Suppose say you have plastic rule new one. There you will be having zero marking. When you have to measure the length of a rod then you would keep zero marking at one end of the rod and the marking where the other extreme of the rod is taken to be length of the rod. say it is at 4 cm. So 4cm is the length.
And suppose the ruler is an old one whose edge got damaged. Now you don't have zero marking so visible there. So you have keep the end of the rod at say 1 cm marking. Now the error that we commit is known as zero error. Here the error is positive. ie +1 cm.
So as the other end of the rod is at 5cm marking then the correct length is got by applying zero correction. As zero error is +1 cm, then zero correction would be -1 cm
So the correct length 5-1 ie 4 cm.
Same way in case of vernier, if zero of vernier is at left side of zero of main scale, then the zero error is negative.
If zero of vernier is right side of zero of main scale then error is +ve as we have seen in the earlier old ruler case.
Same way in case of screw gauge as the head scale zero is above pitch line then error is negative and as head scale zero is below pitch line then zero error is positive.

Why must to zeroing before start using spetrophotometer?
Zeroing a spectrophotometer before use is essential to establish a baseline measurement. This process accounts for any absorbance or transmittance caused by the solvent or the cuvette itself, ensuring that the readings reflect only the sample's properties. By zeroing, you eliminate systematic errors, allowing for accurate and reliable data when measuring the concentration of analytes in your samples.
What are the common sources of error occurring in using vernier calipers?
Common sources of error when using vernier calipers include parallax error, which occurs when the scale is not viewed straight on, leading to misreading the measurement. Inaccurate zeroing of the caliper can also introduce errors, as any misalignment affects all subsequent measurements. Additionally, improper placement of the caliper on the object being measured, such as not ensuring the jaws are fully closed or not applying consistent pressure, can lead to inaccuracies. Lastly, wear and tear on the caliper itself may affect precision over time.
What are possible sources of errors in the vernier caliper measurement?
Possible sources of errors in vernier caliper measurements include parallax error, which occurs when the observer's eye is not aligned with the measurement scale, leading to incorrect readings. Additionally, improper zeroing of the caliper can result in systematic errors, while wear and tear on the jaws can affect accuracy. Environmental factors, such as temperature variations, may also cause expansion or contraction of the caliper materials, impacting measurement precision. Lastly, human error in reading the scale or misaligning the object being measured can lead to inaccuracies.
What is the difference between systematic error and accidental error?
Systematic error is a constant or known:effects of the error are cumulativeerror is always positive or negativeAccidental error is a unavoidable error: effects of the error is compensationerror is equally like to be positive or negative
What is the difference between a bias and a random error?
Bias is systematic error. Random error is not.
Why do you zero a triple balance before using it?
Zeroing a triple beam balance ensures that the readings are accurate by eliminating any measurement error caused by the starting point of the balance. It also helps to maintain the balance's sensitivity and precision. Without zeroing, the weights calculated may be incorrect leading to inaccurate results.
What is an example of convergent?
Deductively zeroing in on a multiple choice answer.
Decreasing or zeroing out subscriptions will automatically reduce the on hand quantities?
false

What is the purpose of the zeroing resistor in an ohmmeter and does it always accomplish its intended purpose?
A: There is no zeroing resistor the leads resistance are the zeroing resistor. there is however a pot where the zero can be accomplished by adjusting the current flow out of the meter to measure the voltage to determine the resistance. that pot is an adjustment to compensate for an old internal battery drift. If not changed periodically it may become a useless meter because zero cannot be achieved
Describe what it means to tare or zero an electronic balance what purpose does this function serve?
In order to verify and ensure accuracy of instrumentation zeroing is done. By zeroing the scale operators can establish a baseline of an empty scale registering '0' mass.
What is it called if you use the knob under the pan to line up the triple beam balance pointer with zero?
It is called "zeroing" the balance. This process ensures that the pointer is accurately aligned with the zero mark, which is the starting point for measurements on the balance.
Why is it important to zero a spring scale?
Zeroing a spring scale ensures that it reads accurately by accounting for any variations or offsets in its baseline measurement. By zeroing the scale before each use, you can obtain precise weight measurements and minimize errors in your readings.
When is it appropriate to press the tare button on an electronic balance?
after zeroing the balance and placing an empty weighing paper on it
My Hard drive is clicking and i have a primary hard disk error message?
The "Clicking" sound that a hard drive makes is NEVER a good sound. What you are hearing is the drive re-zeroing (the heads are returning to the home position) because it is having read errors.The fact that you're getting a "primary hard disk error" indicates that the drive is most likely beyond help.Sorry to tell you this, but it's time for a new hard drive.See the question: "Why is it important to make backups?" ;)
