[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 chang-
ing 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 wavelength. 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.
