ESD
Electrostatic discharge.
ESS
Environmental sensor station.
excitation
Application of a precise voltage, usually to a resistive bridge circuit.
execution interval
The time interval between initiating each execution of a given Scan() of a CRBasic program. If
the Scan() Interval is evenly divisible into 24 hours (86,400 seconds), it is synchronized with
the 24 hour clock, so that the program is executed at midnight and every Scan() Interval
thereafter. The program is executed for the first time at the first occurrence of the Scan()
Interval after compilation. If the Scan() Interval does not divide evenly into 24 hours,
execution will start on the first even second after compilation.
execution time
Time required to execute an instruction or group of instructions. If the execution time of a
program exceeds the Scan() Interval, the program is executed less frequently than
programmed and the Status table SkippedScan field will increment.
expression
A series of words, operators, or numbers that produce a value or result.
F
FAT
File Allocation Table - a computer file system architecture and a family of industry-standard
file systems utilizing it.
FFT
Fast Fourier Transform. A technique for analyzing frequency-spectrum data.
