What is the scale of a voltmeter?
voltmeter, instrument that measures voltages of either direct or alternating electric current on a scale usually graduated in volts, millivolts (0.001 volt), or kilovolts (1,000 volts).
What is scale in analog multimeter?
Scale and Range Many analog multimeters can measure both AC and DC voltages and can measure dozens of voltage ranges. A multimeter scale with mirrorWhen viewing the scale above, a user may conclude that the meter is able to measure three different voltage ranges: 0-10V, 0-50V, and 0-250V.
What does 200K mean on a multimeter?
200,000 ohms
You have to choose a range of values on a manual meter. 200K is about right for a tongue measurement. The numbers beside the dial are the maximums, so 200K means no more than 200,000 ohms and 20K means no more than 20,000 ohms.

What is full scale current?
Full scale deflection has its history in analogue meters where the moving needle could “deflect” and that deflection was proportional to what it measured i.e. Current, voltage or power. FSD is the maximum deflection the needle moved and, this represents the “full scale”.
How do we read voltage from the scale?
Look carefully at the voltage scales, either DC or AC. There should be several rows of numbers beneath the scale. Check which range you have selected on the dial (for example, 10V), and look for a corresponding label next to one of these rows. This is the row you should read the result from.
How do you read a 20K multimeter?
Note that the numbers beside the dial are maximums, so 200K means “no more than 200,000 ohms” while 20K means “no more than 20,000 ohms.” See the close-ups of the manual meters in Figure 6.
What is 20M on a multimeter?
The highest current you can measure is 20mA, if you set it to 20m. If you are on 20mA and it says 0.25, that’s probably because you’re measuring 0.25mA. You don’t have to worry about picking a range when you set the auto-ranging multimeter to current mode.
How do you find the right scale on an analog multimeter?
Find the right scale on an analog multimeter. Analog multimeters have a needle behind a glass window, which moves to indicate the result. Typically, there are three arcs printed behind the needle. These are three different scales, each of which is used for a different purpose: The Ω scale is for reading resistance.
How do you measure DC voltage with a multimeter?
Analog Multimeter, Measuring DC Voltage. Basics to Measuring DC Voltage. 1. The Red Meter lead/Probe is Positive 2. The Black Meter lead/Probe is Negative 3. There are three meter scales you are working with. Each range on the DC display is used for two positions of the selector switch.
What is the scale of a circuit?
SCALE – is a series of marking used for reading the value of quantity. Scale can have different types of scale, for voltage and current readings the scales have mostly linear which mean equal division for resistance . TEST PROBE- Positive (red) negative (black) is use to connect the circuit to the electrical components being tested.
How do you use a multimeter to measure resistance?
Disconnect the power before measuring resistance. Turn off the power switch or remove the batteries powering the circuit in order to get an accurate resistance reading. The multimeter sends out a current to measure the resistance, and if additional current is already flowing, this will disrupt the result.
