How to Use Analog Multimeter: Common But Crucial Fact

11 rows · Dec 12,  · How to use Analog Multimeter; 1. Check your multimeter before using it; . Mar 24,  · Connect the test leads to your analog multimeter Use the following setups for measuring different quantities: Use an AA battery to measure voltage, DC voltage, and current. Use an AC socket to measure AV voltage and current.

Electricity is an invisible, silent and odorless physical phenomenon. To find out if a circuit is live, if an electric current is flowing, for troubleshooting, electricians frequently use a multimeter. But how to use it? This guide aims to use analog multimeter correctly. Power failures are commonplace in everyday life, a blown fuse, a light that goes out, a battery that may be dead. Without using a multimeter it is difficult to see clearly.

But how do you adjust it, plug it in, and interpret the measurement? Easy with these few explanations. But beware, an absolute rule in electricity: priority to safety. Before use, it is important to check the multimeter and the insulating gloves to ensure your safety.

Note that, if how to use analog multimeter fuse is blown, it is important to replace it with a strictly identical fuse in order to prevent the device from exploding in the event of incorrect handling. For insulating gloves, make sure they are not punctured. To do this, they must be inflated like a balloon and check that air does not escape.

Measuring a voltage is an essential operation to know if an electrical panel is live, to troubleshoot a circuit, to measure the value of the voltage … so many essential indications for the electrician.

Place a point of the bead on each of the two points of the voltage to be measured. The intensity of an electric current represents the quantity of electrons which circulate in the electric wire. Some multimeters are equipped with an amp aerometric measuring clamp which greatly facilitates this operation. Switch off the circuit by tripping the general circuit breaker located next to the electricity meter for example. If the device is equipped with a current clamp, it is sufficient to insert the wire in the clamp and how to use analog multimeter read the displayed value.

For an electric cable, you must insert the clamp on a wire of the cable and not on the cable. This function is very useful how to use analog multimeter troubleshooting to test a fuse, a lamp, a switch or measure the value of the resistance of an oven in particular.

The measurement of resistance or electrical continuity is always how to become a dance competition judge with the power off, otherwise the multimeter could be damaged. To measure the resistance of an element, it is essential to disconnect at least one wire, otherwise the measurement will be inaccurate. Place a point of the bead on each of the two points of the resistance to be measured.

An analog multimeter is equipped with a needle dial. If its reading is less easy than a digital multimeter, it is nevertheless more suitable in certain cases, in particular for observing variations in value. Its setting and connection are identical to the digital multimeter, only its reading is different. Before using it, you must adjust the needle to 0 by moving it using the screw located on the dial or on the back of the device.

To have an accurate reading you have payday 2 how to get halloween masks see a single hand in the mirror of the dial ; move the gaze laterally to achieve this and, only afterwards, read the value indicated by the needle. Save my name, email, and website in this browser for the next time I comment.

The analog multimeter is a handy and beneficial instrument utilized to calculate electrical parameters and magnitudes. If you have no idea how to use analog multimeter, here we give you a complete guide. Analog multimeter is a small device with an interface with a pointer that calculates a . The multimeter position and the obstacles to be measured must be parallel. • Look at the size result on the display. If it turns out the resistance is too small, turn the selector switch to the other X to get a more accurate result. That’s a review of how to use analog multimeter and read how to read the results. Hopefully it can be helpful. Aug 16,  · Multimeters are exactly what how they sound- electronic measuring instruments with the ability to measure several different things, all in one unit.

You may be wondering why you need to know how to use an analog multimeter in a wildly digital age. Well, the reasons are plenty.

As a modern electrician, you never know when and where the need arises for you to read an analog display — whether it is on a multimeter or another measuring tool.

Analog multimeters have a moving needle that stops on a number printed on the background behind the moving needle. The number that the needle stops on indicates the volts, ohms or amps the meter is measuring depending on how the control knob is set. Analog multimeters are cheaper than digital multimeters but not as robust or simple to use. Some technicians prefer analog multimeters because the needle movement can show you some things that are not obvious with digital multimeters.

Analog multimeters or test meters are test instruments based around the use of a moving coil meter. This analog form of display uses the deflection of an indicator needle to indicate the level of the measurement being made. The basic meter used in an analog meter is a moving coil meter, and this deflects from its rest position increasingly as the measurement quantity increases. These meters were a feature of many laboratory views photographed before the s and s when digital technology supplant analog techniques.

The analog test meter typically contained a single meter and movement, and series and parallel resistors were used to provide the correct ranges. Typically a large rotary switch in the centre of the front panel under the meter was used to select the required range. There are sometimes several different connections used for the probes. There are usually common and standard measurement probe connections.

The normal one is often labelled Amps, Volts, Ohms or similar, indicating its usual measurements. Also, for some measurements with either very high or low current, a different probe connection may be used.

These other probe connections may be designated 10Amps for a ten amp range, etc. Hold that big picture in your mind, then add these key concepts about both electricity and VOMs:. Before we can jump into the steps, the workings of an analog meter scale must be fully clear to us. This is important because we have been so acclimatized that it can become slightly confusing to read the analog scale with our digital tools.

Take a look at the image shown below. In the image, at the bottom left is where your test leads will be connected. It is similar to how you connect the leads in a DMM. The ports in the bottom right are for advanced options. The optional polarity switch comes in handy when you want to reverse the polarity of your measurement.

The switch in the middle is how you select the quantity to be measured and the desired range. Some multimeters have different switches for range and quantity selection.

Some also have a separate dial for zeroing out the meter, which we will cover later in this guide. The top line in black is the ohmic scale, where you measure the resistance from left to right.

Based on the range selected, you will have to multiply the scale reading with the range currently selected. For example, if the pointer is steady at 5 and your range is 1k, your reading is 5k ohms. Below the ohmic scale are the voltage and current scales. The black line adjacent to the ohmic scale is where you measure DC voltage and current. The red line is always for AC measurements. Please note that current and voltage measurements are read from right to left. A voltmeter will only have two scales for AC and DC voltage measurement, whereas an ammeter or a galvanometer will only have one scale for AC and DC amps measurement.

As noted earlier, the key to accurate analog measurement is range selection and multiplication. Everything else is similar to what and how you do use your DMM. You will also have to do simple multiplication to get the final measurement. For example, if your DC volt range is V, and the pointer is between 50 and , then the voltage is around 75 volts depending upon the exact point.

You have the essential guide on using an analog multimeter to measure voltage, current, and resistance. The basic principle is the same as DMM, but you need to put in more efforts here.
