When the jaws are closed, the vernier zero mark coincides with the zero mark on its fixed main scale. Before taking any reading it is good practice to close the jaws or faces of the instrument to make sure that the reading is zero. If it is not, then note the reading. This reading is called “zero error”. biologic treatment for crohn\u0027s disease

WebNov 14, 2024 · The margin of uncertainty in a single reading is taken to be half the smallest increment on the measuring scale. This is because any reading should be rounded to the increments given on the scale. For example, if you measure the length of a pencil as 15cm to the nearest cm, the true length could be anywhere between 14.5 and 15.5cm.
