Section 11. Glossary
measurement requires linearization by means of a Steinhart-Hart or
polynomial equation. CRBasic instructions Therm107() , Therm108() , and
Therm109() use Steinhart-Hart equations.
Term. time domain
Time domain describes data graphed on an X-Y plot with time on the X axis.
Time-series data are in the time domain.
Term. throughput rate
Rate that a measurement can be taken, scaled to engineering units, and the
stored in a final-memory data table. The CR1000 has the ability to scan
sensors at a rate exceeding the throughput rate. The primary factor
determining throughput rate is the processing programmed into the CRBasic
program. In sequential-mode operation, all processing called for by an
instruction must be completed before moving on to the next instruction.
Term. TTL
T ransistor-to- T ransistor L ogic. A serial protocol using 0 Vdc and 5 Vdc as
logic signal levels.
Term. TLS
T ransport L ayer S ecurity. An Internet communication security protocol.
Term. toggle
To reverse the current power state.
Term. UINT2
Data type used for efficient storage of totalized pulse counts, port status
(status of 16 ports stored in one variable, for example) or integer values that
store binary flags.
Term. unconditioned output
The fundamental output of a sensor, or the output of a sensor before scaling
factors are applied. See conditioned output
(p. 510).
Term. UPS
U ninterruptible P ower S upply. A UPS can be constructed for most
datalogger applications using ac line power, an ac/ac or ac/dc wall adapter, a
charge controller, and a rechargeable battery. The CR1000 needs and
external charge controller.
Term. user program
The CRBasic program written by you in Short Cut program wizard.
Term. USR: drive
A portion of CR1000 memory dedicated to the storage of image or other files.
