Trigger1: After clicking Run, wait for the Trigger1 signal to be received to 
start executing sampling. 
Trigger2: After clicking Run, wait for the Trigger2 signal to be received to 
start executing sampling. 
Capture-Vac: The voltage signal sampling after compared. When this mode 
is selected, additional parameters need to be set. 
⚫  Trigger delay: Set the sample data delay time. Set a positive value to record 
data after the capture event occurs. A negative value means that data before 
the capture event occurs is recorded. 
⚫  Compare: Select the object of comparison, either Vac/Rms or Vac/Peak 
⚫  Up Limit: AC voltage upper limit value, grid voltage greater than the upper 
limit value will start sampling. 
⚫  Down Limit: AC voltage lower limit value, grid voltage less than the lower 
limit value will start sampling. 
⚫  Display mode: Auto/Normal 
5.16 Voltage Signals Simulation 
In AC mode or AC+DC mode, users can import TDMS waveform curve files for 
simulation, and set parameters such as repetition times and waveform offset for 
imported waveform. 
By default, the open waveform is only for real-time simulation. If you remove the 
USB disk, the waveform disappears. Users can also permanently save the open 
waveform to the power supply memory. 
Directly  click  Simulation  in  the  Menu  to  enter  the  voltage  signal  Simulation 
interface, as shown below: 
 
 
Start mode: can be selected as immediate execution or trigger execution. 
Interval  time:  The  interval  between  waveform  repeats.This  parameter  is 
displayed only when start mode is selected for Imme. 
Repeat: Number of repeated execution of waveform 
Coefficient: Waveform amplification Coefficient 
DC: DC offset
