Voltmeter
Purpose
Output measured voltage as signal

Electrical / Meters
Description
The Voltmeter measures the voltage between its two electrical terminals and provides it as a signal at the output of the component. A positive voltage is measured when the potential at the terminal marked with a "+" is greater than at the unmarked one. The output signal can be made accessible in Simulink with an Output block or by dragging the component into the dialog box of a Probe block.
Note The Voltmeter is ideal, i.e. it has an infinite internal resistance. Hence, if multiple voltmeters are connected in series the voltage across an individual voltmeter is undefined. This produces a run-time error.
Likewise, if switches connected in series are all in open position the voltages across the individual switches are not properly defined. Although this does not produce a run-time error it may lead to unexpected simulation results.
