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 frequency
10 kHz (-0,1 dB) 
20 kHz (-1 dB)
Deviation
DC transfer error (with 10 kΩ load) < 10mV
After calibration
additional 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.
