Care and Maintenance

The Photometer 7500 Bluetooth contains no user-serviceable
parts internally. User maintenance is only recommended for
cleaning of the optical chamber, changing batteries and
validating performance using the Check Standard Mode.
Cleaning the Optical Chamber
The optical chamber has been designed to support removal
and cleaning with a lint-free cloth as required by removal of
the access cover.
Do not use any of the following agents when cleaning this
optical chamber:

Abrasive cloths

Corrosive chemicals

Any organic solvents
Do not overtighten the screws on re-assembly to avoid
damaging the access cover.
Replacing the Batteries
Remove the four retaining screws from the battery cover and
gently prise the cover free.
Replace all batteries at the same time.
Ensure on replacing the battery cover that the gasket is
correctly located to prevent any water ingress. Tighten the
screws carefully but do not overtighten.
