Appendix A. Glossary
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.
peripheral
Any device designed for use with, and requiring, the CR200(X) (or another
CSI datalogger) to operate.
precision
A measure of the repeatability of a measurement. See also Accuracy,
Precision, and Resolution (Appendix p. 13).
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 (Appendix p. 8).
processing instructions
These instructions allow the user to further process input data values and
return the result to Input Storage where it can be accessed for output
processing. Arithmetic and transcendental functions are included in these
Instructions.
program control instructions
Used to modify the sequence of execution 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.
pulse
An electrical signal characterized by a sudden increase in voltage followed
by a short plateau and a sudden voltage decrease.
regulator
A device for conditioning an electrical power source. CSI regulators
typically condition AC or DC voltages greater than 16 V to about 14 VDC.
