Step 6: Install sensors to the optional Analog Sensor Port.
Make sure all
wires attached to the Analog Sensor Port are routed through the cable access
opening. For details on configuring the Analog Sensor Port with HOBOware
Pro, see page 32.

Tip: Because these cables will need to fit into the holes in the rubber cable
channel, the ideal cable diameter is 0.157 in (4.0 mm). If the cable is
too small, build up the diameter using heat shrink. If it is too big and
you are using the secondary cable access opening, then place the cable
through the leftmost hole in the rubber cable channel where the
diameter can be up to 0.25 in (6.4 mm). If you are not using the
secondary opening or the cable is still too big, then splice on another
cable with a smaller diameter to fit through the hole. See the steps later
in this section for working with the rubber cable channel.

Step 7: Install the optional relay output wire.
Make sure any wire you use
is routed through the cable access opening (see the tip in the previous step
about recommended cable diameter). For details on configuring alarms to
activate the relay, see page 28.
