4.3 Control Concept

The main function and sub-function groups are organised in a matrix format as shown below. These

functions can be accessed via the front keypad for configuration and selection of parameters.

The controller offers two levels of password protection: (1) for direct access to calibration function and

(2) for setting or editing specific controller parameters or functions in the SETUP mode to suit individual

requirements.

Note: The passwords are not user-defined and have been set by factory. It is very important to keep

these passwords strictly confidential to avoid unauthorised tampering of the system at all times.

Note: If the user reads parameters only, the controller automatically reverts to Measurement mode if

none of the keys is pressed for 30 seconds.
