Open the measuring device in a de-energized state only.
• Before removing the device: set the process in a safe condition and
purge the pipe of dangerous materials.
• Hot surfaces! Risk of injury! Before commencing work, allow the
system and measuring device to cool down to a touchable
temperature.
