POSITION S2
The upgrading of the number of sensors can be easily done by the user by performing the following directions:
- Both the expandable instruments are arranged in a way to accept one or two additional sensors in positions S3
and S4.

- Identify, with the help of paragraph 5.2 'Sensor types and relevant positioning' the sensor(s) which must be
added to the existing configuration (Seitron delivers all FLEX-series sensors already pre-calibrated and ready
to use).
- To install the new sensors follow all the steps described in the paragraph 'MAINTENANCE' under 'gas sensors
replacement'.
THE INSTRUMENT AUTOMATICALLY DETECTS WHEN AN ADDITIONAL SENSOR IS
INSTALLED OR HAS BEEN REMOVED. THE SCREEN 'SENSORS CONFIGURATION'
