The setting ranges for analogue start point (ASP) and analogue end point (AEP)
depend on the probe length (L)� In general the following applies:
cm inch
min max min max
ASP 1�0 (3�0) --- 0�4 (1�2) ---
AEP --- L --- L - 1�2
Step increment 0�5 0�2
Minimum distance between [ASP] and [AEP] = 25 % of the active zone�
The values apply if [OFS] = 0� The values in brackets apply to the setting [MEdI] = [LOW]
(setting for the detection of oils and oil-based media)�

► Keep the process connection free of deposits and foreign bodies�
► In case of heavy soiling: clean the process connection and the probe at regular
intervals�
In case of longer operation separation layers can form in the medium (e�g� oil on
water)� This applies especially to still pipes or bypasses�
► Remove separation layers at regular intervals�
► Ensure that the vent hole (at the upper end of the coaxial pipe) remains free�
► Keep the interior of the coaxial pipe free from foreign bodies and soiling�
