The information presented in this section is provided for Users that are attempting to collect data at faster rates such as Samples per Second Users utilizing the OM 320 for data collection at slower rates eg Samples per Minute may opt to skip this section and refer to it later when faster rates are required Due to the nearly unlimited flexibility and potential variations of Program Net designs it is difficult to specify the actual speed performance of Program Nets In an attempt to relate to the OM 320 User a feel for the Program Net processing speeds to be expected the following guidelines are presented Additionally a number of example Program Nets are provided in Appendix B with their approximate execution speeds From this information a feel for the speed of execution of most Program Nets can be developed Program Net Performance Guidelines The time required for a Program Net to execute within the OM 320 is a function of a number of variables including Total number of icons the Program Net with a greater number of icons to process each time the Program Net loops more time is required Type of icons different types of icons require various amounts of time to process For example a Thermocouple input icon requires a considerable amount of processing time to perform the analog to digital conversions CJC measurements and the associated math On the other end of the speed spectrum a Data Memory icon mer

When 4 wire is selected a second corresponding icon Channel B or D is removed as this second channel is required for the 4 wire measurement 4 Wire Compensation Theory With a 4 wire configuration the excitation current flows to and from the element through one pair of leads The actual voltage developed across the element is then measured using a second pair of Sense leads that conduct a very small amount of current hence adding negligible voltage measurement error The 4 wire configuration as the name implies requires the use of four discrete wires from the TSA to the element Two of the leads connect to one end of the element and the other two to the other end of the element Due to the fact that the excitation current flows through a separate pair of leads wire gauge temperature effects and connection resistance has no effect on the accuracy of the readings The Sense leads connected to terminals 4 5 or 10 11 can be of lighter gauge if desired as a very low current flows through them 4 Wire TSA Connections As can be seen in the 4 Wire Wiring Diagram each channel requires 6 of the 12 terminals Channel A uses terminals 1 through 6 and Channel C uses terminals 7 through 12 The Excitation wires connect from opposite ends of the element and to terminals 1 2 or 7 8 on the TSA A second pair of Sense wires then connects from opposite ends of the element to terminals 4 5 or 10 11 A wire jumper must then be insta
