Item Field Description
a Battery status indicator Displays approximate remaining battery life. When
the indicator flashes, the batteries should be changed
immediately.
b REF indicator Press the REF button to toggle through stored reference
values. The reference values for the currently selected
wavelength (CW) or detected WAVE ID wavelengths will
be displayed briefly in the following order:
CW mode: The reference value will be displayed in field e .
Single WAVE ID mode: The reference value will be
displayed in field
e .
Dual WAVE ID mode: The reference values will be
displayed in fields
e and g .
c WAVE ID indicator Displayed when a wavelength has been identified using
the WAVE ID feature.
d Wavelength CW mode: Displays the currently enabled 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 will display HI or LO.
f Wavelength / Tone CW mode: Displays detected tone modulation frequency
in hertz (Hz).
Dual WAVE ID mode: Displays the second WAVE ID
wavelength.
g Power
(Dual WAVE ID mode
only) Displays measured power (dBm or µW), or insertion
loss (dB) at the wavelength displayed in field
f .
If power or loss is too high or too low for accurate
measurement, this field will display HI or LO.
