Operation and handling

First value suppression

After a limit value has been exceeded, a reference measurement is carried out every 4 minutes
to evaluate the result. This prevents false alarms due to the counter ion effect after a system
shutdown.

The LIMESBase and the LIMESPlus are factory-equipped with a fixed activated first value
suppression.

Trigger conditions for an analysis start

•

Automatically by the set analysis interval

•

Manual analysis by pressing the "Start" button

•

3 minutes after switching on the unit

•

4 minutes after a limit value has been exceeded

•

Switching on a connected flow monitor after system standstill

•

Through a connected external control
