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 IP64 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 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.
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
IP64 for moisture and dust ingress. If it needs cleaning,
use a damp cloth and mild detergent.

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
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.
