4. Extended operating functions
The functin switch S 60 on the side of the analyzer has three
settings which allocate various modes to the ”Select” ,
”Enter o ” and ”Test u buttons.
Switch position 0: Input mode (auxiliary function) and test mode
Switch position 1: Fine-tuning mode (mean values)
Switch position 2: Fine-tuning mode (upper-range values)
The function switch S 60 is normally concealed by a protective cover. In calibrated devices, this cover is also secured by a calibration
seal. This seal must be removed if you have to work in fine-tuning mode. After this, the exhaust-gas analyzer must be re-calibrated.
The switch position 0 is the standard setting.
In this setting, the functions described in Sections 4.1 (Input mode) and 4.2 (Test mode) may be used.
The following applies to all three operating modes:
A particular function can be selected and indicated on the display by pressing the "Select" button once or several times.
This function is activated by simultaneously pressing the "Enter u ” button.
Once this function has been activated, settings or parameters can be modified by means of the ”Enter o “or ”Test u “ buttons.
Pressing the "Select" button again terminates the function and accepts the modified settings or parameters. The next possible function
is displayed.
For further details on these operating functions, see Sections
- 4.1 Input mode (switch S 60 at position 0, auxiliary functions)
- 4.2 Test mode (switch S 60 at position 0)
- 4.3 Fine-tuning mode (switch S 60 at position 1, mean values)
- 4.4 Fine-tuning mode (switch S 60 at position 2, upper-range values)
If you suspect a malfunction in one of these control elements, perform trouble-shooting in accordance with Section 8.15, "Checking
the sensor board".
