16.3. Other Display
When this indicator blinks, automatic self calibration is required. The
indicator blinks when the balance detects changes in ambient
temperature. If the balance is not used for several minutes with this
indicator blinking, the balance performs automatic self calibration. The
blinking period depends on the operating environment.
Advise The balance can be used while this indicator is blinking. We
recommend that you perform automatic self calibration for precision
weighing.
