Maintenance: 
It is recommended to check once a year if the displayed values are 
correct. Two practical check options are: 
- Lift the probe above the liquid level. Then check if ~ 0 L is displayed. 
- Check the cm value displayed in Step ‘10.Trim height’  
 (without trimming!). 
In case of deviation it is recommended to recalibrate the measuring 
probe via menu step 9 or 10. If the problem cannot be fixed the level 
probe might be defective. In this case please directly contact Tecson. 
New measuring probe (level sensor): 
In case of replacement of the level probe it is recommended to call 
menu item ‘9.Probe offset’ and execute the item ’Default values’!
