Clean the meter
The meter is designed to be maintenance-free and does not require
regular cleaning for normal operation. Exterior surfaces of the meter may
be cleaned as necessary.
Note: Do not clean the meter with solvents to avoid damaging the material.
1.
Clean the meter with a dust- and lint-free dry or slightly damp cloth. A
mild soap solution can also be used for liposoluble contamination.
Apply silicone oil to a sample cell
Sample cells and caps must be extremely clean and free from significant
scratches. Apply a thin coating of silicone oil on the outside of the sample
cells to mask minor imperfections and scratches that may contribute to
light scattering.
Note: Use only the provided silicone oil. This silicone oil has the same refractive
index as the sample cell glass.
1.
Clean the inside and
outside of the cells and
caps by washing with a
laboratory glass
cleaning detergent.
Follow with multiple
rinses with distilled or
demineralized water.
2.
Apply a small bead of
silicone oil from the top
to the bottom of the cell.
3.
Use the provided
oiling cloth to spread the
oil uniformly. Wipe off
the excess so that only a
thin coat of oil is left.
Make sure that the
sample cell is almost dry
with little or no visible oil.
Note: Store the oiling
cloth in a plastic storage
bag to keep the cloth
clean.
