Repeatability Test

Repeatability is an index of variation in weighing values when the same mass is repeatedly

loaded and unloaded. Standard deviation is generally used for the indicator of repeatability.

The repeatability test measures the internal mass 10 times and displays the standard deviation.
Use the repeatability test function to inspect the performance of the balance when changing the

environment or when moving the balance to a new location.

Example: "Standard deviation = 0.2 mg" means that the results of repeated measurements of the

same mass fall within the range of ±0.2 mg at a frequency of about 68%.

Notes

When the password function is used, the repeatability test function is available only when
logged in as an administrator (

The repeatability test uses the internal mass. Therefore, the obtained standard deviation
may disagree with that of the repeatability of "

20. Specifications

". Regard the standard

deviation as a reference.
