of
