MEASUREMENT
4.3.1

An O
measurement using the 9065C consists of the following processes: taking an oxygen
2
measurement and displaying the measured O
times for the oxygen content and the temperature can be set in the "Display times" menu.
Before the measurement, the product-specific parameters can be set in the "Product choice"
menu.
The figures below show the sequence of displays for a measurement:

As soon as the last samples have been measured, the 9065C must be rinsed with cold water. Store
the 9065C either empty or filled with water.

CONTINUOUS MEASUREMENT
4.3.2
2
With this measurement, the oxygen content is measured continuously while the liquid flows
through the 9065C. This option is typically used to check processes where there is a chance of
oxygen getting into the liquid, such as during filtration or when switching tanks.
The measurement is started as follows:
1. Use the throttle valve to slow down the flow in order to reduce the amount of product.
2. Press "Enter" for approximately 1 second.
The continuous oxygen measurement will be started and the current measurement
value will be displayed. The measurement values will be saved in the 9065C based
on the set O

value and the measured temperature. The display
