1 Introduction
The main purpose of this LED Light Meter System is to provide accurate absolute
power/irradiance measurements for various lens options and wavelengths of an
Excelitas LX series UV LED spot curing system or any other commercially available
UV LED spot curing system.
This product will complement the Excelitas LX series and will also cater to
commercially available LED UV spot curing systems.
We recommend that you read this manual to discover all its features, and how to use
them

2.2 Safety Precautions
DIN Multi Pin Connection Port For External Sensors
(for use only with sensors supplied by Excelitas Technologies)
For using the Sensor, connect cable to this port.
WARNING
When using LED Heads do not stare directly at the LED Aperture(s). This may be
harmful, resulting in eye injury. Always use the protective eyewear provided with this
device. Additionally, protect any exposed skin with appropriate clothing or shielding
as required.
WARNING
To prevent accidental exposure to hazardous optical/ UV radiation, always ensure
that the LED Heads are properly secured in a mounting fixture. Hand-held use of the
LED Heads is not recommended and may expose the user to dangerous optical
radiation.
Caution, Hot Surface
Due to elevated operating temperatures; avoid contact of the LED Head(s) when
energized The LED Heads are designed to be mounted in a suitable fixture prior to
use. Clamp type heat sink assemblies are provided with each LED Head to provide
user safety and optimum thermal management. Prior to handling of the UV LED
Head(s), allow a cool down for a period of approximately 5 minutes after system
power has been removed.
Warning
The LED Light Meter is supplied with two lithium batteries. Lithium batteries present
a potential fire, explosion or severe burn hazard. DO NOT attempt to re-charge,
disassemble, incinerate, short circuit or expose battery to temperatures above 100°
C or expose contents to water.
WARNING!
Used batteries are not to be discarded. Return to the nearest authorized Excelitas
Technologies service center for disposal/ recycling.
Lithium batteries must have terminals taped with non-conductive material prior to
returning for disposal/re-cycling to prevent short-circuiting. External packaging
material must provide adequate protection to contents.

The lithium battery supplied in this system DOES NOT contain: mercury, lead,
manganese or cadmium. Substitution of any other type of battery is not recommended
and may void warranty.
Caution
The detection window operational life can be significantly shortened if it is handled
incorrectly. Do not touch the window surface. Skin oils and scratches can cause the
window to fail prematurely.
Cleaning:
Clean the exterior of the Light Meter with a slightly dampened cloth and simple water/
detergent solution only. Refer to section 9.2 for detailed cleaning instructions.

4.1 Power ON/OFF
4.1.1 Press ‘ON/OFF’button to switch on the unit. The power on sequence will flash full
screen information for 5 seconds and then display current wavelength.
4.1.2 The Meter will auto power off after 5 minutes (system will remember the last mode
and wavelength on power up).
4.1.3 Hold ‘ON/OFF’ for 4 seconds to turn power off.
4.2 Peak Hold
4.2.1 ‘Peak Hold’button (Irradiance or Power Mode): in either modes the meter latches
on to the peak value and refreshes the display when the value is higher than the
current displayed value.
4.2.2 Upon pressing the button once, the meter will activate the ‘Peak Hold’mode and
the system will display “peak hold”(displays “peak’ over top of ‘hold’) to indicate the
peak hold mode. Pressing ‘Peak Hold’ again the meter will revert back to the
normal default mode which displays the current value.

5 LED Light Sensor:
5.1.1 Removable threaded aperture will allow a choice of Power or Irradiance to be
measured.
5.1.2 To remove the aperture, twist and rotate the aperture in a counter-clock wise
direction. (do not use mechanical tooling). Refer to Figure 5.
5.1.3 To install the aperture, engage threads and hand tighten the aperture in a clock
wise direction until a positive force is felt. (do not over tighten or use mechanical
tooling). Refer to Figure 5.
Note: Ensure the supplied aperture is used with the sensor, exchanging other
apertures invalidates the irradiance calibration.

6 Calibration
6.1.1 It is recommended that the LED Light Meter system be calibrated every 12
months to ensure valid measurements. The calibration is traceable to NRC and a
calibration certificate is included at each calibration cycle.
6.1.2 Irradiance calibration is only valid with the correct aperture supplied, Exchanging
other apertures invalidates the calibration.
6.1.3 Calibration is authorized only by a certified Excelitas service center. When
calibration is due contact Excelitas for a return authorization number. Refer to
Section 0.

7.1.6 If utilizing an XY alignment tool/fixture adjust XY positions over the detection
window/aperture to achieve maximum Power/Irradiance level. Secure LED Head
into desired position.
7.1.7 If not using an alignment tool/fixture manually move LED Head over the detection
window until maximum Power/Irradiance level is achieved and secure LED Head
into desired position.
XY Alignment Tool:
Provisions for an alignment tool/fixture is recommended to
eliminate the alignment challenges which may be encountered to
capture accurate peak power or irradiance measurement.
Note; Do not use mechanical device to remove or install Aperture.
Carefully install by hand until snug. Ensure the Aperture and the
detector optical window are clean before each use.

9 Care and Maintenance
9.1 General
9.1.1 The LED Light Sensor can be stored in its original individual packaging, or in the
plastic case with the LED Light Meter –there is a special cut-out in the foam
insert for this purpose.
9.1.2 Do not touch the LED Light Sensor’s optical window with fingers or any abrasive
object. Large measurement errors may result from be generated through
scratches, digs and other coating damage on the Sensor optical window surface.
Refrain from touching the optical surface with any foreign object which could
scratch the optical window.
9.2 Cleaning
9.2.1 Cleaning of the Sensor is not generally required. However, if any visible
contamination or finger prints appear in the optical window, the contaminants may
cause inaccurate measurement. If required, gently clean the Sensor optical
window and the aluminum housing with reagent grade alcohol and soft cotton
swab, a minimum amount alcohol is preferred to avoid alcohol contamination in
the detector.
9.2.2 Large measurement errors may result from be generated through scratches, digs
and other coating damage on the detector optical window surface. Refrain from
touching the optical surface with any foreign object which could scratch the optical
window.
Warning:
Seals are not 100% water tight. Use of excessive liquid will flood and
damage the electronics.

9.3 Lithium Batteries
9.3.1 The lithium batteries (qty.2) in the LED Light Meter are expected to last for 1 year
under normal operating conditions. Do not remove the batteries from the Meter
until the low battery code ‘BAT’ appears on the LCD screen.
9.3.2 The batteries are accessible through a cover located on the underside of the LED
Meter. When replacing the batteries ensure that both batteries are replaced at
the same time.
9.3.3 Use the batteries supplied by Excelitas Technologies, do not substitute with
another brand. The batteries in the Meter are not standard AA batteries. The
voltage of the standard AA batteries will not supply enough power to operate the
LED Light Meter.
9.3.4 To replace the Excelitas Technologies supplied lithium batteries:
Remove the protective rubber boot.
Remove qty.2 Philips Screws.
Open battery cover.
Remove and discard old batteries
Insert new batteries (refer to the + / - placement decal inside the battery cavity).
