Cleaning
Occasionally wipe the outside of the measuring instrument with a damp, lint-
free cloth. Disinfect the housing with isopropanol as required.
NOTE
The housing components are made of synthetic materials (polyure-
thane, 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:
3 Close the battery compartment (1).
4 Set the date and time
1 Switch the Turb
®
750 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 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.
Scratches in the glass change the optical characteristics of the
cell and falsify the measured value. For this reason, never use
scratched cells!
