3.6 Mobile use of the DR 2800 for field analysis
If the DR 2800 spectrophotometer is used to carry out field
analyzes, it may be necessary to take a number of measures to
compensate for the fluctuating ambient light conditions.
You should take the measures described below if the following
warning is displayed after you take a measurement:
Error: Too much ambient light! Move device into shade or
close the lid!
General measure:
Shield the instrument from the sun by standing so that your shadow
falls on it, and carry out the measurement again. If the warning
appears again, take the following measures.
Measures:
Measurements in a 10 mL round cuvette/cell, a rectangular
cuvette/cell or AccuVac Ampules
Close the lid of the cuvette compartment and carry out the
measurement.
Measurements in a 13 or 16 mm round cuvette/vial or a 25 mL
square cuvette/cell
To obtain consistent measurement conditions in all weather
conditions, place the Protective Cover on the open cuvette/cell
compartment (see Figure 9 Position the Protective Cover on page
20) and carry out the measurement.
Important Note: When you carry out measurement in 25 mL
square cuvettes/cells, take care that there is no adapter in the
Protective Cover.
The enclosure rating of the photometer increases from IP41 to IP42
when the Protective Cover is in place.
