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 follow
by a short plateau and a sudden voltage decrease.
regulator
A record is a complete line of data in a data table or data file. All data
on the line share a common time stamp.
regulator
A device for conditioning an electrical power source. Campbell Scientific
regulators typically condition ac or dc voltages greater than 16 Vdc to
about 14 Vdc.
resistance
A feature of an electronic circuit that impedes or redirects the flow of
electrons through the circuit.
resistor
A device that provides a known quantity of resistance.
resolution
A measure of the fineness of a measurement. See also Accuracy,
Precision, and Resolution
(p. 471).
ring line (Pin 3)
Line pulled high by an external device to "awaken" the CR1000.
Ring Memory
A memory configuration for data tables allowing the oldest data to be
overwritten. This is the default setting for data tables.
ringing
Oscillation of sensor output (voltage or current) that occurs when
sensor excitation causes parasitic capacitances and inductances to
resonate.
