    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: ±10%
    [4]details: see PCB Declaration of conformance PS024. CE conformity is only guaranteed, if the housing is earthed.
