HSet the WAVELENGTH(nm)display to read “1300”.

HPush the WAVELENGTH button once more; check that the button is

no longer backlitand that the MODE button is backlit. (After exiting

the wavelength mode, the instrument may require a secondor two

to recalculate calibrationfor the new wavelength; the ATT ADJ light

next to the ATTENUATION(dB) display will brief ly be backlit to indi-

cate this.)

Step 1: Push the ADDR(SET)button once.

HThe button should becomeback lit,the ATTENUATION display

should read “Addr”,and the WAVELENGTH display should show a

number from 0to 30 or the word “OFF”.

Step 2: While in thismode, the coarse and fine knobs should increment

or decrement the displayedaddress value by 1; adjust the value, using

the knobs, to the address desired.

HCheck that when 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 exited.

Step 1: Enter the Wavelength set modefor 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 WavelengthSet mode by pushing the WAVELE NGTH

button again; the instrumentw illrequire a second to prepare the new

calibration tables (as indicated by the ATT AD J briefly lighting up).

Step 4: Adjust the OA 5000 such that the display modeis showing

attenuation in dB with the ATTindicator lit and the ---REF indicator not lit.

Step 5: Using the knobs, increase the level ofattenuation (turn the

coarse knob clockwise); keep increasingthe level until the value reach-

es a maximum level and nolonger increases. This value should exceed

60.00 dB.
