Model 109 Temperature Probe 7. Installation If you are programming your datalogger with Short Cut, skip Section 7.1, Wiring to Datalogger, and Section 7.2, Datalogger Programming. Short Cut does this work for you. See Section 4, Quickstart, for a Short Cut tutorial. 7.1 Wiring to Datalogger TABLE 7-1. Wire Color, Function, and Datalogger Connection Wire Color Wire Function Black Voltage-excitation input Red Analog-voltage output Purple Clear Bridge-resistor lead EMF shield Datalogger Connection Terminal EX, VX (voltage excitation) SE (single-ended, analog-voltage input) AG or (analog ground) G (power ground) 7.2 Datalogger Programming Short Cut is the best source for up-to-date datalogger programming code. Programming code is needed when: • Creating a program for a new datalogger installation. • Adding sensors to an existing datalogger program. If your data acquisition requirements are simple, you can probably create and maintain a datalogger program exclusively with Short Cut. If your data acquisition needs are more complex, the files that Short Cut creates are a great source for programming code to start a new program or add to an existing custom program. NOTE Short Cut cannot edit programs after they are imported and edited in CRBasic Editor. A Short Cut tutorial is available in Section 4, Quickstart. If you wish to import Short Cut code into either Edlog or CRBasic Editor to create or add to a customized program, follow the procedure in Appendix A.1, Importing Short Cut Code into a Program Editor. Programming basics for CRBasic and Edlog dataloggers are provided in the following sections. Complete program examples for select dataloggers can be found in Appendix B, Example Programs. If the 109 probe is to be used with long cable lengths or in electrically noisy environments, consider employing the measurement programming techniques 6
