Filter 
The filter function "

Filt

" generates the sliding average value from the measured 

values. The following values are available (see section 6.2 Settings): 
 
 

1 / 2 / 4 / 8 / 16 / 32 / 64 

 
 
The filter value determines the dynamic behaviour of the indicated value: high 
values result in a slow display response. The filter is disabled if a filter value of "1" 
is selected. In other words, the indicated value is equal to the unfiltered measured 
value. 
 
The integrated step detector responds to a measured-value step change greater 
than approximately 6.25% of the upper range value. When a measured-value 
step change is detected, the actual measured value is displayed immediately. 

 
 
Contact Model 

The function of the transistor switching output is set in menu item "

Con, Co1 or 

Co2

". The switching function switches from 

 

no - N/O contact 

to 

 

nc - N/C 

to 

 

Fr – frequency 

(Con and Co1 only and 
for sensors with impulse 
output)  

 

and back. 

N/O contact means: contact closes when switching point is exceeded 
N/C means: contact opens when switching point is exceeded 
Frequency means: frequency output synchronized with vane frequency 
 
 

Current output 

The current output is selected in menu items  
 

"

S-C

"   Start current  indicated value < > 0(4) mA 

 

"

E-C

"   End current   indicated value < > 20 mA 

 

"

SCS

"   Start current selection (0-20 mA or 4-20 mA). 

The indicated value at which 0(4) mA flow is entered in menu item Start current. 
The indicated value at which 20 mA flow is entered in menu item End current.  
 
 

Change Code 

The change code option "

CCo

" secures the unit against unauthorised tempering. 

If the code is different from 000, the user must input the code immediately after 
entering the adjustment mode.
