Square root of dielectric Light Attenuation Coefficient Latitude Latitude as a parameter, for example recording moving instrument locations Longitude Longitude as a parameter, for example recording moving instrument locations Battery Voltage The battery voltage of a datalogger or sensing system, often recorded as an indicator of data reliability Flash Memory Error Count A counter which counts the number of datalogger flash memory errors Table Overrun Error Count A counter which counts the number of datalogger table overrun errors Sample Count Recorder for how many samples were taken at a time WatchDog Error Count A counter which counts the number of total datalogger watchdog errors Signal-To-Noise Ratio Signal-to-noise ratio (often abbreviated SNR or S/N) is defined as the ratio of a signal power to the noise power corrupting the signal. The higher the ratio, the less obtrusive the background noise is.
