a. Locate the delay knob on front of oscillator
CB630C and note present reading.
b. Set delay to 550 µs.
c. Perform Daily Startup procedure (see page 2-1).
5) On RB601 adjust crystal position for maximum 532 nm
energy.
a. While still at reduced power, place a power meter
after port #2 and align 532 nm into center of detec-
tor head.
b. Using the RB601, tweak SHG for highest energy.
c. Slowly bring system up to full power by setting
the CB630C delay to the value noted in step 4a.
d. Again tweak SHG for highest energy.
6) Harmonic installation is now complete and normal
