H Set the WAVELENGTH(nm) display to read “1300”.
H Push the WAVELENGTH button once more; check that the button is
no longer backlit and that the MODE button is backlit. (After exiting
the wavelength mode, the instrument may require a second or two
to recalculate calibration for the new wavelength; the ATT ADJ light
next to the ATTENUATION(dB) display will briefly be backlit to indi-
cate this.)
Step 1: Push the ADDR(SET) button once.
H The button should become backlit, the ATTENUATION display
should read “Addr”, and the WAVELENGTH display should show a
number from 0 to 30 or the word “OFF”.
Step 2: While in this mode, the coarse and fine knobs should increment
or decrement the displayed address value by 1; adjust the value, using
the knobs, to the address desired.
H Check that w hen the value is adjusted above “30” that the word
“OFF” appears.
Step 3: Push the ADDR(SET) button once again while the desired
address is being displayed; the display mode should return to whatever
state the instrument was in before pushing the ADDR(SET) button.
NOTE
The address of the instrument is not actually updated until the
ADDR (SET) mode is ex ited.
Step 1: Enter the Wavelength set mode for the OA 5000 by pushing the
WAVELENGTH button so that the display reads “SEt”.
Step 2: Using the knobs, adjust the wavelength to read 1350 nm.
Step 3: Exit the Wavelength Set mode by pushing the WAVELENGTH
button again; the instrument will require a second to prepare the new
calibration tables (as indicated by the ATT ADJ briefly lighting up).
Step 4: Adjust the OA 5000 such that the display mode is showing
attenuation in dB with the ATT indicator lit and the --- REF indicator not lit.
Step 5: Using the knobs, increase the level of attenuation (turn the
coarse knob clockwise); keep increasing the level until the value reach-
es a maximum level and no longer increases. This value should exceed
60.00 dB.
