Section 11. Glossary Ping A software utility that attempts to contact another specific device in a network. Poisson Ratio A ratio used in strain measurements equal to transverse strain divided by extension strain. v = ‐(εtrans / εaxial). precision A measure of the repeatability of a measurement. Also see the appendix Accuracy, Precision, and Resolution (p. 473). PreserveVariables PreserveVariables instruction protects Public variables from being erased when a program is recompiled. print device Any device capable of receiving output over pin 6 (the PE line) in a receive‐only mode. Printers, "dumb" terminals, and computers in a terminal mode fall in this category. print peripheral See print device (p. 464). processing instructions These instructions allow the user to further process input data values and return the result to a variable where it can be accessed for output processing. Arithmetic and transcendental functions are included in these instructions. program control instructions Used to modify the execution sequence of instructions contained in program tables; also used to set or clear flags. Public A CRBasic command for declaring and dimensioning variables. Variables declared with Public can be monitored during datalogger operation. 464
