8.2.Automatic Self Calibration
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
Caution
When using automatic self calibration, do not place something on the weighing pan. 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 or installing the balance in a system, turn off automatic self calibration.
Note 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 the automatic self calibration.
The mark | is " prior notice indicator of automatic self calibration". |
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.
8.3.One-Touch Calibration
This function calibrates the balance using the internal mass.
The only operation required is to press the
CAL
key.
1 Connect the AC adapter and warm up the balance for at least one
hour with nothing on the weighing pan.
2 Press the CAL key to display Cal in
.
3The balance 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 is set,
the balance displays glp and outputs the calibration report using
the 
output (info)" and "Data memory (data)" of the function table.
5 The balance will automatically return to the weighing mode after calibration.
6Confirm weighing accuracy using calibration test (CC in).
