Since this is much less than the end-to-end resistance of a zener barrier, it may be necessary to specify a monitor intended for use without a barrier. Please follow the advice of the monitor manufacturer.

Transfer characteristics

Cut-off frequency10 kHz (-0,1 dB)

20 kHz (-1 dB)

DeviationDC transfer error (with 10 kΩ load) < 10mV

After calibrationadditional error with AC superimposed is ±5 mV at 20 °C (68 °F) at any point within the span, provided that the alternating component of the input voltage is not excessive, e. g.

- square waves (0 ... 20 kHz): 5 Vpp

- sine waves (0 ... 20 kHz): the full span of 20 Vpp (= 100 g peak acceleration at 100 mV/g) is acceptable.

Influence of ambient temperature(< 100 ppm of span)/K at any point within the span

Time delay relative to input7.1 ±0.3 µs
