4.3 Examples of connecting the external transducers
Connections of the head-mount transducers when the transducers are su-
pplied directly from the N31U meter are shown below. In the case of the trans-
ducers with a voltage output, the maximum current carrying capacity of the
auxiliary supply output is 30 mA and the auxiliary supply source is only active
for selected input ranges of 10V, 20MA and Pot10V.
