    notes
    [1] tested with a voltage source and a capacitor (to simulate of a sensor)    
     
    [2] Above the specified rate, it comes to errors due to the low maximum rise and drop speed of the charge amplifier.    
     
    [3] the lower cut-off frequency tolerance: ±20%    
     
    [4] details: see PCB Declaration of Conformance PS024. CE conformity is only guaranteed, if the housing is earthed.
