Step 5: Set the OA 5000 attenuation to 0 dB, and the DISABLE button
off (unlit).
Step 6: The power meter reading is the insertion loss of the OA 5000.
Check that the power meter reading is ---2.0 dB or higher (more posi-
tive).
NOTE
During the remaining steps, do not disturb the connections and
fibers.
Step 7: Set the dB reference (Disp-->Ref) at the power meter. The
power meter reading should be 0.00 dB within ±0.01 dB.
Step 8: Set the OA 5000 to each of the settings in the table below, and
check that the power meter reads within the listed accuracy limits. At
30 dB, note the reading.
Step 9: Set the OA 5000 to 0 dB. Check that the power meter reads
0.00 dB within the repeatability specification (±0.05 dB).
Step 10: Set the OA 5000 to 30 dB. Check that the power meter reads
the same as in step 8, within the repeatability specification (±0.05 dB).
Step 11: If the readings in steps 9 and 10 do n ot meet the repeatability
specifications, check the connections, and repeat steps 7 to 10.
