8.1. Calibration Group
Calibration
Calibration using a weight that you have
Calibration test
Calibration test using a target mass
Caution
Do not allow vibration or drafts to affect the balance during calibration.
Calibration test does not perform calibration.
To output the data for GLP using the RS-232C interface, set "GLP output (
info )" of "Data
output ( dout )". Refer to "10. Function Table".
Calibration test is available only when "GLP output ( info )" of "Data output ( dout )" is set .
Caution on using an external weight
The accuracy of an external weight can influence the accuracy of weighing.
Select a mass for calibration and calibration test from the following table.
Model Usable calibration mass Adjustable range
HR-300i 100g, 200g*, 300g -15.0 mg to +15.9 mg
HR-202i 20g, 50g, 100g, 200g* -15.00 mg to +15.99 mg
The calibration mass in bold type: factory setting
The calibration mass value can be adjusted within the range above.
Display
This indicator means "In process of measuring calibration data".
Do not allow vibration or drafts to affect the balance while the indicator is
