Stable value The weight data when the stabilization indicator appears.
Environment Ambient conditions such as vibration, drafts, temperature, static electricity and
magnetic fields which affect the weighing operation.
Store To save the weighing data, unit mass or calibration data 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, a unit of minimum 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 500 g and the temperature
changes by 10C, the value displayed changes by the following value.
0.0002%/C x 10C x 500 g = 10 mg
