21. Terms/Index 

21.1. 

Terms 

Calibration 

Adjustment of the balance so that it can weigh accurately.   

Calibration weight 

A weight used for calibration.   

Data number 

Numbers assigned sequentially when weighing data or unit weight is stored.   

Digit 

The minimum weighing value available. Used for the balance, one digit is 
the smallest mass that can be displayed.   

Environment 

Ambient conditions such as vibration, drafts, temperature, static electricity 
and magnetic fields which affect the weighing operation. 

External weight 

A weight that you have.   

GLP 

Good Laboratory Practice.   

GMP Good 

Manufacturing 

Practice. 

 

Internal mass   

Built-in calibration weight.   

ISO 

International Organization for Standardization 

Micro tube 

2 mL and 1.5 mL micro tubes in the market can 
be weighed with the micro tube holder.   

 

Repeatability 

Variation in measured values obtained when the same mass is placed and 
removed repetitively. Usually expressed as a standard deviation. 

Example:  "Standard deviation = 1 digit " means that a weighing error may occur within 

±1 digit in the frequency of approx. 68% when weighing the same mass 
repeatedly.  

Re-zero 

To set the display to zero.   

Sensitivity drift 

An affect that a change in temperature causes to the weighing data. 
Expressed as a temperature coefficient. 

Example: Temperature coefficient = 2 ppm/°C, If a load is 10 g and the temperature 

changes by 10°C, the value displayed changes by the following value. 
0.000

 

002 ppm/°C x 10 °C x 10 g = 0.0002 g 

Stabilization time 

Time required after a sample being placed, until the stabilization indicator 
illuminates and the weighing data is displayed.   

Tare 

To cancel the mass value of a container which is not to be included in the 
weighing data. Normally, refers to an operation of placing a container and 
setting the display to zero.   

Target weight 

An external weight used for calibration test 

Zero point 

A weighing reference point. Usually refers to the value displayed when 
nothing is on the weighing pan. 

1.5 mL  2

 

mL 

 Micro tube 

Micro tube holder
