• R

Valid for compact ojects

According to OIML R76

After adjustment with built-in reference weight

In the temperature range 10...30 °C

Sensitivity drift/year after putting into operation for the first time, with the FACT self-calibration function activated

Includes sample handling and setting time

With DeltaRange models: Fine range starting at zero gross load

sd = Standard deviation

Rgr = Gross weight

Rnt = Net weight (sample weight)

a = Year (annum)

The minimum weight can be improved by the following measures:

- Selecting suitable weighing parameters

- Choosing a better location

- Using smaller taring containers

- Using an inner draft shield (AX)

The information contained in this document has been carefully prepared and represents the most up-to-date status. Data shown as typical are reference values

for calculation of the expected measurement uncertainty. The actual measurement performance may be affected negatively or positively by the place of use and/

or the settings.
