|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
