CHECK WIELITE caulilys al not The specified value (difference between Staff reading 1 and Staff reading 2) should not exceed 3 mm. Repeat the test (changing roles - you are now Learner 2 and your Trainer/Assessor will be Learner 1). Record the readings in Record Table 1. For this next part, two Learners are required to do the test. Learner 1 set up the level midpoint and take the staff reading for point 1 and 2. Learner 2 holds the staff. Record the readings to three decimals in Record Table 2. Then Learner 1 moves to the Learner 2 and takes the staff. Learner 2 moves now the level opposite to position A or B at 4 metre distance behind the point and takes the staff reading 1 and 2. Record the readings to three decimals in Record Table 2. Then calculate the difference between the readings and record the figure in the Table. Check whether it's within the specified limit. The specified limit is 3 millimetres. If the collimation error is greater than 3 mm, the test must be repeated. Make a sketch of the set out points and label the points. Include your readings and your partners.
