User's Manual

Introduction

The EIT

LED-R™ Series of instruments is a new family of instruments with optics designed for the measurement of UV LEDs. The instruments build on EIT’s

32+ years of UV measurement experience and previously released products that have bene used to measure broadband UV sources. The first products

released are LEDCureRadiometers in Profiling and Non-Profiling (Standard) versions.

The EIT

LED-R™ Series of instruments feature a Total Measured Optics Response.

The LEDCure builds and improves on the success of previous EIT radiometers, instruments which are widely used for accurate, repeatable UV measurement of

broadband sources throughout the global UV industry. The LEDCure features selectable sample rates, reference modes and UV irradiance profile graphs. The

new instrument is designed specifically to measure UV output from industrial UV LED light sources. As with other EIT products, the instrument is simple to use

with easy push-button operation.

The LEDCureis a self-contained, electro-optic radiometer that measures and displays the total UV energy and UV irradiance of a UV LED curing system. The

LEDCurecombines compact size and robust design to withstand the extremes of UV LED curing environments while providing accurate measurements.

The carefully engineered optical sensing systems only measure LED wavelengths that are relevant to the UV process in the LED band specified. The output of

the sensing system is converted to digital form and displayed on an easy-to-read OLED display.

The LEDCureprovides measurement from a choice of one of the available EIT wavelength bands designated LXXX, where XXX is the center wavelength of the

source to be measured in nanometers (e.g. the LEDCureModel L395 measures 395nm center wavelength LED sources).

EIT Instrument Markets LEDCureis manufactured in the USA. Patent Pending.

The Process Values

The two process values read by the LEDCureare total energy and peak irradiance. The irradiance reading is instantaneous and is the highest amount of UV

energy that the unit senses during an exposure run. The irradiance value is energy at one instant in time during the exposure run. The radiometers measure

and display irradiance in Watts or milliWatts per square centimeter (W/cm

, mW/cm

Total energy density (sometimes referred to as “dose”) is a factor of irradiance over time. The instruments derive this value from the irradiance values during

the exposure run and the length of time of the run. Total energy is measured in Joules or milliJoules per square centimeter (J/cm

mJ/cm

Reaching the energy and irradiance values specified by your process is necessary for achieving a complete UV cure.

Ultraviolet Radiation

Although this product is not a source of UV light, it is used in a

UV environment. Refer to the UV source's documentation for

recommended protective measures against UV radiation present

in the UV environment.

Identifying Instrument Type

The instrument band, dynamic range and whether the instrument is Profiler enabled can be found in two locations on the instrument

Operating the Radiometer

Turning “ON” the Radiometer: Press and Hold the ON/OFF button until the display illuminates. The display will briefly display the Radiometer Model Name,

Serial Number, Software Version, Calibration Date, Range, and Wavelength Bands installed. The display will then enter the default mode and display the data

from the last run before the unit was turned off.

Turning “OFF” the Radiometer: Press and Hold the ON/OFF button. A tone will sound. When tone stops, release the button. The unit turns off.

Entering the “RUN” MODE: A short press of the RUN button clears the memory and puts the unit in the “RUN” mode. The display shows “RUNNING” after

shortly displaying the internal temperature of the unit. Confirm that the unit displays “RUNNING” before initiating a reading.

Place the radiometer on the belt or object with the optic window looking toward the UV source. The display and buttons will be facing away from the UV source.

When the radiometer exits the curing chamber, the display will still be flashing “RUNNING”.

CAUTION: Exposing the display to high UV radiation will damage the display.

Exiting the “RUN” MODE: A short press of the STOP button (Soft button display bar indicates STOP next to the ON/OFF button) will exit the RUN mode and

will return to the same default mode prior to making the exposure run, but will display the new value.

Setup & Default Modes

To enter the Setup Mode, use the soft button to the left of the display, Press and hold for 0.5 second, then release. The Setup screen will display the

current settings. Default modes will appear preceded with an *asterisk. The setup screen below shows the four user selectable variables.

Diagnostics & Error Messages

The LEDCurecontinuously performs internal self-diagnostic tests. If the unit detects an internal problem, it will display one or more of the following error

codes in the upper left corner on the display. Error codes are two alphanumeric characters preceded by an *. If two errors are experienced at the same time,

both error codes will flash alternately on the screen every 0.5 seconds. Certain error codes may indicate problems that require returning the unit to the factory

for service.

Low Battery Indicator

*LB – Low Battery

If this happens during an exposure run, the reading is still valid. The low battery indicator is designed to illuminate early enough so that your data remains valid.

Under severe low battery conditions, the unit does not operate. Therefore, confirm that the unit flashes “RUNNING” before initiating a reading.

Over-Temperature State

*OT – Over Temperature

If the internal temperature of the LEDCurePlus exceeds 65

C during an exposure run, the unit will emit a steady beeping tone after the run. However, the

data it has collected is accurate and can be read by pressing the Select button. When doing this, the beeping tone stops and you can scroll through the data

readings. In addition, if the internal temperature of the unit exceeds 75

C, the unit beeps once then displays the internal temperature continuously. The unit

will not operate until the internal temperature drops below 75

C. The maximum internal temperature is 80°C. If the internal temperature exceeds 80°C, the

warranty is voided. CAUTION: If you press the Reset button to initiate the RUN mode before the unit cools to 75

C, all data from the previous exposure run is

cleared from memory. The unit beeps and again continuously displays the temperature.

Over Range State

*OR – Over Range

The over range error message will be displayed if the peak irradiance value is too large for the instrument to measure. Note that a unit’s full scale range will be

marginally higher than the normal range. Readings that exceed the nominal range and do not result in an *OR error are valid.

Other Error Codes

For all other error codes, please call EIT for disposition.

Replacing the Batteries

The LEDCureshould be turned OFF.

1. Loosen the screw on the battery door and remove the door.

2. Remove the old batteries.

3. Install two new AAA size alkaline cells, observing polarity. Note: Both cells are installed in the same direction. The proper direction is indicated on the

PCB and on the housing inside the battery compartment. The unit is designed so it will not operate with reversed cells.

4. Replace the door and the screw.

Appendix

Display Cleaning Instructions

Use of a clean cotton swab, lint free wipe, or EIT prepackaged optical wipes are recommended for cleaning the display

window. Use of Isopropyl Alcohol is acceptable.

WARNING – DO NOT USE ACETONE TO CLEAN THE DATA DISPLAY SCREEN. IT MAY DAMAGE THE DISPLAY.

Optics Cleaning Instructions

EIT Instrument Markets cannot have full knowledge of contaminants present in all applications and as a result cannot test for their effects. Therefore, we cannot

assume responsibility for damage to customer instruments, which results from following these directions once the warranty period has expired. In addition,

customers are advised to obtain and read the MSDS for any chemical used for cleaning optics, and for taking necessary precautions. EIT Instrument Markets

makes no claim for the safety of any of these chemicals.

Two common practices are not recommended. Blowing on the optics with the mouth is not recommended; various components of saliva are extremely difficult to

remove from the optics. Ordinary compressed air (sometimes referred to as shop air) should also be avoided because of the difficulty in removing oil from the

optical surface.
