The positive side of the meter red probe must be connected towards the positive terminal of voltage source refer to Figure 2b. V a b Figure 2 Voltage Measurement Current is measured with an ammeter refer to Figure 3a connected in series with the component whose current is to be determined refer to Figure 3b. Just like the voltmeter, in an ohmmeter, resistance is measured across the load refer to Figure 4b. VOM has more than one scale printed on the face of the meter.

Within each function, a number of ranges are available. Except for the ohm function, the range indicates the maximum amount of a quantity that can be measured on a given range setting. For the ohm function, the range indicates the amount by which the ohm scale is to be multiplied. The ohm scale on the meter is different from most voltage and current scales in three ways.

First, it is reverse- reading. Second, it is nonlinear. Third, the number of minor divisions between the heavy lines and the numbered lines are not the same throughout the scale.

Therefore, the value of a minor division varies across the scale. Analog Multimeter Familiarization 1. Figure 5 shows the basic components of an analog multimeter. Basic Operation of an Analog Multimeter 1. Prepare the analog multimeter for measurement. Turn the zero position adjuster so that the pointer aligns right to the zero position. Select the proper range for the item to be measured by setting the range selector knob accordingly.

Switch on the power supply and adjust to 0 V. Set the multimeter to measure voltage. Start with the highest range when measuring an unknown value. Connect the multimeter directly to the power supply terminals. Make sure the polarity is correct. Observe the effect while very slowly increasing the output voltage control. Adjust the voltage to a value of 3 V.

Remove the meter and connect the bulb across the terminals of the power supply as shown in Figure 6. V Figure 6 8. Now connect the circuit as shown in Figure 7. Set the multimeter to measure current. Once again ensure that polarity is correct before connecting. The meter will now be reading the current flowing in the circuit. If the deflection is too small, switch to smaller range - e. What is the lowest range you may safely use without an over reading? Record the current mA in Table 1.

Increase the voltage in 1 V steps and measure the voltage reading of the power supply. For each value of voltage, measure and record the current.

Be careful in changing the voltage range of the power supply to avoid the damage of the meter movements of the multimeter. Related Papers. By Stephanie Facun. ECA Lab manual. By Ayesha Dawood.

## Breadboard and Analog Multimeter Familiarization OBJECTIVES

A multimeter is a handheld device that combines different electronic testing and measurement tools. A basic multimeter measures resistance, voltage and current. More advanced models can measure capacitance, inductance, and temperature. They may also be able to measure frequency and duty cycle a measurement relating to pulse systems such as fiber optic networks. Basic multimeters typically have a monochrome LCD digital screen capable of displaying numerical figures to two or three decimal places, plus icons to indicate the setting an omega for resistance, for example. Older analogue models may have dial displays with a needle indicating the reading. Sophisticated modern models may feature larger screens that allow them to include an oscilloscope function, displaying waveforms graphically as well as numerical data.

Various Interesting elements like electronic technology, electrical current, resistance, volt, capacitance, and inductance are studied and used in electronics. Radio, Television, LCDs and other electronic gadgets are also included in the field of electronics. Electronics technology is becoming popular even among common masses. Electronics mater is available here to learn the Electronics. In this book, basic principles of electricity have been car rated.

## Parts of the Multitester

A multimeter, also known as a multitester or VOM Volt-Ohm-Milliammeter , is an electronic measuring instrument used to measure various electrical parameters. A typical multimeter can measure voltage, current, and resistance. The best multimeters can also measure other electrical characteristics such as continuity, frequency and capacitance. They also come with built-in non-contact voltage detectors. Multimeters are classified as either digital multimeters or analog multimeters , depending on how the electrical characteristic is being read and displayed.

A typical multimeter may include features such as the ability to measure voltage , current and resistance. Analog instruments are usually based on a microammeter whose pointer moves over a scale calibration for all the different measurements that can be made; digital instruments usually display digits, but may display a bar of a length proportional to the quantity measured. A multimeter can be a hand-held device useful for basic fault finding and field service work or a bench instrument which can measure to a very high degree of accuracy.

### Multimeter Parts & Functions

A multimeter or a multitester , also known as a VOM volt-ohm-milliammeter , is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage , current , and resistance. Analog multimeters use a microammeter with a moving pointer to display readings.

It indicates the measured values on the multimeter. Parts and functions of multi-tester Digital multimeter Analog multimeter 1. Zero ohm adjuster - for analog multi -testers this part sets the indicator of the left scale to zero 2. Range Selector switch knob -this is a switch that is calibrated to select the proper range of the meter 3.

Ну видите, все не так страшно, правда? - Она села в кресло и скрестила ноги.  - И сколько вы заплатите. Вздох облегчения вырвался из груди Беккера. Он сразу же перешел к делу: - Я могу заплатить вам семьсот пятьдесят тысяч песет. Пять тысяч американских долларов.  - Это составляло половину того, что у него было, и раз в десять больше настоящей стоимости кольца.

Беккер попробовал его обойти, но парень ему не позволил. - Я сказал тебе - подними.

Я занесу им, а вы, когда увидите мистера Густафсона, скажете ему, где его паспорт. - Подождите! - закричал Ролдан.  - Не надо впутывать сюда полицию.

Росио сопровождает мистера Густафсона сегодня вечером. Она непременно передаст ему паспорт. Можете оставить свое имя и адрес - наверняка мистер Густафсон захочет вас поблагодарить. - Прекрасная мысль.

В руке его поблескивал пистолет. Беккер, отступая к стене, вновь обрел способность мыслить четко и ясно. Он почувствовал жжение в боку, дотронулся до больного места и посмотрел на руку. Между пальцами и на кольце Танкадо была кровь. У него закружилась голова.

Беккер поблагодарил. Отпил глоток и чуть не поперхнулся. Ничего себе капелька.

Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет. Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме. Он закрыл глаза и постарался сползти на скамье как можно ниже: он единственный в церкви был не в черном.

Где Стратмор. - Коммандер Стратмор погиб. - Справедливость восторжествовала, как в дешевой пьесе. - Успокойтесь, Джабба, - приказал директор, - и доложите ситуацию.

Червь Танкадо не нацелен на наш банк данных.  - Он откашлялся.  - Он нацелен на фильтры безопасности.

The Dial or the Infinity knob - this is the zero collector whenever you calibrate, the beginning as 0 voltages both the AC and DC measurement.
