Chapter8 Measurement Functions
This chapter describes the characteristics and operations of the basic metering
function of IT7900P series source.
IT7900P series source has rich functions of basic metering of electric energy
and can accurately measure the parameters such as Vrms, Irms, Ipeak, Idc, CF,
PF.
8.1 Meter Mode
Press on the front panel to enter the metering interface. Different
modes display different interfaces, but the displayed measurement parameters
are the same. Take AC single-phase mode as an example, the measurement
interface is shown in the figure below.
