[ON/OFF] key: This key turns the unit on and off.
[dB/dBm] key: This key controls the following modes:
• Toggles between absolute dBm and relative dB readouts, without
changing the internally stored reference level, when pressed
momentarily.
• Selects a new 0 dB reference level when held down for three
seconds. This is indicated by the "r" annunciator appearing in the
lower right-hand corner of the LCD screen.
Note: The 560XL Series optical power meters incorporate multi-
wavelength reference storage capability. This enables a 0 dB reference
value to be stored in non-volatile memory for each calibrated wave-
length. The reference values will be stored in memory until a new 0 dB
reference is established for a wavelength by holding down the
[dB/dBm] button as described above.
