ECFt20 Probe User's Manual <br />2. About the ECH2O Probes <br />Below is a diagram showing the wiring configuration for <br />this connector. <br />Wiring to Non -Decagon Dataloggers <br />Models with stripped and tinned leads are pre -configured <br />for connecting to non -Decagon dataloggers. Simplywire <br />the lead into the datalogger as described in "Connecting to <br />a Dataloggee' in Chapter 4. <br />If your model uses the standard 3.5mm plug, you have <br />two choices when attaching ECH20 probes to non -Deca- <br />gon dataloggers. First, you can clip off the plug on the <br />probe cable, strip and tin the wires, and wire it directly <br />into the datalogger. This has the advantage of creating a <br />direct connection with no chance of the probe becoming <br />un -plugged; however, it then cannot be used in the future <br />with a Decagon Em50 or Em5 logger. The other choice is <br />to obtain an ECH20 adapter cable from Decagon. The S- <br />wire probe adapter cable has a connector for the ECH20 <br />probe jack on one end, and three wires on the other end <br />for connection to a datalogger (this type of wire is often <br />referred to as a "pigtail" adapter). Both the probe wire and <br />adapter cable wire have the same wire output (shown in <br />0 <br />�J <br />ii <br />0 <br />G' <br />J <br />n <br />L <br />C <br />0 <br />Fj <br />r <br />L <br />C <br />
