Explanation
This feature is available on models with the /SPM or /HPM option.
Models with the /PPM option do not have the Auto Loss Test feature, so combine these models with a
light source and the optical power meter feature to perform the loss test. For details, see sections 7.1
and 7.3.
Zero Set
Perform a zero-set whenever necessary, such as after you have turned on the power or when the
ambient temperature changes.
Performing zero set adjusts the internal deviation of the optical power measurement section and
enables you to obtain more accurate absolute optical power values. Perform zero set on the optical
power meter.
Optical Power Adjustment
Adjust the optical power of the light source as necessary. When you execute optical power adjustment,
the Instrument automatically identifies the optical power level and adjusts itself accordingly. Perform
optical power adjustment on the light source side.
• Press the Execute soft key to execute the optical power adjustment. When adjustment ends
normally, the Instrument returns to the previous screen. While adjusting, the word “Execute” on the
menu changes to “Abort.” All soft keys other than Abort will be invalid.
• When you press the Abort soft key, the optical power adjustment will be aborted. The word “Abort”
On the menu returns to “Execute.” The adjustment value returns to the previous value before the
execution.
• Connect an optical fiber that is no longer than a few meters. Make sure that the fiber is free from
dirt, scratches, bends, and other potential causes of optical degradation.
• The default adjustment value is set to the factory default value.
Executing an Auto Loss Test
Configure the optical power meter side and the light source side. Connect the optical fiber or optical
circuit to be tested to the optical power measurement port on the optical power meter side and the light
source port on the light source side. Then execute the loss test. The optical power of the light passing
through the optical fiber or optical circuit to be tested is measured on the optical power meter side.
