The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
0.0001
The Vernier caliper is an extremely precise measuring instrument Error is almost impossible The error that we must always look out for is the zero error and parralex error.
on the very top of the burette. Should start from zero to 100mL on the burette
How much error is allowed in a digital vernier
If you are doing your job properly, you DO!
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
If a vernier caliper has zero reading of 0.025 cm and the caliper reads 5.565 cm what should be the correct reading? 5.565 - 0.025 = 5.54 so caliper reads 5.54 cm If the zero reading on the vernier calipers is -0.025 cm with the reading still 5.565cm, it is 5.565 - (-0.025) = 5.565 + 0.025 = 5.59 cm
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 .
It is a defect in a measuring device (Vernier Callipers & Screw Gauge) & zero error is caused by an incorrect position of the zero point.
It is the measuring instrument it is invented by verniers its error is very small
The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.
A vernier caliper.
The scale doesn't start at zero, so you need to compromise or you get a systematic error.
