▶ The device/installation must only be operated by suitably trained staff.
WARNING
Danger due to non-conforming commissioning.
Non-conforming commissioning could lead to injuries and damage the device and its surroundings.
▶ Before commissioning the device, calibrate the conductivity sensor (see chap. 9.12.4).
▶ Before commissioning, make sure that the staff in charge have read and fully understood the contents of the
manual.
▶ In particular, observe the safety recommendations and intended use.
▶ The device / the installation must only be commissioned by suitably trained staff.
▶ Set the correction factor of the fitting used (see chap. 9.12.4).
9.2 Knowing the operating levels
The device has 2 operating levels:
Process level
This level is used:
• to read the measured values of 2 measurable variables selected in the Parameters menu,
• to read both the lowest and highest values of the chosen measurable variable, that have been measured by the
device since the power-up of the device or since the latest reset (this feature is not active by default),
• to reset both the lowest and highest values of the chosen process value, if the feature has been activated,
• to read the current values emitted on the 4-20 mA outputs,
• to get the state of the device and the conductivity sensor with the icons.
