For measuring electrical quantities, the terminal of the meter that is connected is the Input terminal.

• The input terminal is where the electrical quantity (such as voltage or current) enters the meter for measurement. In various types of meters, including energy meters and multimeters, the input terminal is crucial for obtaining accurate readings of the electrical parameters being measured.
• The output terminal, on the other hand, is typically used to send the measured data to a display or another device, while the pointer mechanism refers to the part of an analog meter that indicates the measurement but does not directly relate to where connections are made for measurement.
