The power measured by the power meter is displayed in large characters in the units
selected in the configuration menu, along with:
• The mode of transmission of the signal measured
• The wavelength of the signal measured
• The reference level expressed in dB
• The level of Attenuation Compensation
Table of results
For each fiber being tested, the power meter displays a table of nine results corre -
sponding to the different possible wavelengths. The first four results are displayed on
the screen. To scroll through the other results, use the direction key. The table shows
the power measured in dBm, the relative power in dB, and the reference level in dBm
(if units = dB), together with the mode.
NOTE
Most of the configuration files are available in disk/config .
