Line Description
55 to 57 Unit1 waits for a trigger sent to the Ext Trig In terminal, and starts measurement by receiving
a trigger sent by Unit2.
59 to 61 The lines can be replaced with 55 to 57.
Delete ’ at the top of the lines 59 to 61, and delete lines 55 to 57, then run the program.
Unit1 will start measurement when a trigger is received via the Ext Trig In terminal.
62 to 64 The lines can be replaced with 55 to 57.
Delete ’ at the top of the lines 59 to 64, and delete lines 55 to 57, and 61, then run the program.
Unit1 will start measurement when a trigger is received via the Ext Trig In terminal.
66 to 71 Waits for the operation complete and checks if an error occurred. If an error is detected, forces
0 V and goes to Check_err.
73 to 77 Reads measurement data and stores it into the data array.
79 to 81 Applies 0 V from all channels and transfers the data stored in the data variable to the
save_data subprogram. And the subprogram will save the data into a CSV file specified by the
fname variable and displays the data on a message box.
