Description

[Picture]

The Ammeter measures the current through the component and provides it as a continuous signal at the output. The direction of a positive current is indicated by the small arrow at one of the electrical terminals. The output signal can be made accessible in Simulink with a Continuous Output block or by dragging the component into the dialog box of a Probe block.


Note  The Ammeter is ideal, i.e. it has zero internal resistance. Hence, if multiple ammeters are connected in parallel the current through an individual ammeter is undefined. This produces a run-time error.

Likewise, if switches connected in parallel are all in closed position the current through the individual switches is not properly defined. Although this does not produce a run-time error it may lead to unexpected simulation results.


Parameters and Dialog Box

Width
The width of the component. This affects both the width of the electrical ports and the width of the output signal. The default is 1.

Probe Signals

Measured current
The measured current in amperes (A).
