    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]no use with low-impedance input resistances (especially not suitable for sensors, temperaturesare exposed to over?200 ? C)
    [4]details: see PCBs Declaration of conformance PS024. CE conformity is only guaranteed, if the housing is earthed.
