    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.
    (T) TEDS memory in accordance with IEEE PP1451. 4
    temperature range -40 … 185 ° F -40 … 85 ° C
    Bias voltage 13.35 … 14.85 V DC
