(p. 412).
An example of a pulse sensor connection is illustrated in figure Pulse Input
Wiring Example — Anemometer Switch
(p. 76).
Pulse sensors have two active
wires, one of which is ground. Connect the ground wire to a
(signal ground)
terminal. Connect the other wire to a P terminal. Sometimes the sensor will
require power from the CR3000, so there may be two added wires — one of
which will be power ground. Connect power ground to a G terminal. Do not
