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 information 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.
3.1 Measurement display
Splash screen
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.

1. INTRODUCTION
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, otherwise damage may occur to the meter. The battery housing cover should then be replaced and screwed back down.
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:
We recommend that the batteries supplied with the meter should be charged overnight (the meter must be off 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.
•
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
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.
•
‘Auto Hold’ function to record maximum readings
•
Adjustable auto-power down to conserve battery life

2. SYSTEM COMPONENTS
2.3 Buttons
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 IP64 for moisture and dust ingress. The two housings are linked together with 750mm of flexible screened cable for ease of use.
On/Off button: Press this button (while the unit is off) to switch the UVe-LUX on Hold down this button (while the unit is on) to switch the UVe-LUX off Accept button:
2.1 sENSOR HOUSING
Press this button in measurement mode to enter menu mode Press this button in menu mode to select/approve the highlighted menu function.
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 affect 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.
