OPERATION

3.2

LCD screen

3.2.1

Schedule operation LCD screen

The LCD screen in combination with the buttons support a low access level functionality.
Because of its location which is close to the process it is possible to do basic calibrations.
Since retreiving log data will go by USB stick it is possible to set time and date for time stamp values
during log, as well as setting the log interval.

A minor system status displays the most relevant error in case of measurement problems.To assure
settings can only be changed by authorized personal most menu’s are hidden behind an access level.
