Figures 2-3 illustrates the CSM1 display readings described below.
1 Test measurements eld - This eld displays various test measurements as follows:
• Displays measured power [dBm or µW] or insertion loss [dB]. If power or loss is too high
or low for the CSM1 to measure, this eld will display [HI] or [LO].
• Ifthereferencepowerlevelissetforthe currently enabled wavelength, this eld will
display the reference value. To see the reference value, press and release the [Ref] key.
Reference value will be displayed briey (for about 3 seconds), and then Display will
revert to test readings.
2 Wavelength/frequency eld - This eld displays the currently enabled wavelength,
