Type
Description
AMMETER
A device that reads and displays the current flow in a circuit.
COMBINED
A device that reads and displays the value of multiple properties of a system at a point, or displays the difference in the value of a property between two points.
FREQUENCYMETER
A device that reads and displays the electrical frequency of an alternating current circuit.
PHASEANGLEMETER
A device that reads and displays the phase angle of a phase in a polyphase electrical circuit.
POWERFACTORMETER
A device that reads and displays the power factor of an electrical circuit.
PRESSUREGAUGE
A device that reads and displays a pressure value at a point or the pressure difference between two points.
THERMOMETER
A device that reads and displays a temperature value at a point.
VOLTMETER
A device that measures and displays the voltage in a circuit.
VOLTMETER_PEAK
A device that reads and displays the peak voltage in an electrical circuit.
VOLTMETER_RMS
