29. TERMS/INDEX 
Terms 
Stable value 
The weight data when the stabilization indicator appears. 
Environment 
Ambient conditions such as vibration, drafts, temperature, static electricity or 
magnetic fields which affect the weighing operation. 
Store 
To save the weighing data, unit mass, calibration data or upper/lower limit values 
using the data memory function. 
Calibration 
Adjustment of the balance so that it can weigh accurately. 
Output 
To output the weighing data using the RS-232C interface. 
Zero point 
A weighing reference point or the zero display. Usually refers to the value 
displayed when nothing is on the weighing pan. 
Data number 
Numbers assigned sequentially when weighing data or unit weight is stored. 
Digit 
Unit of digital resolution. Used for the balance, the minimum displayable weighing value 
Tare 
To cancel the weight of a container which is not included in the weighing data. 
Mode 
Balance operational function. 
Re-zero 
To set the display to zero. 
GLP 
Good Laboratory Practice. 
Repeatability 
Variation in measured values obtained when the same weight is placed and 
removed repetitively. Usually expressed as a standard deviation. 
 
e.g. Standard deviation=1 digit: This means that measured values fall within 
±1 
digit in the frequency of about 68%. 
Stabilization time Time required after a sample being placed, until the stabilization indicator 
illuminates and the weighing data is displayed. 
Sensitivity drift  An affect that a change in temperature causes to the weighing data. Expressed as 
temperature coefficient. 
 e.g. 
Temperature 
coefficient = 2 ppm/
°C : If a load is 100 g and the temperature 
changes by 10
°C, the value displayed changes by the following value. 
 0.0002%/
°C x 10°C x 100 g = 2 mg
