Page 16: Maintenance, Cleaning
® Operation pHotoFlex Maintenance, cleaning Maintenance The meter is almost maintenance-free. The only maintenance task is replacing the batteries or rechargeable battery. NOTE Make sure the poles of the batteries are the right way round. The ± signs on the batteries must correspond to the ± signs in the battery compartment. - Page 17 ® pHotoFlex Operation (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: CAUTION Cells can contain poisonous or corrosive substances.
