If staff is not vertical, the reading will be too great. If staff is normal to the line of sight the value will be minimum or accurate. It will not be maximum. The intercept of staff increases when it is tilted away from normal and decreases or gets minimum when moved towards normal.

When telescope pointing down, then tell me what will happen if we move a vertical staff?

Staff intercept is the difference in reading between top and bottom cross hairs. If the staff is tilted forward or backward from normal, the staff intercept will increase. It is minimum when staff is truly vertical.

What is the intercept of staff?

SUMON PAUL said:   5 years ago
Reading will increase in both cases, if tilted away or towards. Because it's minimum when staff held normal. So you can't go below the minimum. So answer D is also correct but B is more logical.

Thanks @Aman and @Jeevitha.

Staff intercept: is the difference between the reading measured at top cross hair and bottom cross hair of telescope.

According to definition, only answer B is correct.
