The single-phase power factor measuring instrument is similar to the power meter. It also has
four terminal buttons, including two current terminal buttons and two voltage
terminal buttons. . . When there is more than one current and voltage limit,
there will be more terminal buttons. Pay attention to the selection when wiring. One of the current and voltage
terminals is also marked with a special mark,
that is, the generator terminal. Their wiring method is exactly
the same as that of the power meter.
  Single- phase power factor meters must be used within the specified frequency range
