Appendix A. Glossary<br />
period average<br />
A measurement technique utilizing a high-frequency digital clock to<br />
measure time differences between signal transitions. Sensors commonly<br />
measured with period average include vibrating wire transducers and water<br />
content reflectometers.<br />
peripheral<br />
Any device designed for use with, and requiring, the <strong>CR200</strong>(X) (or another<br />
CSI datalogger) to operate.<br />
precision<br />
A measure of the repeatability of a measurement. See also Accuracy,<br />
Precision, and Resolution (Appendix p. 13).<br />
print device<br />
Any device capable of receiving output over pin 6 (the PE line) in a<br />
receive-only mode. Printers, "dumb" terminals, and computers in a terminal<br />
mode fall in this category.<br />
print peripheral<br />
See Print Device (Appendix p. 8).<br />
processing instructions<br />
These instructions allow the user to further process input data values and<br />
return the result to Input Storage where it can be accessed for output<br />
processing. Arithmetic and transcendental functions are included in these<br />
Instructions.<br />
program control instructions<br />
Used to modify the sequence of execution of Instructions contained in<br />
Program Tables; also used to set or clear flags.<br />
Public<br />
A CRBASIC command for declaring and dimensioning variables. Variables<br />
declared with PUBLIC can be monitored during datalogger operation.<br />
pulse<br />
An electrical signal characterized by a sudden increase in voltage followed<br />
by a short plateau and a sudden voltage decrease.<br />
regulator<br />
A device for conditioning an electrical power source. CSI regulators<br />
typically condition AC or DC voltages greater than 16 V to about 14 VDC.<br />
