Moreover, the following applies:
• rPx (FLx) is always smaller than SPx (FHx)� If the value for SPx (FHx) is
reduced to a value ≤ rPx (FLx), the position of rPx (FLx) also shifts.
• If rPx (FLx) and SPx (FHx) are close together (approx� 3 x step increment),
rPX (FLx) is changed automatically when SPx (FHx) is increased�
• If there is a greater distance between rPx (FLx) and SPx (FHx), rPx (FLx)
maintains the set value even if SPx (FHx) is increased�
14 Maintenance
Always observe the admissible application area to avoid damage and to
!
►
Keep the ventilation hole and the interior of the coaxial pipe free from deposits
and foreign bodies� Observe application area
►
In case of soiling: Clean probe at regular intervals�If soiling occurs: It is
absolutely necessary to take measures to prevent soiling� Observe application
area
In case of longer operation separation layers can form in the medium
(e�g� oil on water)� It is possible that a separation layer may form inside the
coaxial tube!
►
Remove separation layers at regular intervals (e�g� remove oil by suction)�
