What do ammeter and voltmeter measure? These are devices designed to measure both voltage (voltage) and amperage (current). They are also known as multimeters or volt-ammeters. When measuring voltage, the device measures the potential difference between two points. The volt-ammeter is connected in parallel to the circuit when measuring voltage. During current measurement (ampere measurement), it is used to measure the current flowing through the circuit. The volt-ammeter is connected in series with the circuit when measuring current.
Selectable scale: Many volt-ammeters have selectable scales for different voltage and current ranges.
Digital and analog display options: Analog volt-ammeters have a display panel with a pointer, while digital volt-ammeters display results with an LCD or LED display.
Advanced features: Professional volt-ammeters have additional features such as automatic scale selection, voltage drop detection and temperature measurement.
Analog and digital voltmeters and ammeters are a versatile measurement tool in the electrical and electronics field. When used correctly, it provides valuable information about circuits. However, it is essential to understand the features and limitations of the instrument and to be careful.
