NOTE
Take care not to move CURSOR A control during
measurements to reduce error. If CURSOR A control is
moved, reposition cursor until TI displays A = recorded position
again. Doing this will reestablish same optical power reference
level as before and calibration may continue with no additional error.
(19) Press HOR CONT pushbutton for maximum horizontal contraction.
(20) Press DISPLAY FROM pushbutton to select B.
(21) Adjust CURSOR B control to place cursor B in approximate middle of flat
portion on top of FOCUS generated pulse (fig. 12). Record B= distance indicated on TI
display on TD-260C (850 nm) Reference Cursor Position Data Sheet (appendix A).
Figure 12. Example of cursor B placement in center flat portion on FOCUS generated pulse (TD-260C).
NOTE
Take care not to move CURSOR B control during
measurements to reduce error. If CURSOR B control is
moved, reposition cursor B so TI displays B = recorded
reference cursor position again. This will reestablish same
measured power level on FOCUS generated pulse as before
and calibration may continue with no additional error.
(22) Perform (a) and (b) below:
