7. Calibration
7-1. Calibration Group
The balance has the following modes as a calibration group.
Calibration
Automatic self calibration (Calibration due to changes in temperature)
Calibration using the internal mass (One-touch calibration)
Calibration using an external weight
Calibration Test
Calibration test using an external weight (Calibration test does not perform calibration)
Correction of the internal mass value
Terms
The following terms are defined as follows:
Internal mass = Built-in calibration weight
External weight = A weight that you have. Referred to as a calibration weight when
used for calibration.
Calibration weight = A weight used for calibration
Target weight = An external weight used for calibration test
Caution
Calibration adjusts the balance for accurate weighing.
Besides periodic calibration and before each use, perform calibration when:
The balance is installed for the first time.
The balance has been moved.
The ambient environment has changed.
Do not allow vibration or drafts to affect the balance during calibration.
To output the data for GLP using the RS-232C interface, set "GLP output ( info )" of
"Data output ( dout )". Refer to "9. Function Table". Time and date can be added to the
GLP report. If the time or date is not correct, adjust them. Refer to the GX-K manual
"10-7. Clock and Calendar Function".
Calibration test is available only when "GLP output ( info )" of "Data output ( dout )" is set to
"1" or "2",
The calibration and calibration test data can be stored in memory. To store them, set "Data
memory ( data )" to " 3 ". Refer to the GX-K manual "12. Data Memory" for details.
The value of the internal mass may change due to aging, corrosion or other damage
caused by the operating environment. Check the internal mass periodically. Correct the
internal mass value as necessary.
