7200 Monitor Instruction Manual
16 Air Clean Setup
The air clean setup and manual air clean menu’s are only display if the air clean option has been enabled on the
sensor setup menu. The air clean option should only be enabled when the 7200 is being used with a Partech air clean
system. If an air clean system is not being used, the following section is not applicable.
Partech air clean systems are designed such that the 7200 Monitor controls when an air clean cycle is performed.
During an air clean, the 7200 Monitor display value, alarm outputs and analogue output are all frozen, and are only
unfrozen once the air clean is complete. During an air clean, a countdown of the remaining time is indicated on the
measure mode status bar.
For further information regarding the air clean system, please refer to the appropriate air clean system instruction
manual.
16.1 Set Clean Interval
The clean interval determines the length of time between the sensor being cleaned. The user can select a clean
interval between 30 minutes and 24 hours, using the value adjustment method of data entry.
Note: The clean interval is entered in hours and minutes. (HH:MM)
16.2 Clean Duration
The length of time that the air pump is running during a clean is set by the clean duration value. The clean duration
should be set to provide adequate cleaning of the sensor for the application in which it is being used.
16.3 Settling Time
The settling time determines the length of time after the air pump has stopped before the instrument returns to live
measurements. The purpose of the settling time is to ensure that the display value is not effected by bubbles or
turbulence caused by the cleaning process.
