( 3 ) When satisfied that autoreflector will r e main ~n alinement without fur ther ad justment, request OIC to verify auto collrmatron and horizontal scale sett ing to FA, notify supervisor that MONITOR switch can be pressed

NOTE When MONITOR switch is pressed (MONITOR lndlcator lrghts and


VLT OP

LAY PLATF indicator goes out), the 60- second optical mon~toring period is initiated. During this time, the autoreflector is lighted for 55 seconds and then flashes for 5 seconds.

NOTE. Angular drsplacement (drift) of ST-120 may be estimated by using the lateral distance between the double vertical reticle lines as a reference. The angle represented by this distance is approximately 0 .2 mil.

( 4 ) When directed by supervisor, press MONITOR switch, and mon~tor ST-120 to determine if its drift rate is within 0.1 mil In 6 0 seconds (vertex of autoreflector remained within double vertical reticle lines); ~f ST-120 drift rate is out of tolerance, notify supervisor.

NOTE. After monitoring period ends, approx~mately 9 0 seconds elapse before LAY PLATF indicator starts flashing, periodically observe autoreflector to determine that d r ~ f t does not exceed 0 2 m ~ l outside of either double vertical reticle line during this t~me. ( I f RESET switch has been pressed, or durlng horizontal lay recycle, LAY PLATF indl cator starts flashing without delay at end of optlcal monitoring period.)

NOTE If directed by supervisor, again monitor ST 1 2 0 to determine if its d r i f t rate is within 0 1 mi l in 6 0 seconds If d r i f t rate is out of tolerance, notify supervisor, press RESET switch, and proceed to sequence 5 ( 1 ) above, if clrift is within tolerance, notify super visor that COMPLETE sw~tch can b e pressed

( 2 ) When directed by supervisor to press COMPLETE switch, center autoreflector in reticle, if necessary, by setting and holding PLATF CONTROL switch, then press COMPLETE switch

( 3 ) Notify supervisor that COMPLETE switch has been pressed.
