Source sentences:
text: The electronic voltmeter has high input impedance because of which it detects the signals of very weak strength, hence gives the accurate reading.
text: When used for measuring voltage, the input impedance of the multimeter must be very high compared to the impedance of the circuit being measured; otherwise circuit operation may be changed, and the reading will also be inaccurate.
text: Meters with electronic amplifiers (all digital multimeters and some analog meters) have a fixed input impedance that is high enough not to disturb most circuits.
