1. INTRODUCTION
The UVe-LUX is a compact, lightweight and robust meter specifically designed for
the non-destructive testing environment. The meter is a dual white-light (WL) and
ultra-violet (UV) meter designed to give simultaneous readings of both WL and UV.
The meter has the following specification:
• Single sensor head measures UV and white light at the same time
• 320 x 240 pixel 2.8” TFT colour LCD display
• Dimmable display to extend battery life
• Auto-ranging on both WL and UV scales
• Menu driven setup and multi-function buttons
• ‘Auto Hold’ function to record maximum readings
• Adjustable auto-power down to conserve battery life
• Meets the requirements for non-destructive testing viewing conditions for
penetrant and magnetic particle inspections (ISO 3059)
• Measurement units - WL: lux or fc, UV: μW/cm² 0 m W/cm²
• Measuring range - WL: 0.1 to 5000 lux, UVA: 0 to 10,000 μW/cm²
• Accuracy - WL: better than 5%, UV: better than 5%
• 2 x AA Rechargeable batteries
• Display of time and date
• Save function for logging readings
• Detachable light sensor probe
3.5 POWER OFF TIME
The POWER OFF TIME menu option allows you to
set an automatic timer to power the meter down,
in order to conserve battery power. The power o
timer may be set between 0 and 15 minutes. If the
power o time is set at 0, the meter will never turn
itself o. If the time is set outside the required range,
an ‘ERROR IN TIME’ message will be displayed.

3.6 TIME/DATE
The SET TIME/DATE menu option allows you to
change the time and date settings.
To set the time:
Select the TIME ONLY option from the menu;
‘ENTER CURRENT TIME’ will display. Increase or
decrease the time using the up and down arrow
buttons. Use the left and right arrow buttons to
move between digits, then use the accept button
to complete.

2. SYSTEM COMPONENTS
The system consists of a sensor housing containing both the WL and UV sensors,
and the meter housing containing the main system components such as the
screen, battery and user interface. Both the sensor housing and the meter housing
are constructed from reinforced ABS plastic and are rated to IP65 for moisture
and dust ingress. The two housings are linked together with 750mm of flexible
screened cable for ease of use.
2.1 SENSOR HOUSING
The sensor housing contains the individual WL and
UV detectors in one handy unit. The active area of
the sensor housing is the circular glass panel on
the front of the housing. Ensure that the glass panel
remains clean and is not damaged in any way, as
any dirt or damage to the glass panel will aect the
accuracy of the meter.
If the panel requires cleaning, use a damp cloth
with a small amount of detergent to wipe the panel,
then use a dry, lint-free cloth to dry the panel. Do
NOT use abrasive cleaners and solvents as they
may damage the unit.
If the panel gets damaged, return the whole meter
to the manufacturer for repair and re-calibration.

2.2 METER HOUSING
The meter housing contains the display screen,
buttons and battery for the unit. The meter housing
is rated at IP65 for moisture and dust ingress. If it
needs cleaning, use a damp cloth and mild deter-
gent.

3.1 MEASUREMENT DISPLAY
When the unit is powered up, it will normally enter the measurement display after
the splash screen. The measurement display contains six components:
• Battery level - this gives an indication of the state of the battery life.
• Current time and date.
• WL reading - this is the current rounded reading for the white light sensor.
• WL max - this is the maximum absolute value the meter has observed for white
light. This reading is reset when the cancel button is pressed.
• UV reading - this is the current rounded reading for the UV sensor.
• UV max - this is the maximum absolute value the meter has observed for UV. This
reading is reset when the cancel button is pressed.
If the meter is exposed to light levels greater than its designed range, the meter will
saturate and display ‘9999’ to indicate that it has saturated. The meter will return
to normal operation once the light levels have returned to the meter’s designed
range.

2.4 BATTERIES
The UVe-LUX is powered by two AA type, rechargeable batteries. You can access
the batteries by unscrewing the screw holding the battery housing cover on the
rear of the meter housing, and removing the cover. It is important to insert the
batteries in the correct orientation as marked in the battery compartment, other-
wise damage may occur to the meter. The battery housing cover should then be
replaced and screwed back down.
We recommend that the batteries supplied with the meter should be charged
overnight (the meter must be o whilst the batteries are charging). The charger
supplied with the meter is for the sole purposeof charging the batteries and
must not be used independently (i.e. as an external power adaptor) to run the
meter under normal operating conditions.
Whilst connected to the charger, the top-right of the screen will display ‘CHARGING’.
When the batteries are full, the sreen will display ‘CHARGED’. Once the batteries
are fully charged, the meter will run for approximately eight hours before needing a
recharge. ‘BATTERY LOW’ means the batteries need to be recharged or the meter
will power itself down. Ordinary dry cell batteries can be used and no damage will
result if the battery charger supplied is inadvertently used.

3. DISPLAY
In normal operation, when the unit is powered up, the first screen to appear is the
logo screen, followed by the splash screen. The splash screen contains informa-
tion about the meter, including the serial number and the date of last calibration for
the unit. This screen can also be found in the main menu under ABOUT.
The LCD display is protected behind a protective plastic cover, but take care to
protect the screen area from blows, scratches or other damage.
