test
does
not perform calibration.
When using the data output for GLP / GMP using the RS-232C interface, set "GLP output (
info
)"
of the function table. Refer to "
10. Function Table
". Time and date can be added to the GLP
report. If it is incorrect, refer to "
10.7 Clock And Calendar Function
" and adjust them.
Calibration
test
is available only when "GLP output (
info
)" is set .
The calibration and calibration test data can be stored in memory. When using memory, set "Data
memory (
data
)" of the function table. Refer to "
12. Data Memory
" for details.
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.

About the internal mass
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 and correct the internal mass
value if necessary. Refer to "
8.7. Correcting The Internal Mass Value
".
