From fundamental weighing terms to the professional terms, terms regarding weighing are widely listed.
A
- Adjustment of an instrument
- The work to setup an instrument to the proper operating conditions for use
Note: Adjustment can be automatic, semi-automatic, or manual - Analog instrument
- An instrument whose analog indication instrument output or display is the continuous function of measured quantity or input signal
C
- Calibration
- The value of the quantity indicated by an instrument or a measuring system
D
- Dead zone
- The maximum range that allows the stimulation to vary in both directions without causing any variation in the response of an instrument
- Drift
- The mild variation in measuring characteristics of an instrument
E
- Eccentric Error
- The difference in the weighed values in the center of the pan and any other position of the pan
- Electromagnetic balance system
- A method to detect the mass of a substance to weigh while bringing it to a balanced point using electromagnetic force and reading the current
- Error of an instrument
- The result of subtraction of the true value from the indication of an instrument
I
- International Standard
- A standard established by international agreement and internationally used as a basis for the evaluation of relevant value to another standard
J
- JCSS weight
- A weight accompanied by a certificate of calibration bearing the logo mark of JCSS (Japan Calibration Service System)
L
- Linearity
- The degree of deviation of a weighed value from a straight line that connects the zero point and the weighing point
- Load Cell
- A load type transducer that outputs a signal in relation to the applied weight or force
- Load Cell Method
- The method of detecting the weight using a load cell
M
- Management of a standard
- The work required to maintain the measuring characteristics of a measuring standard within the proper limits
- Measuring Standard
- A measuring system aimed at defining, realizing, storing, and recreating for the purpose of providing one or multiple values of a certain unit or quantity as a reference
- Minimum indication
- The smallest value to read the weight
N
- National Standard
- A standard established by a national decision and domestically used as the basis for evaluation of relevant values to another standard
O
- OIML
- A weight accompanied by a certificate of calibration bearing the logo mark of the OIML (International Organization of Legal Metrology)
P
- Precision of an instrument
- The ability of an instrument to give a response close to a true value
R
- Repeatability
- The capability of an instrument to show almost similar indications when an identical measuring quantity is measured under identical measuring conditions
- Reproducibility
- To indicate an identical measured value whenever the identical raw material is measured
- Resolution (of an indicator)
- The minimum difference between the two indications of an indicator significantly recognizable
- Response characteristic
- The relationship between stimulation and the corresponding response under certain conditions
- Response time
- The time interval between the point of sudden change of stimulation with a designated value to the point when the response stays within a designated limit for the final stable value
S
- Scale interval
- The difference in the values of the neighboring two scale marks
Note: The scale interval is indicated with the unit described on the scale regardless of the unit of the measured quantity - Sensitivity
- The change of response in an instrument divided by the change in the stimulation
- Span
- The absolute value of the difference in the two limit values within the nominal range
Example: If the nominal range is -10 V to +10 V, then the span is 20 V.
Note: In some academic fields, the difference in the maximum and minimum values is called the range - Specified measuring instrument
- A measuring instrument used for trading certification
- Stability
- The ability of an instrument to maintain the measured characteristics constant in reference to time
- Standard substance
- A substance or material whose single or multiple characteristic values are sufficiently established for the calibration of an instrument, evaluation of measuring method, or certification of a substance
T
- Traceability
- The nature of the measured result or a standard value in relation to a defined standard, which is normally a national standard or an international standard, through a continuous chain of comparison with fully specified uncertainties
U
- Uncertainty
- An estimated value implying the presence range of a true measured value
W
- Weighing capacity
- The weighable maximum mass
