8-2 Automatic Self Calibration
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). ,
Caution
If something is on the weighing pan, the balance judges that it is in use and does not perform
automatic self calibration. To maintain the calibrated state, keep the weighing pan clear while
not in use.
The displays shown below are related to the automatic self calibration.
Note
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.
8-3 Calibration Using the Internal mass
This function calibrates the balance using the internal mass. The only operation required is to press
the CAL key
Operation
1 Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on the
weighing pan.
2 Press the CAL key.
3 The balance displays Calin and performs calibration using the internal mass. Do not allow
vibration or drafts to affect the balance.
4 The balance displays end after calibration. If the "GLP output (info )" parameter of the
function table is set to "1 " or " 2 ", the balance displays glp and outputs the "Calibration
Report" using the RS-232C interface or stores the data in memory. For details on the
calibration report format, refer to "11-2 GLP Report".
5 The balance will automatically return to the weighing mode after calibration.
About the internal mass
The value of 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. Correct the internal
mass value as necessary. For details, refer to "8-6 Correcting the Internal Mass Value".
To maintain the weighing accuracy, perform the calibration using an external weight periodically,
as described below.
Indicates that the balance detects a change in ambient temperature and
automatic self calibration will start. If the balance is not used for a few
minutes with this indicator blinking, the balance performs automatic self
calibration. The blinking duration depends on the 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.
