Cleaning the covers
Caution!
The surfaces of the system may be permanently damaged if samples or dis-
persants are spilt on them. If a spillage occurs, disconnect the system from
the power supply before carefully cleaning it up.
Periodically clean the covers thoroughly using a mild soap solution.
Never use excessive liquid for cleaning and always avoid electrical components
(connectors etc.) and the cell windows.
Never use a solvent based solution for cleaning; it may damage the surface.
Cleaning the cells and accessories
Clean cells thoroughly between measurements, especially between different types
of sample. Cross-contamination between samples can seriously affect the results.
Please refer to the
Zetasizer Nano Accessories guide
for information on clean-
ing and maintaining the cell and accessories associated with the Zetasizer nano
instrument.
Replacing the system fuse
Warning!
Fuses must not be replaced by the operator. Only the supervisor or a Mal-
vern representative should attempt to change the fuse.
If the instrument does not power up, check the system fuses. These are in the
mains power switch on the rear panel.
Before changing a fuse, disconnect the instrument from the mains power.
Pull the fuse holders out and replace faulty fuses with others of the following spec-
ification:
Rating – T 2A L 250v (T = Time delay)
Size – 5mm x 20mm
