Automatic Self Calibration - A&D BM series Instruction Manual

About the internal mass
The internal mass may change due to corrosion or other damage caused by the operating
environment, or due to aging. Check the internal mass periodically and correct the internal mass
value if necessary. Refer to "8.7. Correcting the Internal Mass Value".

Automatic Self Calibration

8.2.
Automatic self calibration due to changes in temperature
This function automatically calibrates the balance when the balance detects an ambient
temperature change. If GLP output is selected in the function table, the balance outputs the
calibration report or stores the data in memory. Automatic self calibration functions even if the
display is turned off (standby mode). Refer to "9.1. Permit or Inhibit" for the operation.
Caution
To maintain the calibrated state, keep the weighing pan clear while not in use.
If something is on the weighing pan, the balance decides that it is in use and does not
perform automatic self calibration.
When performing a long term weighing with something placed on the pan, installing the
balance in a system or considering the importance of the continuous data, turn off
automatic self calibration.
Notes
When turning on the balance with nothing on the pan, if a sample heavier than 0.5 g is
placed on the pan, the balance detects the state that a sample is placed on the pan and
does not perform automatic self calibration.
Indicates that the balance detects changes in ambient temperature and automatic
self calibration will start. If the balance is not used for several minutes with this
indicator ( ) blinking, the balance performs automatic self calibration. The blinking
duration depends on the operating environment.
Indicates that the balance is measuring calibration data. Do not allow vibration or
drafts to affect the balance while this indicator is displayed. After calibration, the
balance returns to indicate the previous display.
The balance can be used while the indicator blinks. But, to maintain the accuracy, stop
using the balance and confirm that there is nothing on the pan and allow the balance to
perform self calibration.
BM series
This indicator means that the balance is measuring calibration data.
Do not allow vibration or drafts to affect the balance while the indicator is
displayed.
