Automatic Self Calibration
This function automatically calibrates the balance, when the balance
detects an ambient temperature change.
When the balance detects a change in ambient tem­
perature, this indicator blinks and automatic self calibra­
tion is required. If the balance is not used for several
minutes with this indicator blinking, the balance pre­
forms automatic self calibration. The environment will
affect the time that the indicator blinks.

This display means "the balance is measuring calibra­
tion data". Do not allow vibration or drafts to affect the
balance while this indicator is displayed.
Advice
You can use the balance while the indicator blinks. But, it is recommended
that to maintain the best accuracy, stop using the balance and confirm that
there is nothing on the pan when the indicator starts blinking.
Caution
□ Do not place anything on the weighing pan during automatic calibration.
Control of Automatic Self Calibration
Automatic self calibration is controlled by a parameter in "Permission or
prohibition". Refer to section "8. Function Switch and Initialization"
