Offset (basic value for display and measured value):

The area between the bottom of the vessel and lower face of the measuring 

probe can be entered as offset value� Thus the display and switch points 

refer to the real vessel level�

setting range

Display unit:

2 settings can be selected: 

• EU = display in cm (Europe)

• inc = display in inch

Select the display unit before setting the switch points (SPx, rPx)�

This avoids rounding errors generated internally during the conversion of 

the units and enables

exact setting of the values�
Min-Max memory:

• HI: Displays the highest measured level

• LO: Displays the lowest measured level

Erase the memory:

- Press the "Mode/Enter" button until “HI” or “LO” is displayed�

- Press the"Set" button and keep it pressed until “- - -” is displayed�

- Then press the "Mode/Enter" button briefly�
