The screen at right shows information when power readings are
being taken. We will refer to this screen throughout this manual
as Immediate Mode.
POWER READING - shows the amount of optical power being
received by the photodetector based upon the type of power
units currently being displayed. The display may also show
UNDER when there is no measurable optical power or OVER
when there is too much optical power to measure
POWER UNITS - shows the power units which are currently
being displayed
dBm - optical power in decibels relative to a milliwatt of optical
energy
dB - optical power in decibels relative to a previously set optical reference, also known as optical loss
uW - optical power in watts; either microwatts (uW) or milliwatts (mW)
TONE DETECTION - shows ‘Hz’ if a modulated signal is being detected by the meter
TEMPERATURE - shows current temperature in degrees (selectable Fahrenheit or Celcius)
BATTERY LIFE - shows the amount of remaining battery life; will flash BAT when battery is low
LIGHT SOURCE WAVELENGTH (only appears if optional light source is installed) - displays the current
light source wavelength output
LINK NAME - shows the name of the currently loaded fiber link (if shown)
FIBER RUN - shows the current fiber information (if shown)
FBR: - user-configurable descriptive fiber name
123 - auto-incrementing fiber number (from 1 to 999)
FUNCTION OPTIONS MENU - functions corresponding to the function keys on the keypad; the options
on this menu will change according to the current function
POWER METER WAVELENGTH - shows the currently selected wavelength (see the specifications in
the appendix at the end of this manual for a list of wavelengths); will also alternate between wavelength
and ‘AUTO’ when set to automatic wavelength detection mode
