Notes for measuring operations
CAUTION
Risk of respiratory problems due to leaking acetic acid vapors
The electrolyte solution of the "high sensitive" measuring cells contains high concentra-
tions of acetic acid.
¡
Ensure that the exhaust hose is connected to the measuring cell.
Check if the exhaust hose is connected to the "waste" outlet on the rear of the detec-
tion module, and that it is connected to the exhaust system.
¡
Before measurement operations, always close the front door of the detection mod-
ule and switch on the laboratory exhaust system.
WARNING
Risk of chemical burns
Concentrated sulfuric acid is used in the detection module as a drying agent. The con-
centrated acid can lead to severe chemical burns.
The 100 % acetic acid (glacial acetic acid), nitric acid and thymol used to create the elec-
trolyte solution can lead to severe chemical burns.
¡
Wear protective clothing when working with these hazardous substances.
¡
Observe all instructions and specifications in the safety data sheets.

147).
The "sensitive" and "high con-
centration" measuring cells
Fill the measuring cells with fresh electrolyte solution daily:
¡
"sensitive" measuring cell: 15 to 20 ml
¡
"high concentration" measuring cell: 120 ml
The "high sensitive" measuring
cell
Fill the measuring cell daily with electrolyte solution: to approx. 65 ml
Change the electrolyte solution:
¡
Once per week
¡
If analytical problems occur
¡
If crystalline deposits form
Open the refill opening of the reference electrode during operation.
