Cleaning Occasionally wipe the outside of the meter with a damp, lint-free cloth.
Disinfect the housing with isopropanol as required.
Caution
The housing components are made out of synthetic materials
(polyurethane, ABS and PMMA). Thus, avoid contact with acetone
and similar detergents that contain solvents. Remove any
splashes immediately.
Cleaning the cell shaft If liquid is in the cell shaft (e.g. due to a spilled cell), clean the cell shaft
as follows:
Cleaning the cells Cells have to be clean, dry, and free of fingerprints and scratches.
Therefore, clean them regularly:
Note
Scratches in the glass change the optical characteristics of the cell and
falsify the measured value. For this reason, never use scratched cells!
1 Open the battery compartment:
– Unscrew the two screws (1) on the underside of the meter,
– Remove the lid of the battery compartment (2).
2 If necessary, take four old batteries out of the battery
compartment.
3 Insert four batteries (3) in the battery compartment.
4 Close the battery compartment and fix it with the screws.
1 Switch the Turb 430 IR/T off and pull out the power plug.
2 Rinse the cell shaft with distilled water.
1 Clean the cells inside and out with hydrochloric acid or
laboratory soap.
2 Rinse out several times with distilled water.
3 Let them dry in the air.
4 Only hold the cells by the top or by the light protection cap so
that the optical path is not impaired.
5 Before measuring, clean the cell with the enclosed cleaning
cloth.
