Item	Field	Description
A	Battery status indicator	Displays the approximate remaining battery life. Three bars indicate the charge
		level. When the battery indicator flashes, the batteries should be changed
		immediately.
B	REF indicator	Press the Ref/Set button to toggle through stored reference values. The reference
		values for the currently selected wavelengths are briefly displayed in the following
		order:
		CW mode: The reference value is displayed in field E.
		Single WAVE ID mode: The reference value is displayed in field E.
		Dual WAVE ID mode: The reference values are displayed in fields E and G.
C	WAVE ID indicator	Lights when a wavelength has been identified using the WAVE ID feature with a
		compatible light source.
D	Wavelength	CW mode: Displays the currently selected wavelength.
		Single WAVE ID mode: Displays the detected WAVE ID wavelength.
		Dual WAVE ID mode: Displays the first detected WAVE ID wavelength.
E	Power	Displays measured power (dBm or μW), or insertion loss (dB) at the wavelength
		displayed in field D.
		If power or loss is too high or too low for accurate measurement, this field
		displays HI or LO.
F	Tone / Wavelength	CW mode: Displays detected tone modulation frequency.
		Dual WAVE ID mode: Displays the second detected WAVE ID wavelength.
G	Power	Displays measured power (dBm or μW), or insertion loss (dB) at the wavelength
	(Dual WAVE ID mode	displayed in field F.
	only)	If power or loss is too high or too low for accurate measurement, this field
		displays HI or LO.
