FLUO Invisible Ink Densitometer Instruction Manual
FLUO Fluorescence Densitometer▲▲►
The FLUO BASIC Fluorescence measurement device is equipped with near UV (365
nm). The dominant wavelength of the near UV illumination is 365nm
(nanometers).
On the receiver side, there are three channels to measure the fluorescent
effect according to the sensitivity of the human eye, i.e. X (red
sensitivity), Y (green sensitivity), and Z (blue sensitivity).
The FLUO BASIC is supplied with a USB 2.0 cable to output data to a PC.
Safety Instructions
For safety reasons, it is absolutely necessary to read and understand the user’s guide. If the safety recommendations and instructions in this User Guide are not complied with, measurement errors or data loss or physical injury or property damage may result.
- FLUO is not intrinsically safe. Therefore, the device cannot be used in an environment with explosive vapors where there is a risk of spark ignition. It should be protected against strong electromagnetic fields, chemicals, corrosive vapors, strong mechanical vibrations, and impacts.
- Use the FLUO in ambient temperatures between 15°C (59°F) and 40°C (104°F), and do not expose it to direct sunlight.
- The FLUO should never be opened as there are no user-serviceable parts. Doing so voids the guarantee. Contact your authorized dealer if repairs are necessary.
- To prevent the operator from looking directly into the UV light source the FLUO must be placed on a substrate while taking measurements. A sensor detects if it is not placed on a substrate and prevents the UV illumination from being activated. No measurement will take place under this condition.
- To avoid incorrect handling, the FLUO should only be used by trained personnel
- Use only original FLUO spare parts and accessories.
- Use the original packaging exclusively when transporting.
- The FLUO is equipped with UV LEDs. Never look directly into the optical system of the device during measurement, even though it is equipped with a safety interlock.
Important: This manual describes the current version of the FLUO hardware and software. Future enhancements or modifications are reserved.
How to use the FLUO
During a measurement, the FLUO BASIC will calculate three measurement values,
one for X, one for Y, and one for Z.
The FLUO can be used in two modes: the color mode will show XYZ values, the
intensity mode will show only the intensity of the near UV. The mode is
selected in the Configuration shown below.
The LCD shows the actual measurement value. The active light source and the
dominant channel are displayed by the flashing LEDs at the top of the FLUO
device.
Example:
Example 1: green color channel (Y), near UV illumination, Color mode
Example 2: near UV illumination, Intensity mode
RESET the FLUO
Press the RESET button on the bottom side of the device to perform a RESET.
Resetting will delete all internally stored references. The display will show
the device type for a few seconds.
FLUO equipped with near UV LED only
After a few seconds, the display will change and show the current firmware version number
After initialization, the device will show ‘0’. The FLUO is now ready for measurements.
Press the RESET button and keep the right key depressed during reset to
perform a FACTORY RESET. The factory Reset will reset all settings and
configurations to its defaults.
Configure the device to your needs
The FLUO can be configured to your needs in a special Configuration mode.
Press and hold the right key for at least 5 seconds to enter Configuration
mode
The configuration mode is indicated by a ‘~’ in the left top corner of the LCD.
Two settings can be configured:
a) Average Solid Reference
b) Color Mode or Intensity Mode
Click the right key to adjust the Average Solid Reference settings and Color
or Intensity mode selection.
a) Use an average solid reference
The FLUO can be configured to calculate the average of a series of up to 10
readings on your reference patch. The number of readings that need to be
measured to calculate the reference can be set in the Configuration mode.
Averaging multiple readings can be useful when there is unevenness or
variability in the reference patch print quality.
Click the up key on the device to increment the number of readings
Click the down key to decrement the number of readings
b) Select Color display mode or Intensity display mode The FLUO can be used in two different modes.
In Color mode the dominant fluorescent color after any 100% reference reading will be displayed automatically. By clicking the right key after a measurement the next XYZ color channel will be displayed – followed by the XYZ color channels of the near UV readings.
The Intensity mode will display one value, expressing the total brightness of
the light emission within the visual spectrum.
Toggle between the two modes by clicking the left key.
Exit the configuration mode
Press and hold the right key for at least 5 seconds to exit the Configuration mode. The current configuration will be saved.
Zero references and target reference calibration
The FLUO measures relative fluorescence using a non-fluorescent reference (0%
or substrate) and a target fluorescent reference (100% target fluorescent ink
layer). Follow the steps outlined below to set the Zero and Reference values.
Set the Zero reference
**** Position the FLUO with the aperture on a non-fluorescent surface, for
example on the substrate without fluorescent ink. Press and hold the ‘down’
key and push the device to the front until zero appears in the LCD.
All measurement channels will be zeroed simultaneously.
Set a single solid reference [C 0]..[C 1]
If the average number in the settings is set to zero, the calculation of an
average is disabled.
Position the FLUO with the aperture on the fluorescent reference surface, for example on the substrate with fluorescent ink. Press and hold the ‘up’ key and push the device to the front until 100 appears in the LCD.
The maximum reference measurement measures all channels simultaneously and sets the maximum fluorescent signal for each illuminant separately to 100%. The channel with the highest fluorescent response will automatically be displayed. When the Intensity mode has been selected the intensity of the reference sample is set to 100% for near UV.
In Color mode, you can check the relationship between fluorescent responses in
red, green, and blue by stepping through the colors by pressing the ‘next’
button.
Measure an average solid reference [C 2]..[C 10]
If the reference measurement average counter is greater than 1, you must take
as many solid reference readings as specified in the setting.
Position the FLUO with the aperture on the fluorescent reference surface, for
example onto the substrate with fluorescent ink. Press and hold the ‘up’ key
and push the device to the front until [C 1] appears in the LCD.
Now measure the next reference again with the middle key ‘up’ depressed.
Continue to measure references until the number of references specified in the
settings is reached. Once all reference measurements are taken, the device
will calculate the average and set this value to 100%
Measure samples in Color mode [CoL ]
Position the FLUO with the aperture on a fluorescent surface. Push the device
to the front and hold it there until the measurement result appears in the
LCD. The measurement value of the currently selected color channel is
displayed.
The LED of the dominant visual color will blink.
The number displayed (79%) tells you that the sample emits only 79% of the
light in the ‘Y’ channel (green) spectrum compared to your reference. This
indicates to the operator that insufficient ink is being applied to the
substrate.
Click the right key to select the next color channel. The color channel
selection will step through all color channels for near UV.
Measure a sample in Intensity mode [Int ]
If your device has been configured to display the intensity only, the
difference between the reference intensity and the sample intensity will be
calculated and displayed in terms of a percentage value.
Position the FLUO with the aperture on a fluorescent surface. Push the device
to the front until the measurement result appears on the LCD. The measurement
value of the currently selected near UV is displayed.
The number -21 tells you that the fluorescent intensity of your sample is 21%
lower than the fluorescent intensity of your reference. This indicates to the
operator that insufficient ink is being applied to the substrate.
The near UV intensity measurement is displayed with RGB LED flashing. The far
intensity is displayed with FUV LED flashing.
Underflow
and Overflow measurements
The FLUO automatically checks the validity of measurement results and displays
a warning in case of invalid measurement:
Underflow
An underflow occurs when the measurement resolution is too low. This can occur
when the fluorescence of the sample is extremely low. In this case, the FLUO
displays uF in the proper measurement channel.
Overflow
The FLUO has a very large dynamic range with Automatic Gain Control. An
overflow error is very rare, occurring only when the fluorescent signal in one
channel exceeds the range of the AGC. The overflow for the affected channel is
then displayed as oF.
Open aperture
For safety reasons, the UV LED will not switch on if the device is not
positioned on a substrate. In this case, the display will show ‘ooo’.
Measurement time too short
Keep the FLUO in the front position until the measurement result appears in
the LCD. If you move the FLUO back to its parking position too early, the ‘—‘
in the LCD tells you that the measurement time was too short.
Replacing the batteries
The FLUO is powered by two 1.5V AA alkaline batteries. No charger is needed as
they will typically last many months in normal service
- Remove the cover from the battery compartment by pressing down on the center near the front of the battery cover and sliding it towards the rear
- Remove the old batteries and dispose of them in accordance with local regulations
- Insert the new batteries with the polarity as shown on the label inside the compartment
- Replace the battery cover
- Always replace always both batteries at the same time
- If you do not use the devices for an extended period of time it is recommended to remove the batteries from the battery compartment.
