What is a multimeter?
A multimeter is a device for measuring electrical parameters such as (voltage, current, resistance, diode test, capacitor meter, etc.). Multimeters in the world are made in two forms and are available as hands or so-called analog. And digital
An analog or multimeter , which has been used since ancient times, consists of a calibrated screen, the display hand can be moved to the left and right, and the settings selector.
To measure the parameters in a hand-held multimeter, you must first adjust the selector screw on the parameter values required for measurement, and then use the available interface cables or probes on the desired part and measure the parameter value.
The potentiometer on the multimeter is used to set to zero. Usually analog or hand-held multimeters for high-precision measurements in electrical repairs, TV repairs, laboratories, and so on. Is used.
Digital Multimeters These multimeters are similar in appearance to analog multimeters, except that the existing seven-segment digital display, which displays numbers digitally, has been replaced by an existing dial and hand.
Digital multimeters, like hand-held multimeters, have a selector screw that can be adjusted to measure specific parameters.
For accurate measurement, first place the selector on the desired parameter and then measure the desired parameter.
In practice, other names are used for this application device, such as these names. (Avometer, ohmmeter, ammeter, clamp ammeter, that all these devices work like a normal multimeter and except for clamp ammeter, which in addition to measuring the mentioned parameters has the ability to measure the current parameter inductively is .
Flow measurement with a multimeter
As we know, to measure the current, the ammeter must be placed in series in the circuit, but this is not possible in working circuits, because first the circuit must be cut off and then the ammeter in the circuit.
That’s why a device calledClamp amp meterOr pliers ammeter, a hook ammeter that has the ability to measure current without interruption. In this way, it is enough to select one of the wires in the circuit that is considered and place the clamp of the ammeter around it and read the value displayed on the device.
This practical device in the electricity industry has made work very easy.
