3.2 Sensor Connection

1. After the sensors have been mounted, route the sensor leads through the entry

hole in the bottom of the enclosure and to the datalogger. Secure the leads to
the left side of the enclosure using cable ties and tabs (Figure 3.2-1). Any
excess cable should be neatly coiled and secured to the tabs.

2. To connect a lead wire, loosen the appropriate screw terminal and insert the

lead wire (wires should be stripped 5/16”), and tighten the screw using the
screwdriver provided with the datalogger.

If a datalogger program has been developed, the sensors will have to be wired
to the channels specified by the measurement instructions.

If a program has not been developed, Short Cut can be used to generate a
program and wiring diagram. Run Short Cut, and wire the sensor leads as
specified by the wiring diagram in the .DEF file.

For more complex programming, or when sensors are used which are not
supported by Short Cut, CRBasic (PC400 or LoggerNet) must be used. If
desired, wire the sensors and develop the program using CRBasic and the
measurement instructions as shown in Section 5.
