19 Aux Power Supply**
** This pin is connected directly to the positive (+) barrel tip of the power supply input.
When the standard barrel power supply is used, this pin can be used as a power
source (for an external device). If the standard supply is not used (and is therefore
disconnected), power can be supplied to the DVM through pin 19. This is ideal for
high vibration environments where a barrel connector is not secure enough to
maintain a reliable connection.
