| 08:19 | Now, I will show a basic experiment using the device and interface. |
| 08:25 | In this experiment, we will measure and compare the voltages of external and internal sources. |
| 08:33 | To show the experiment, we require a battery as external source of voltage. Voltage of the battery is “3V”. |
| 08:44 | For this experiment, Ground (GND) terminal and A1 terminal are connected to the battery. |
| 08:50 | On the interface, click on A1 to show the voltage across A1 terminal. The displayed voltage is “+3.15V”. |
| 09:00 | On reversing the connection, the voltage is “-3.14V”. |
| 09:06 | In the place of the battery, we can use PVS as internal source of voltage. For this experiment, A1 is connected to PVS. |
| 09:17 | On the right side of the interface, Set PVS value= 3V and press Enter. The displayed voltage of PVS is 3.001V. |
| 09:31 | On the top left corner, click on A1. The displayed voltage of A1 is “3.008V”. |
