The smart connector stores probe calibration coefficients. The 6-pin DIN accepts traditional connectors and the probe coefficients can be entered into the readout or an appropriate characterization curve can be selected through the user interface (see Section 1.5.2 Immunity Testing on page 8 for information on using clamp-on ferrites). A PRT is the only type of probe that is supported by the reference thermometer input. The PRT (RTD or SPRT) probe connects to the reference thermometer input using a 6-pin DIN connector. Figure 8 shows how a four-wire probe is wired to the 6-pin DIN connector. One pair of wires attaches to pins 1 and 2 and the other pair attaches to pins 4 and 5 (pins 1 and 5 source current and pins 2 and 4 sense the potential). If a shield wire is present, it should be connected to pin 3, which is also used for the memory circuit. Pin 6 is only used for the memory circuit. 24 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664
