#TEST 1.5 VOLT BATTERY WITH MULTIMETER HOW TO#

So with a very gentle turn of the zeroing screw, about a quarter turn counter-clockwise, the instrument is zeroed and work can begin.

In this condition, it will give an inaccurate result. The green/yellow-striped wire from this pin will be connected to the chassis of a kitchen appliance, for example, and is there to ensure that if a fault occurs and power goes from where it should in the appliance to any part of the appliance connected to the chassis, the earth leakage will be triggered on your electricity distribution board and cut off the power.Ĭan see in the one picture, the needle is not on zero, and if the device is used On this multimeter this is indicated by the 9V BATT 1.5V setting on the dial – see the lower right-hand quadrant on the dialĮarth/Ground ( ): This is the symbol you will find next to the large top pin on an electric plug. BATT: Your multimeter might also have a dedicated setting for testing the amperage of AA, AAA, and 9V batteries.Direct or alternating amperage (A ): When the symbol A is accompanied by a flat bar above three dots, as on this dial, it means that when set to this position, the instrument will measure direct or alternating amperages.Direct Current Amperage (DCA): Similar to DCV, but instead of giving you a voltage reading, it will tell you the amperage.If not, the circuit is not complete so there is a break or disconnect somewhere in it. Continuity ( ): Rather as what happens when resistance is checked, a small amount of current is sent through the circuit to test whether or not it is complete.When it shows, for example, 007, the current can flow easily, but there is more resistance to its flow than when the reading is 004 for example. When it shows 1, there is no path for the current to flow between the two points being checked. Hence, when it shows 000, it is easy for current to flow through. Resistance (Ω): This measures how much resistance there is in the circuit. The lower the number, he easier it is for the current to flow through the material, and vice versa.This setting is used to measure the voltage from alternating current sources, which is the type of electricity that is used in your home and business. Alternating Current Voltage (ACV): Sometimes it will be denoted with a V~.Direct or alternating voltages (V ): When the symbol V is accompanied by a flat bar above three dots, as on this dial, it means that when set to this position, the instrument will measure direct or alternating voltages.This setting is used to measure direct current ( DC) voltage, for example when checking a battery. Direct Current Voltage (DCV): Sometimes it will be denoted with a V▬.Readingįrom the top left of the dial and reading clockwise: The next objective is to ensure that you understand the symbols on the dial.

As you can see from these images, the two digital multimeters have more functions than the analogue version, but essentially, all three have the same basic range of uses.

Note that theĪmount the screw needs to be turned is very little… usually no more than a quarterĭifferent versions of multimeters have different dials according to their brand and their capabilities. Moves left), and you will see the needle will move accordingly. To do that, you simply turn the adjustment screw, usually situated justīelow the dial, clockwise (needle moves right) or counter-clockwise (needle Instrument is zeroed – that the needle with the instrument off, is reading Note that before using an analogue version, you need to ensure that the The analogue version,Īs it uses a needle, means the user sometimes has to estimate by eye exactly User a very precise, easily readable result in numbers. TheĪdvantage of the latter over the former is that the digital readout gives the Plug – that allows the user to take temperatures – the end of the lead has aĮssentially two readout types – analogue, which employs a needle dial, andĭigital, which as the name suggests, displays results on a digital readout. Also note that theĭevice on the right has a third lead – the coiled one above it with the yellow One we used in this feature to show how the device is used. Refer to the ports again in this article. In the picture above, the device on the right has three ports for the probes. The AC voltage function might offer a choice of 10, 50, 250 and 500 volts. Select the various functions, and ranges within those functions. (LED) or analogue (needle) and the selector dial on either type allows you to Multimeters (also known as volt-ohm meters) are used to test voltages (volts),Ĭurrent (amps) and resistance (ohms).

So, let’s take a look at this very useful instrument and how to use it. All, there is NO substitute for reading the instrument’s instructions first,Īnd understanding them, before using any multimeter.
