⚡✅ CORRECT use of the HOOK digital MULTIMETER. Discover the correct use of the clamp-on digital multimeter in residential electrical installations. The digital hook multimeter, also known as a hook multimeter, is an essential measuring instrument for working in residential electrical installations. Its correct use allows the safe and effective measurement of different electrical quantities, such as voltage and current (direct or alternating), electrical resistance and continuity of a circuit.
Multimeters are the essential tool for anyone who needs to measure electrical variables. This instrument is perhaps the best known for its price and practicality.
As its name indicates, a multimeter is a piece of equipment used to make many electrical measurements. This instrument is a combination of several pieces of equipment in just 1, hence its name.
Differentiating a digital multimeter from an analog one is very easy. The analog one has a needle that indicates the selected measurement and the digital one has an LCD display.
Digital multimeters have long replaced analog needle meters due to their ability to measure with better accuracy, reliability, and higher impedance.
Among the equipment that are present in a multimeter we have:
✅ Voltmeter: This instrument allows voltage measurements, there are some alternating current (AC) and direct current (DC).
✅ Ammeter: Used to measure electric current, there are versions for alternating current (AC) and direct current (DC).
✅ Ohmmeter or Ohmmeter: Equipment used to measure electrical resistance, the resulting value is given in Ohms.
✅ Capacimeter: Instrument designed to measure the capacitance value of capacitors or capacitors.
✅ Diode tester: Function that allows you to verify if a diode is functional or if it is defective when measuring
✅ Continuity tester: It allows detecting if a circuit is closed or connected, that is, if there is no interruption. It also helps identify which points make electrical contact.
Depending on the brand and model, the equipment may have other instruments, this is validated in the data sheet.
There are as many multimeters as applications, simplifying, they can be grouped into:
✅ Bench multimeters: These multimeters are the most precise, accurate and with the highest resolution, they are mainly used in laboratories and for automation processes in the industry.
✅ Handheld or portable multimeters: They are the best known, they are small, use batteries and are very practical for maintenance or simple jobs. Hook ammeters are also found here, which are very useful for current measurements and some allow power to be calculated.
A very common parameter in multimeters is the resolution, this indicates the smallest value measured by the instrument on the screen and is represented in digits and counts.
Despite being the basic instrument that anyone related to electronics or electricity uses, it is very common to find doubts about how to use a multimeter? o How does the multimeter work?
So, if you are just getting into the wonderful world of electricity or you are already an expert and want to refresh your knowledge, this video can help you a lot.
