4.5 Internal display and control elements of the LT 2/KS1-DK lambda transmitter
The LT 2/KS1-DK is operated and the measurement values, process status and fault
status signals are displayed via the display and operating unit (see section 4.6), or via
PC in conjunction with the remote display software. The LT 2/KS1-DK itself features
only limited operator controls, which nevertheless permit the initiation or display of all
functions necessary for operation, maintenance and service directly on the LT 2/KS1-
DK as well.
