GLOSSARY OF TERMS
ACCURACY: Expressed in percent of end scale rating and indicates the maximum deviation to be obtained from the actual input
value. The percent is always of end scale value and, if the zero is at a point other than one end of the scale, the sum of the end-scale
readings will be the considered the end scale value.
ANSI C39.1 STANDARD: American National Standards Institute Inc. Standard C39.1 applies to analog instruments, defining nomen-
clature, test conditions, and procedures, general construction requirements, mounting dimensions, and performance requirements.
DAMPING: Term applied to the characteristics of the pointer movement once electrical energy is applied and specifically to the
ability of the pointer to indicate properly, quickly with a minimum amount of overshoot or oscillation before coming to rest.
REPEATABILITY: Usually expressed as a percent of full scale, repeatability is the ability of an instrument to read over and over again
the same input.
SELF-SHIELDING: Inherent in the construction, unaffected by stray magnetic fields.
TRACKING: The ability of an instrument to indicate at the division line being checked, when energized by corresponding propor-
tional value of actual end-scale excitation, expressed as a percentage of actual end-scale value.
For zero center meters, tracking from each end-scale point to the zero point should be checked independently and expressed as a
percentage of the end-scale value. For offset zero meters, the larger end-scale value should be used.
VU METERS - VOLUME LEVEL INDICATORS: Hoyt VU meters are for measurement of sound or noise leveles including all instances
where volume level measurements are to be made. This instrument is essentially a low range rectifier type voltmeter using the
D’Arsonval type movement. Hoyt VU meters can be ordered with a type “A” or “B” scale, in a variety of case styles, ranging from 1-1/2” .
2-1/2” , 3-1/2” & 4-1/2” in 2000 and 3100 series meters. Special options available at extra cost include LED for peak measurements and
illumination provisions.
