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.

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.
What is the difference between Error detection and error correction?
In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.
When an error of 1 percent is made in the length of a square error is?
The error in its area is then 2 percent....
What is the 5 types of errors that do not affect the balancing of trial balance?
1 error of omission 2 error of compensation 3 error of original entry 4 error of principle 5 error of commission
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?" ;)
Do i have to start all over again if i forgot to zero a scale in an experiment?
It is best practice to zero the scale before starting any experiment to ensure accuracy. If you forget to zero the scale, it's important to correct the error by zeroing the scale and recalibrating before proceeding further to ensure accurate results. Starting over may be necessary depending on the requirements of the experiment and the extent of the error.
