Section 11. Glossary output interval The time interval between initiations of a particular data‐table record. output processing instructions Process data values and generate output arrays. Examples of output processing instructions include Totalize(), Maximize(), Minimize(), Average(). The data sources for these instructions are values in variables. The results of intermediate calculations are stored in memory to await the output trigger. The ultimate destination of data generated by output processing instructions is usually final storage, but it may be output to variables for further processing. The transfer of processed summaries to final storage takes place when the output trigger is set to True. PakBus A proprietary telecommunications protocol similar in concept to internet protocol (IP). It has been developed by Campbell Scientific to facilitate communications between Campbell Scientific instrumentation. PakBus Graph software Shows the relationship of various nodes in a PakBus network, and allows for adjustment of many settings in each node. A PakBus node is typically a datalogger, a PC, or a telecommunications device. parameter Argument or parameter? These terms are frequently interchanged, but have a useful distinction. A parameter is part of a procedure (or command) definition; an argument is part of a procedure call (or command execution). An argument is place in a parameter. For example, in the CRBasic command Battery(dest), dest is a parameter and so defines what is to be put in its place. If a variable named BattV is meant to hold the result of the battery measurement made by Battery(), BattV is the argument placed in dest. Example: Battery(BattV) BattV is the argument. period average A measurement technique utilizing a high‐frequency digital clock to measure time differences between signal transitions. Sensors commonly measured with period average include vibrating‐wire transducers and water‐content reflectometers. 461
