General Operating Principles Switching On Switching on the controller Representation of keys and displays: Example: Pressing the ”Communication” button causes the mode to change to the ”Communication with the measuring heads” mode of operation: Required action: press button. The instrument displays: The current date and time appear (important for the allocation of sample numbers). If the date/time is incorrect, undertake corrections in ”GLP/Tools”.

Supplement to the operating manual Supplement to the operating manual After reconfirming the data of the measuring head is read out and stored in the controller. Restore data In case you lost your controller or your controller is defective, the “Restore data“ function facilitates to restore the data of running measurements using a new or another controller. This means the data are not lost. The Id number of the sample is not restored, it is always I999.
