Step Programming
1 Access the extended functions
• Press the Mode/Enter button until EF is displayed.
• Press the Set button. bin is now displayed, the first
parameter of the extended menu.
• You can scroll through the parameters by pressing the
Mode/Enter button.
• You can access the corresponding parameter value by
again pressing the Set button.
2 Select Switching mode / Binary mode
Factory setting: Switching mode; bin = OFF
Please skip this step if you want to maintain the factory
setting.
3 Selection of the display unit
Set the required display unit: cm / inch.
Select the display unit before setting values for the para-
meters (SPx, rPx, OP). This avoids rounding errors gener-
ated internally during the conversion of the units and
enables exact setting of the values.
Setting at the factory: Uni = cm.
Please skip this step if you want to maintain the factory
setting.
4 Setting to the medium
Return to the main level of the menu (by repeatedly
pressing the Mode/Enter button).
Set the appropriate sensitivity for the medium and the
appropriate mode of detection.
The following settings can be chosen:
• MEDI = CLW1 for water, coolant emulsions, hydrous
media.
• MEDI = CLW2 for hydrous media with temperatures
> 35°C (mounted in the climatic tube).
• MEDI = OIL1 for special (e.g. synthetic) oils or media
with a dielectric constant that is a little higher than
that of mineral oils.
• MEDI = OIL2 for mineral oils (DK ≈ 2).
Also select the setting MEDI = OIL1 if the medium is
detected with MEDI = OIL2 but on the whole the sensor
sensitivity is too high. In case of doubt ensure the correct
function by performing a test in your application.
