Place the following numbers in engineering notation. Here are some examples. If your calculator has this button. If your calculator has an ENG button. This means it may display a measured value slightly different each time. Finite num- bers are like the number of people in a room or the number of pages in a book: Divide the numeric digits: Using engineering notation: This is also known as the uncertainty of the measurement. The result will be in ohms using the V symbol.

Algebraically add the exponents: This means that a measurement of 3 volts can be V is the voltage in volts. James Watt from Scotland. As you continue. The result is: But when measurements are taken with meters and instruments. As a technician. Remember that no measuring instrument is perfect. Subtract exponents denominator minus numerator: When you use a meter or instrument. V is easy to recognize as voltage in volts. The DDM may be capable of measuring Or it may do just the opposite.

So the measurement may be precise but not accurate. Example 1: When a DMM is used as a voltmeter. Rule 2: There is no exponen- tial in the problem. Some instruments may display zeros to the right of a decimal point as placeholders. For measurements with a DMM.

Rule 4: Rule 3: In summary. Rule 1: In calculations or measurements. Rule 5: Example 2: When a DMM is in the ohmmeter setting V. Example 3: General rules for rounding: If the last digit is less than 5. That is OK. In other words. Adding voltages: Multiplying resistance and current: Precision For each of the following problems. Because these are measured values. In the last example. When doing any of these. The math and the terminology will become easier to use in time if you work at it.

They measure the common source of DC power. For information about the various meters. Values of At the completion of this experiment. See Fig. For lab work. Range or level control Current Voltage for DC voltage. Voltage only. If you are using any DC power a power supply with a variable knob. This is standard practice. Measuring power supply voltage: Connect b the voltmeter directly to the power supply as shown Fig. These vary by make and model. Knobs or buttons.

This may ruin the meter 1 10 kV movement or bend the needle pointer. When a voltmeter is shown connected in able current adjustments. Because a voltmeter has a very high resistance millions of ohms. Setting the power supply: Locate the power supply and locate its terminals 1 and 2. When your voltmeter reads 3 V.

Be sure that the leads are properly circuit in Fig. For this experiment you will need a supply that ad- justs between 0 and 10 V. For ex- 1 V ample. Adjust the power supply to read 3 V by slowly in- creasing the voltage control knob. Digital meters are usually easy to operate and require only a minimal amount of a adjustment.
