5.15 Voltage Sampling
The IT7800 series instruments can be used as data sampling devices to collect
voltage variation signals from other instrument. With this function, users can
realize the acquisition of the actual grid voltage change state of the DUT, and
then use the import function to reproduce the grid state.
Connecting method
When the voltage signal is sampling, the wiring method is the same as the test
line connection method when outputting. For single-phase, connect the two
terminals A and N, and for three-phase, connect the four terminals ABCN. For
details, refer to section 2.5 Connecting the Test Lines, and take the sampling
DUT supply voltage signal as an example, the wiring diagram is shown below.
Operation method
Click Menu > Volt sample and enter to Voltage signals sampling interface, the
display is shown below.
