Assume that the function range switch is on the 20k position and the multimeter displays 1 when the test leads are across an unknown resistor What would most likely cause the meter to display 1?
the function range switch is not set on a high enough scale
How do you measure voltage?
Voltage can be measured using the difference between the potentiel between two ends of wire or by using a volt-meter. You can easily measure volt by volt or multimeter but remember voltage always measure across the components but in parallel
How does the meter have to connect to the battery in order to provide an indication?
The meter ( as refered to a conventional moving coil analog pointer type ) basically operates on a Direct Current ( DC ) passing in its coils. Hence the meter inherently has a polarity of operation i.e the positive & negative inputs of the meter must be connected appropriately with the corresponding positive & negative potentials in the circuit being measured , so that the meter deflection is in the correct direction of the measuring scale ( typically clockwise movement ) Bsis Voltage & current measurement scales are linear , while resistance ohmic measurement scales are generally non linear. Incorrect polarity of connection will result in the meter deflecting in the opposite direction & usually will not damage the meter unless an inappropriate measuring range was selected. Whenever the magnitude of measured voltage or current is not known approximately beforehand, the best precaution is to use the highest range on the meter & stepping down the range if the deflection is too low for a good reading.This will prevent damage to the meter due to overload deflection which generally will damgage the delicate moving parts of the meter, which results in a total writeoff. For measuring voltages , the meter configuration as a voltmeter is used, where a series voltage dropping high value resistor appropriate to the range of voltage being measured is incorporated into the meter itself. The voltmeter is always connected across the points where the measurement is required. Hence no alteration of circuit is required for this measurement. For measuirng current, a low value resistor across the coils of the meter is incorporated appropriate to the range value of currents being measured, as a shunt to divert currents larger than what the basic meter can handle. It is necessary to break the circuit at a convinient point where the measurement is required and the meter inserted into the circuit. Hence an alteration of circuit is required for this measurement. When a meter is configured to measure resistance , a low voltage battery source with appropriate circuitry is incorporated into the meter itself to read the resistance value directly in ohms. Modern digital meters generally have bipolar measurement capabilities, in which the polarity of measurement is indicated. Here only the moving coil meter is replaced by a analog to digital convertor chip which directly displays the value on the digital readout. Otherwise the same measurement principles apply.
What could be the tendencies for the voltmeter if the voltages to be measured exceed the range?
You'd potentially damage the meter. Whether you do or not is immaterial; if the meter cannot measure the range of voltages you are expecting, it will not give accurate readings over that voltage range, thus you should not use it. Buy a different meter that will measure over that voltage range, or use a voltage divider circuit to get a lower voltage at a certain ratio of what is actually in the circuit (this may be difficult to do, or very simple depending on the circuit tested - the key is you do not want to load the circuit with the voltage divider network).
How can you read current on a digital multimeter?
First select the correct measurement type. Current is measured in series and most meters have separate inputs for that. Resistance should be measured with the component out of the circuit. Volts in parallel. Be very careful. Best is to be shown how. ANSWER: A meter any meter cannot measure current directly but rather it measure the voltage drop to translate into amperes.
If a digital meter is place in the 4000 mA range what will the display read if 2.685 Amps are measured?
2685
What unit are virus's measured in?
Viruses are measured in nanometers (nm) a billionth of a meter. Viruses range inside from 20 to 40 mm Viruses are measured in nanometers (nm) a billionth of a meter. Viruses range inside from 20 to 40 mm
The meters function range switch is set to read DC voltage in the 20 Volt range The meter displays a 1 in the most significant digit position What does this indicate?
the meter measured a voltage of 1 v at the point under test.
What is the actual measured resistance of the circuit if the Vom is set to the R x 100 range and the meter face reads 22.5?
2,250Ω
How do you test 220 volts using a volt meter?
Make sure that the test meter is on the correct voltage scale. Place one lead on one of the conductors to be tested and the other lead on the other voltage source conductor. The reading you obtain will be the voltage potential between the two conductors.
On the 10a range the meter shows 2.56 does this mean two fifty six thousandth's amps?
No. The "10A" range means "please don't pass more than 10A through the meter while it's switched to this range".The display reads the current directly, i.e. 2.56 Amps.
What are two ways to measure flexibility?
flexibility is measured by the range of motion and the range of motion and the range of movements is measured by using a goniometer.....
Assume that the function range switch is on the 20k position and the multimeter displays 1 when the test leads are across an unknown resistor What would most likely cause the meter to display 1?
the function range switch is not set on a high enough scale
What is the difference between operating range and display range?
Display range for a calculator may be 10 digits. That is all the screen will display. The operating range may be 12 digits, 2 extra digits are kept in memory so that the next calculation will have less rounding error.
