1Introduction
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 2.4” colour display.
Dimmable display to extend battery life.
High contrast ratio OLED screen (over 30 x greater than a TFT-LCD in dark conditions and
over 12 x in sunlight).
180°(UD)/180°(LR) viewing angle (over 3 x viewing angle of TFT-LCD in both viewing planes).
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
Measuring range - WL: 0.1 to 5000 lux, UVA: 1 to 10,000μW/cm²
Accuracy - WL: better than 5%, UV: better than 5%
2System 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 out of reinforced ABS plastic and are
rated to IP64 for moisture and dust ingress. The two housings are linked together with 600mm 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. Care should be taken to ensure that the glass
panel remains clean and is not damaged in any way as any dirt or damage to
the glass panel will affect the accuracy of the meter.
Should the panel require cleaning a damp cloth with a small amount of
detergent can be used the wipe the panel, and a dry, lint-free cloth can then
be used to dry the panel. Abrasive cleaners and solvents should NOT be
used as they may cause damage to the unit.
Should the panel become damaged, the whole meter should be returned 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
IP64 for moisture and dust ingress and should it need
cleaning it can be cleaned with a damp cloth and using
mild detergent.
2.3 Buttons
On/Off button: Pressing this button when the unit is off will switch the UVe-LUX on.
Holding this button down when the system is on will switch the system off.
Pressing this button while the system is in measurement mode will reset the max WL
and max UV readings.
Pressing this button while the system is in menu mode will select the currently
highlighted menu function.
Down button: Pressing the down button in measurement mode makes the screen
darker by one count.
Holding this button down in measurement mode will keep decreasing the screen
brightness until the button is released.
Pressing the down button in menu mode will cycle down through the menu options.
Holding the button down in menu mode will keep cycling down through the menu options.
Up button: Holding this button down and then pressing the On/Off button when the
unit is powered off and keeping it held down until after the welcome screen has
appeared will enter menu mode.
In measurement mode pressing this button will lighter the screen by one count.

2.4 The Battery
The UVe-LUX is powered by a single 9V PP3 style battery (K9V X/522 MX/MN 1604 A1604 6AM6
4022/1604A/6LR61). The battery is held in its own compartment which is accessible by unscrewing
the two screws holding the battery housing cover on the rear of the meter housing. Once the cover
has been removed the battery can accessed. The battery can only be fitted in one orientation with
the positive terminal of the battery being connected to the ‘+’ clip in the battery compartment. The
battery should only be fitted in the orientation described, if the battery is forced in the wrong way
round damage may occur to the UVe-LUX meter. The battery housing cover should then be
replaced and screwed back down.
It recommended that the battery should only be replaced with a new battery and not a previously
used one.
Figure 5 Battery compartment
With typical usage the battery should last for approximately 3 months, and should last over 2 years
with the unit powered off. It is recommended to replace the battery every 12 months and to
remove the battery when the UVe-LUX is to be stored for a long period of time without use. When
the battery indicator (see display section) is reading ‘LOW’ the battery should be replaced. The
meter may not give accurate readings when the battery is low.

2.5 Display
The meter is fitted with an OLED display that gives a much higher
contrast and superior viewing angle than traditional TFT or LCD
displays. The display is protected behind a protective plastic cover,
but care should still be taken to protect the screen area from blows or
scratches or other damage.
In normal operation when the unit is powered up, the first screen to
appear is the Logo screen, followed by the Splash screen. The Logo
screen contains information about the meter, including the serial
number and date of last calibration for the unit. Keeping the ON/OFF
button held down during power on will pause the meter at the splash screen until the button is
released.
2.5.1 Measurement Display
When the unit is powered up it will normally enter the
measurement display after the Splash Screen.
The measurement display contains five components:-
Battery level –This gives an indication of the state
of the battery life.
WL reading- this is the current reading for the
white light sensor (this reading is rounded).
WL max –this is the maximum value the meter
has observed for white light (this reading is
absolute). This reading is reset when the
ON/OFF button is pressed.
UV reading- this is the current reading for the UV sensor (this reading is rounded).
UV max –this is the maximum value the meter has observed for UV (this reading is
absolute). This reading is reset when the ON/OFF button is pressed.
If the meter is exposed to light levels greater than it’s designed range the meter will saturate. When
the meter is saturated it will display “>5000” “>10000” or “++++” in red to indicate that it has
saturated. The meter will return to normal operation once the light levels have returned to the
meters design range.

2.5.2 Menu system
The menu system is entered by holding the UP-button down while the system
is powered off and then pressing the On/Off button and keeping the UP-
button held down until after the welcome screen has appeared.
Once in menu-mode the UP and DOWN keys can used to scroll through menu
items and pressing the ON/OFF key is used to select menu items.
Holding the ON/OFF key down for several seconds in menu mode will power the system down.
