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 | The weight that you have. |
GLP | Good Laboratory Practice. |
Internal mass | |
IP code: Degree of protection provided by enclosures. | |
| 6: |
Mode | Balance operational function. |
Output | To output the weighing data using the |
Range | A combination of weighing range and resolution. |
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: This means that measured |
| values, obtained when the same sample is placed and removed |
| repetitively, fall within ±1 digit in the frequency of about 68%. |
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 8 kg and the |
| temperature changes by 10°C, the value displayed changes by the |
| following value. |
| 0.0002%/°C x 10°C x 8 kg = 0.16 g |
| In this example, if the value displayed is 8000.00 g before temperature |
| changes, a temperature change of 10°C will make the value displayed |
| 8000.16 g. |
Smart range function | The function allows weighing in the precision range, even if a heavy |
| tare is used. |
