1Introduction
Congratulations on your purchase of the EXFO
Radiometer. This radiometer includes revolutionary
technology that elevates the performance and accuracy of
hand held radiometers to new heights. It joins the EXFO
family of spot cure and illumination systems, offering the
same high level of innovation, quality and reliability that
customers have come to expect from EXFO.
At the heart of the EXFO Radiometer are two proprietary
systems: a non-imaging optical interface that virtually
eliminates measurement variation caused by radiance and
intensity variations in the light source; and a flat response
optical detector system that responds to energy at all
wavelengths between 250 and 600 nm. The result is a
hand held, robust and versatile radiometer with an
accuracy unmatched in the industry.
Standard and optical accessories include optical adapters
and band pass filters to adapt the EXFO Radiometer to
your specific radiometric application.
The EXFO Radiometer is a high quality product manufac-
tured in accordance to ISO 9001 and certified to CE, UL
and CSA standards.

A) LCD Display:
3'/2 digit display with indicators for low battery, over
range, Peak Hold, % (for Relative mode), Power mode
and Irradiance mode.
Automatic scaling function -
Power: Low range: 10— 990 mW
High range: 1.0— 15.00 W
Irradiance: Low range: 50— 990 mW/cm2
High range: 1.0— 225 W/cm2
B) Bandpass Filters:
User selectable and convenient external installation.
The standard filter is blank. Refer to the accessories in
section 8 for available optional filters.
C) Light Guide Port:
Accepts industry standard light guides and automatically
senses 3, 5 and 8 mm light guide diameters.
(adapters provided for 3 & 5 mm)
D) Relative/Absolute Mode Keypad:
Enables the user to select either Absolute
mode for standard power or irradiance
readings, or Relative mode which displays
readings as a percentage of an
established reference. The display will indicate "%" in
Relative mode. Absolute mode is the initial default.

9
E) Peak Hold Keypad:
Allows the display to indicate the
peak value being measured. The
display will indicate "P" when this
feature is activated.
F) Power/Irradiance Keypad:
Provides the user with the ability to select between
measuring power in "mW" or 'W" or irradiance in
"mW/cm2" or "W/cm2". When in Irradiance mode, the
Radiometer automatically senses 3, 5 or 8 mm light guide
diameters when the appropriate adapter is used.

Irradiance
G) Ergonomically Designed Enclosure:
Compact, hand-held, and portable so it may be used
where it is needed most.

Using the EXFO Radiometer
NOTE: The EXFO Radiometer defaults to the
measurement mode it was in when it last automatically
turned off.
4.1 Turning on the EXFO Radiometer
The hand held Radiometer is not fitted with an ON / OFF
switch. Instead, the Radiometer has been designed with
an auto turn ON and auto turn OFF feature.
The Radiometer will automatically turn on when it detects
an optical signal of 10 mW or greater. When the light
source is removed, the display will remain on for 10
seconds. At that point, the display will flash for 5 seconds
as a warning of impending turn off. The Radiometer will
then turn off.
4.2 Irradiance Measurement:
Insert the light guide into the optical port on the top of the
Radiometer and turn on the light source. The display will
automatically turn on and display the irradiance in either
"mW/cm2" or "W/cm2". If the display indicates power, as
evident by the lack of the "/cm2" icon, press the
Power/Irradiance button once.

11
The display will indicate the irradiance for approximately
10 seconds after the light guide has been removed. The
display will flash for 5 seconds before powering down. The
EXFO Radiometer automatically detects 3, 5 or 8 mm
diameter light guides and calculates the irradiance
accordingly when the appropriate adapter is used.
4.3 Power Measurement:
Insert the light guide into the optical port on the top of the
Radiometer and turn on the light source. The display will
automatically turn on. Power measurements are indicated
by the units of Watts. If the unit icon includes "/cm2",
momentarily press the Power/ Irradiance button.
The display will indicate power in "mW" or 'W" and will
remain active for approximately 10 seconds after the light
guide has been removed. The display will flash for
approximately 5 seconds before powering down.
4.4 Peak Measurement:
To obtain a peak value of a measurement in Irradiance or
Power, follow the steps as outlined in sections 4.2 or 4.3.
Once the Radiometer is in the correct measurement
mode, momentarily press the Peak Hold button. The LCD
display will indicate a "P" in the bottom left hand
corner. The unit will track all subsequent readings and

12
display the peak value. Any subsequent measurements
that are lower than the Peak mode reading will not be
displayed.
4.5 Relative Measurement:
The Relative mode allows the user to display measure-
ments as a percentage of a reference value. Begin by
inserting the light guide into the optical port on the top of
the Radiometer. Select either Power or Irradiance as
described in sections 4.2 or 4.3. Adjust the optical source
to the desired reference level, then press the Relative/
Absolute button. The Radiometer will now be in Relative
mode. All subsequent measurements will be displayed as
apercentage of the reference. A reading of "100%" will
indicate that the current measurement is the same value
as the reference. A reading of "50%" will indicate that the
current measurement is half of the initial reference
measurement.
After removing the light guide, the display will remain on
for 10 seconds. Inserting a light guide from a different
source prior to the display turning off, will provide a
measurement which is relative to the initial reading as
described above.

13
4.6 Using Non-Standard Light Guides:
NOTE: If a light guide with an active area diameter other
than a 3, 5 or 8 mm is to be used in conjunction with this
Radiometer:
1. Select the light guide adapter that is the closest
match to the diameter of the light guide to be used.
2. Configure the Radiometer to measure power.
(irradiance readings will not be accurate)
3. If irradiance values are desired, divide the power
readings by the output area of the light guide being
used.
4. The specifications listed in section 6 cannot be
guaranteed.
