General settings for sensor
Designation Settings Description
Start position Measurement
Maintenance Indicates in which mode the converter is to switch following start-up / Power on.
Measurement
The converter switches to measuring mode. The analogue outputs are active.
Maintenance
The converter remains in maintenance mode, the analogue outputs are switched to
Hold.
Manual release by pressing the Measurement button on the converter is necessary.
Check type Off
Normal
Moderate
Strict Indicates under which criteria the functionality of the electrodes is to be monitored.
Off
Electrode monitoring only during calibration.
Normal
Constant checking using standard tolerances.
Moderate
Constant checking using tight tolerances.
Strict
Constant checking using minimum tolerances.
Recommend setting in standard applications: "Off".
Zero balance Manual
Automatic Manual
Null balance occurs during the next calibration in each case. Specifically for large
measuring ranges. This setting is used in the normal case.
Automatic
For use when measuring is undertaken consistently in the lower measuring range. Null
balance then occurs internally. Increases precision in the lower measuring range.
Setting analogue outputs
Designation Settings Description
mA range 0 .. 20 mA
4 .. 20 mA Set the type of analogue signals here
Start point 000.0 ppm Enter the start concentration for 0 or 4 mA
Finish point 000.0 ppm Enter the finish concentration for 20 mA
Setting threshholds (relay control)
Designation Settings Description
Pre-alert 000.0 ppm The pre-alert is triggered if values are exceeded. Set relays are activated.
Alert 000.0 ppm The alert is triggered if values are exceeded. Set relays are activated
Hysteresis 000.0 ppm Adjustable switching threshold
Delay 000.0 min Adjustable time by which an alert trigger can be delayed.
