What are the main scale and vernier scale readings?
Vernier scale consists of main scale and vernier scale. The first line or the zeroth line coinciding with the main scale reading is the main scale reading. The vernier line except zeroth line coinciding with any line on main scale is the main scale reading.
What tool to use when measuring the weight of a mouse?
To measure the weight of a mouse, you can use a digital or analog weighing scale. Place the mouse gently on the scale and wait for the reading to stabilize. Make sure the scale is sensitive enough to accurately measure the relatively light weight of a mouse.
How to take a main scale reading and vernier scale reading?
To take a main scale reading, identify the whole number on the main scale that is to the left of the zero mark on the vernier scale. Then, identify the vernier scale division that aligns closely with a division on the main scale. Add the main scale reading and the vernier scale reading together to get the final measurement.
How do you read micrometers?
Difficult to explain without diagrams, but the micrometer relies on an accurate screw which advances the caliper a precise amount with each revolution. So you turn the screw until the object is lightly held, then read the axial scale and add on for the number of screw turns above the nearest scale reading. The most accurate type also have a vernier scale for very small distances. I suggest you look at Wikipedia 'Micrometer' which has a thorough explanation with diagrams.
How would you weigh a feather?
A feather can be weighed using a sensitive scale such as a jewelry scale or a scientific balance. Place the feather on the scale and ensure it is settled before taking the reading. Feathers are very light, so a precise scale is necessary for accurate measurement.
What are the differences between a mounted digital kitchen scale and a standard analog kitchen scale?
The main difference between these scales it that the digital will give a more accurate and easier to read reading than figuring it out with the lines between the numbers the analog scale. However, the digital scale requires and battery and the analog does not.
Does an electric food scale give an accurate reading?
Assuming the scale is new, and has been calibrated properly, it should give an accurate reading. To be sure, compare weights on an electric, and traditional scale.
What is the use of the measurement range in a multimeter?
With today's auto-ranging meters, you might well ask why. Today meters do that for you, and you might see it happening on some of them. In older meters, analog types in particular, you had to start with a higher range to be sure you didn't peg the meter measuring say, 220 volts when on the 10 volt scale. Lots of meters where toasted this way, their needles bent, or fuses blown by overcurrent. On higher ranges, the meter would deflect slightly, indicating there was voltage there, but not enough to get a accurate reading. So you scale down until hopefully you get a reading somewhere in mid scale, where the most accurate reading can be made. So the use was to protect the meter from damage, and provide the most accurate reading possible from an analog meter.
How do you read vernier calipers?
We need two readings. One is Main scale reading and the other is vernier scale reading. Main scale reading will be read on the main scale. We need an indicator to read it. Right? The marking ie zero of the vernier is that indicator. So the reading on the main scale which has been just crossed by zero of the vernier is taken as Main scale reading. Now to get VSR, we need vernier scale coincidence. How do we get this? Any one of the divisions of the vernier will be found coincided with some divisions marked on the main scale. We don't worry about that main scale division but we concentrate only on the vernier scale division. This is VSC This VSC is to be multiplied by least count. So VSC x LC gives the VSR Now MSR + VSR gives the accurate reading.
What type of meter shows reading on a non-linear scale?
-- analog ohm-meter -- analog power meter -- analog audio level meter -- slide-rule multiplication/division scales -- slide-rule tangent/cotangent scales -- analog tuning dial on an AM radio
At which end of the ohms scale are resistance measurement more reliable the zero end or the infinity end?
On an analog ohmmeter, measurements are more precise and more accurate at the zero end of the scale.
Differentiate between main scale reading and vernier scale reading?
main scale is the least accurate reading on the device. the vernier scale uses an offset of divions that only allows one "line" or division to line up with the scale below. This scale is more accurate than the main scale. for example, the main scale may produce an accuracy of 0.125 of and inch plus or minus 0.125 of an inch, whereas the vernier would produce an accuracy of 0.025 of and inch. therefore if two divivions of the main scale and one division of the vernier scale were combined it would prodice and reading of (0.125+0.125+0.025 = 0.275) inches.
Why cannot a meter scale be used instead of a vernier calliper?
It can, but the vernier is capable of a more accurate reading.
What is the difference between an error as a percentage of full scale or an error as a percentage of reading?
Error as a percentage of full scale is established by multiplying the error percentage by the full scale flow. The less you flow through the device the less accurate the reading will be. For that reason, you don't want to get a larger device than you need. Devices with error expressed as a percentage of full scale are most accurate when flowing at full scale.Error expressed as a percentage of reading expresses error as a percentage of what the device is actually flowing. Simply, if a instrument's accuracy is rated to +/-1% of reading an instrument will be accurate to +/-1% of whatever the instrument is flowing. At 100SLPM the instrument will be accurate to within +/-1SLPM, and at 10SLPM of flow the unit will be accurate to within +/-.1SLPM.
What are the main scale and vernier scale readings?
Vernier scale consists of main scale and vernier scale. The first line or the zeroth line coinciding with the main scale reading is the main scale reading. The vernier line except zeroth line coinciding with any line on main scale is the main scale reading.
How do you check accuracy of bathroom scale?
There are many bathroom scales nowadays that are claiming to be accurate. Some of these bathroom scales have gone digital. One way to check that your bathroom scale is giving you accurate results is to calibrate it so that you will know that your bathroom scale is definitely accurate. Try weighing something that you know the exact weight of. For example, weigh 10kilos of sugar or flour on the bathroom scale and check if it gives the exact result of 10kilos. If it does, then it is definitely accurate. But it if it gives you far off result, then the bathroom scale isn't worth it.
How does an aquarium thermometer work?
An aquarium thermometer typically works by measuring the temperature of the water through a sensor inside the tank. The sensor detects the temperature and displays it on a digital screen or analog scale. Some thermometers may have a probe that is submerged in the water to provide an accurate reading.
