Example (using picture above). Using this example, the home or zero position is above

focus, so raising objectives above sample will decrease motor counts, while lowering

objectives closer to sample will increase counts.

- Objective #1 is selected as the reference objective. When in focus its

motor step count position is 25,000.

- The remaining objectives have focus positions (motor steps) as follows:

o Objective #2 = 34,000.

o Objective #3 = 36,500.

o Objective #4 = 15,400.

o Objective #5 = 20,125.

o Objective #6 = 42,000.

- Each objective offset can be calculated like this:

o Objective #1 offset is zero since it is the reference objective. Any

objective number can be selected as the reference.

o Objective #2 offset: 34,000 – 25,000 = 9000 (or hex h2328).

o Objective #3 offset: 36,500 – 25,000 = 11,500 (h2CEC).

o Objective #4 offset: 15,400 – 25,000 = -9600 (negative, use 2’s

compliment, so hDA80).

o Objective #5 offset: 20,125 – 25,000 = -4875 (hECF5).

o Objective #6 offset: 42,000 – 25,000 = 17,000 (h4268).
