“Over” is displayed if the power is more than the maximum level of
the measurement range.
When the reference value in [7] is set to
None, pass/fail status
determined according to the threshold value in [8] is indicated.
If it is determined as fail according to the threshold, the
background color will get red.
[5] Range indicator
If the power level of the light currently being measured becomes
high, the display will extend to the right.
[6] Average
Displays the number of times that the current test data is averaged
before the Power reading is refreshed. The higher the number of
averages, the more stable the Power reading.
Touching the field allows you to change the value.
[7] Reference
Displays the power level that is basis of loss calculation.
Touching the field allows you to change the value.
[8] Threshold
Displays the value to determine pass/fail status of power or loss.
Threshold must be set for each wavelength.
● Threshold for power when the reference is set to
None
● Threshold for loss when the reference is set to
None
Touching the field allows you to change the value.
[9] Loss
Displays the power loss. When the reference value is set to
None,
“−−−−−” is displayed.
The optical power loss is obtained as follows:
Loss = Reference – power measurement (dB)
When the reference value in [7] is not set to
None, pass/fail status
determined according to the threshold value in [8] is indicated. If it
