Automatic Self Calibration (For Variation Of Ambient Temperature); One-Touch Calibration (For Common Use) - A&D BM-20 Manual

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 state). Refer to "9.1. Permit Or Inhibit" for the operation.
Caution
Place nothing on the weighing pan during automatic self calibration.
If something is on the weighing pan, the balance decides that it is in use and does not
perform automatic self calibration.
When weighing a light sample, using long term weighing, installing the balance in a system
or considering the importance of the continuous data, turn off automatic self calibration.
When turning on the balance with nothing on the pan, if a sample heavier than 0.5 g is
Note
placed on the pan, the balance detects the state that a sample is placed on the pan and
does not perform the automatic self calibration.
The mark
When the balance detects a change in ambient temperature, this indicator blinks
and automatic self calibration is required. If the balance is not used for several
minutes with this indicator blinking, the balance performs automatic self calibration.
The environment will affect the time that the indicator blinks.
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.
Advise
The balance can be used while the indicator blinks. But, it is recommended that 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.
