3.6.4 Using the Protective Cover for Field Measurements
The Protective Cover ( Figure 8 ) prevents bright light and rain from
interfering with sample measurements. Use the Protective Cover
when both of the following conditions occur:
1. Tall cells (multi-path or 25-mL sample cells) are used in Cell
Compartment #2 (these cells prevent the sliding door from
closing).
AND
2. The instrument is used outdoors in bright sunlight.
Most other conditions do not require use of the Protective Cover,
however in some lighting conditions the error message “Too much
ambient light! Move instrument into shade or close the lid!” may
appear. If this warning appears, either close the lid, move the
instrument away from direct sunlight, or place the Protective Cover
over both sample compartments (
Figure 9 ).
The Protective Cover can also be used in rainy weather to prevent
water from entering the cell compartments. The enclosure rating of
the instrument increases from IP41 to IP42 when the Protective
Cover is in place.
The inside of the Protective Cover can be used for storage of three
cell adapters (
Figure 8 ). The cell adapter recesses in the Protective
Cover are marked with the corresponding letters and arrows of the
adapter. The arrows indicate the direction of insertion. When a cell
adapter is in use and removed from the cover, the Light Shield can
be stored in the Protective Cover.
Positioning the Protective Cover
1. After the sample is placed in the cell compartment, position the
Protective Cover over both cell compartments. The lettering
“Protective Cover” must be readable from the display side of
the instrument (
Figure 9 ).
