There is no negative zero or positive zero, zero is just zero so you can take it off.
For example: 3-2-0= just 3-2
Zero error is necessary for measuring instruments for measuring accurate results because it helps to check that the instrument which we are using is whether correct or wrong
The correct term isA zero pair is when one pairs a positive counter and a negative counter.HOPE THAT HELPED!!!**Calypso214
we can find the zero error by closing the jaw of screw guage if the zero of main scale(MS) is concide with the zero of circular scale (CS) there is no zero error and if they are not concide there is a zero error in screw guage .
When I type any number divided by zero into my calculator, it flashes, "ERROR, ERROR," but I say it's possible. "It's not possible to divide by zero," my math teacher says, but who cares about her? Here's my data after graphing it out: If any positive number is divided by zero, it's infinity, if it's negative, it's negative infinity, and zero divided by zero is one. NO NO, you cannot divide by zero, really. See my discussion post.
Positive and negative whole numbers and zero are integers. Zero is neither negative or positive.
if the zero of vernier scale lies on the right side of the zero of the main scale , then error is known as a positive error .
the correction which is made to get correct measurement after zero error
Positive zero error means, instead showing zero it shows some value more than zero. Hence positive. Suppose if it shows some reading say 0.03 units. then while correcting we have to subtract the above from the observed reading. So correction is adding negative error.
There can't be a negative zero. zero is neither negative nor positive.
When a positive number is subtracted from zero the result is a negative number.
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.

zerro error in a spring balance affects the accuracy in the weight. To find zero error in spring balance, you have to first find the least count of the spring balance and then suspend it freely, if the outcome is +1, the zero error is +1 and if it is -1 ,the zero error is -1.
Zero error in an Essae weighing machine refers to the condition where the scale does not read zero when there is no weight on the platform. This error can occur due to mechanical misalignment, calibration issues, or wear and tear of the components. It is important to identify and correct zero error to ensure accurate measurements, typically by adjusting the zero balance or recalibrating the machine before use. Regular maintenance and calibration help minimize zero error and improve weighing accuracy.

When the anvil and spindle end are brought in contact, the edge of the circular scale should be at the zero of the sleeve (linear scale) and the zero of the circular scale should be opposite to the datum line of the sleeve. If the zero is not coinciding with the datum line, there will be a positive or negative zero error as shown in figure below.

It is a defect in a measuring device (Vernier Callipers & Screw Gauge) & zero error is caused by an incorrect position of the zero point.
