each acquisition: thus, the peak value being stored is the one related to the single interval be-
tween two subsequent acquisitions. Here are the reasons why two different operating modes have 
been chosen: when the sampling interval is short, all of the pressure measurements together re-
flect quite faithfully the progress of pressure over the time. In case of long intervals, the pressure 
value of each interval and of the absolute peak does not provide any accurate information: know-
ing each peak value between two subsequent samplings provides an additional information about 
pressure changes over the time. 

 

Zero Command 

There could be a little difference between the two inputs of the differential probes and then the in-
strument doesn’t display the value of zero even though the pressure measured for both the probe in-
puts is exactly the same. For this purpose there is a reset command of the differential value: let the 
inputs of the probe open so that they can measure the same pressure and then press the

 reset 

key.  
 

 

 
The message null_A, null_B or null_C appears in the controls bar according to which input  the 
module is connected to. Press the function key corresponding to the input to reset the differential 
pressure: the instantaneous value and the corresponding peak value are set to zero. 
 

Relative measure  

The function  “relative measure” can be applied, selectively for every input channel, to all  pres-
sure probes TP704 and TP705 connected through the interface module PP471.With respect  to 
the analogue function with the  <8/REL>  key, this function can be applied separately to each in-
put channel. 
In order to enable it, press the key<+/->  in the command bar. The symbol “Ref” appears, fol-
lowed by the letter that identifies the input channel. By pressing the corresponding function key 
(F1, F2 or F3), the instruments displays the difference between the current value and the value 
when the key has been pressed.  
The activation of the function is marked by a small “r” letter beside the letter A, B or C which 
identify the input channel. To disable the function, press the function key again.
