Chapter4 Waveform Display Function
This chapter describes the features and use of the waveform display function of
the IT9121 power meter in details.
4.1 Basic Concepts
The IT9121 power meter has a waveform display function based on sampling
data. The voltage and current waveform of the input unit can be displayed or
hidden. Only the necessary waveform is displayed to facilitate observation. The
waveform display interface includes the vertical axis and the horizontal axis.
Introduction of soft keys on the interface
When the
button is pressed, the initial waveform display interface
below appears.
Description of information of waveform display interface:
Parameter name
Parameter descriptions
U_RANGE
Voltage range setting: press the soft key
corresponding to this parameter to set the voltage
range.
I_RANGE
Current range setting: press the soft key
corresponding to this parameter to set the current
range.
RUN/STOP
Run/stop: press the soft key corresponding to this
parameter to run or stop the waveform status.
SINGLE
Single measurement key: when single
measurement is performed under stop conditions,
the stop status will be enabled again after one
measurement according to the current data
updating rate. When single measurement is
performed under running conditions, one
measurement will be performed immediately by
the instrument and then the stop status will be
enabled.
SCOPE(U/I/UI)
Select the waveform to be displayed on the
screen: voltage/current/voltage and current.
