Loss Test
The loss test loops back the other end of the optical fiber cable being measured to measure the optical
power emitted by the light source of this instrument with the optical power meter of this instrument.
This allows you to check the level of loss that occurs relative to the optical output power value of the
light source.

Saving the Results of Optical Power Measurements for Multi-Fiber
Cables
Skip
When Skip is selected, the corresponding core is not measured. By specifying Skip on cores that do
not need to be measured, you can save time.
Executing a Save Operation
When you execute a save operation, up to three sets of data can be saved temporarily in the save
area of the specified core number.
For details on saving data to files, see section 9.4.
Deleting Data
You can delete data from the save areas for each core number individually or all cores at once.
Starting Core Number
Set the starting core number in the following range.
1 to 9900
Tape Number Type
By setting the tape number type, you can the tape number accordingly.
The core number display will be as follows.
OFF: 1, 2, 3, ...
a-d(4): 1a, 1b, 1c, 1d, 2a, 2b, 2c, 2d, 3a, 3b, 3c, 3d, ...
