1Introduction
Congratulations on your purchase of the R2000
Radiometer. This radiometer includes revolutionary
technology that elevates the performance and accuracy
of hand held radiometers to new heights. It joins the
EXFO Life Sciences & Industrial Division 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 Life Sciences &
Industrial Division.
At the heart of the R2000 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
1000 nm. The result is a hand held, robust and versatile
radiometer with accuracy unmatched in the industry.
The R2000 Radiometer provides unique features when
combined with the OmniCure 2000 UV Visible Spot
Curing System.

4Using the R2000 Radiometer
4.1 Turning the R2000 Radiometer ON
The R2000 Radiometer is fitted with an ON switch
located on the front keypad. Press and release the
button. All segments on the display illuminate for 1
second.
Note: If a light guide adapter is installed in the optical
port, the display will flash the diameter of the light guide
adapter for 3 sec.
Note: The R2000 Radiometer will automatically turn
OFF after 1 minute if the unit does not detect any optical
input, RS232 communication, or keypad activity.
Note: The R2000 Radiometer remains in the same
measurement mode that it was in after an occurrence of
an automatic power off.
4.2 Calibration
Should the CAL message appear on the display
immediately following the R2000 Radiometer being
turned ON, it indicates that the unit requires calibration.
The message remains illuminated for 5 seconds.
It is recommended that the R2000 Radiometer be
calibrated every 12 months to ensure valid

Page 11 of 50
measurements. The calibration is traceable to NIST and
a calibration certificate is included at each calibration
cycle.
Calibration is authorized only by a certified EXFO service
center. When calibration is due contact EXFO for a
return authorization number. Refer to Section 9.0.
4.3 Using Light Guide Adapters
Each R2000 Radiometer includes two standard light
guide adapters, 3mm (RED), 5mm (BLUE) and 8mm
(GREEN).
One other size is available: 2mm (GOLD)
Note: If the R2000 Radiometer is on when the adapter
is installed, the display will flash the diameter of the
light guide adapter for 3 sec.
Insert the light guide adapter into the optical input port
to the end of its travel. A click should be heard that
indicates positive insertion of the light guide adapter.
Insert the light guide into the light guide adapter to the
end of its travel. Hand-tighten the thumb screw to
secure the light guide into place. Note: The use of a
tool to tighten the thumbscrew is not recommended.
Over-tightening could cause damage to the light guide.

Page 12 of 50
When the light guide adapter is secured it can remain
attached to the light guide if the light guide is removed.
To confirm which size light guide is inserted press the
ON button simultaneously with the POWER/IRRAD
button. The display will show the diameter of the light
guide in mm (i.e. 5.0).
4.4 Using Non-Standard Size Light Guides
In order to use non-standard size light guides with the
R2000 Radiometer a custom light guide adapter is
required. Contact EXFO Life Sciences & Industrial
Division for further details. Refer to Section 9.
Note: The diameter of the light guide must be entered
in the PC software before the light guide is used with its
custom adapter.
4.5 Connecting to a Light Source
Connect a light guide with corresponding light guide
adapter into the optical input port on the R2000
Radiometer. Turn light source ON. Always turn light
source OFF before removing light delivery from the
R2000 Radiometer. Refer to Section 5 for warnings and
safety precautions.

4.6 Measuring Irradiance
When measuring irradiance, the display will show the
measurement in either mW/cm2 or W/cm2.
If the display is not showing the “ /cm2”, it indicates that
the R2000 Radiometer is in Power mode. Simply press
the POWER/IRRAD keypad button to toggle into
irradiance mode.
The R2000 Radiometer automatically detects the size of
the light guide that is inserted, calculates the irradiance
and displays the measurement.
4.7 Measuring Power
When measuring power, the display will show the
measurement in either mW or W.
If the display is showing “ /cm2”, press the
POWER/IRRAD keypad to toggle into Power mode.
4.8 Measuring in Relative Mode
The Relative mode displays measurements as a
percentage of a reference value. The reference is the
power at the point of entering Relative mode.

Page 14 of 50
Select either Power or Irradiance mode from the keypad.
Adjust the optical source to the desired reference level,
and then press the Relative/Absolute button. The R2000
Radiometer will toggle to Relative mode. All subsequent
measurements will be displayed as a percentage of the
reference.
A reading of “100%” indicates that the current
measurement is the same value as the reference. A
reading of “50%” indicates that the current
measurement is half of the initial reference
measurement. A reading of “200%” indicates that the
current measurement is double of the initial reference.
Inserting a light guide from a different source will
provide a measurement that is relative to the initial
reading as described above.
4.9 Measuring in Absolute Mode
When in Absolute mode, the R2000 Radiometer displays
the reading as power or irradiance, depending on which
mode is selected.
4.10 Connecting External Radiometer Devices
To use the R2000 Radiometer with optional Cure Site
and Cure Ring Radiometers, plug the 6-pin Mini-DIN
style cable attached to the external device(s) into the
Remote Input connector on the side of the R2000

Page 15 of 50
Radiometer. External radiometer devices are available
from EXFO Life Sciences & Industrial Division as custom
ordered items.
Press the EXTERNAL keypad button. The display will
show the EXT icon and a number (starting at 1), that
corresponds to the external radiometer sensor being
detected. This number is shown for a few seconds and
then the display shows the corresponding measurement
of that device.
If multiple devices are connected each press of the
EXTERNAL keypad button will increment to the next
external device before returning back to internal mode.
This is indicated on the display when the EXT icon is no
longer illuminated.
The measurement mode is dependent on the type of
sensor the external device has. For example, the R2000
Radiometer will only measure Irradiance when an
external radiometer device is only able to measure
Irradiance.
The Power mode becomes disabled and the display will
show a ‘Loc’ message if the user tries to toggle into
Power mode.
The same is true for sensors that measure only Power;
the Irradiance mode will not be accessible and the
display with show a ‘Loc’ message.

4.11 Storing Data
The R2000 Radiometer is able to store measurements
based on what is being detected at the time the STORE
button is pressed.
When the STORE button is pressed the display shows
the ‘MEM’ icon and a number (starting at 1), that
corresponds to the number of stored readings. The
number will increment each time STORE is pressed and
the measurement will be stored.
The STORE feature is generally used when the R2000
Radiometer will be connected to a PC via the RS-232
connector. When connected the stored readings are

downloaded into a Data Log as seen on the R2000
Control Panel (via the GUI software provided). The
stored readings can only be viewed by downloading to a
PC. Once a reading has been stored, it can not be
viewed on the R2000 Radiometer display.
4.12 Interfacing with Compatible OmniCure UV
Curing Systems
Refer to the OmniCure Curing System User Guide.
The R2000 Radiometer is equipped with two I/O ports
for communication with compatible OmniCure curing
systems. When connected, the R2000 Radiometer is
able to calibrate the OmniCure SERIES 2000 UV Curing
System and set the irradiance to a specific level.
To interface via the IR
Window:
Point the IR window located on
the R2000 Radiometer directly
at the OmniCure UV Curing
System ensuring that the
OmniCure is turned ON.
Always keep the R2000
Radiometer pointed at the
OmniCure UV Curing System
while performing a function
that is communicating with the
OmniCure.

indicates the IRDA field of
view and operating range for
the R2000/ S2000
combination.
