Calibration Using an External Weight
This function calibrates the balance using an external weight.
Note Automatic self calibration (due to changes in temperature) is enabled in the factory
setting. Therefore, even after calibration using an external weight, the balance may
perform automatic self calibration whenever it detects changes in temperature.
When considering the importance of continuous data or managing the balance using the
external weight only, refer to
"
9.1. Permit or Inhibit
" to set the function switch to “inhibit”
1 Connect the AC adapter and warm up the balance for at
least one hour with nothing on the weighing pan.
2 Press and hold the
CAL
key until
Calout
is
displayed, and then release the key.
3 When
Cal 0
is displayed, proceed as follows:
If you want to change the calibration weight, press
the
RANGE
key and proceed to Step 4.
If you use the calibration weight value stored in
the balance, proceed to Step 5.
4 Specify the calibration weight value as follows:
RANGE
key..........To switch blinking digits.
RE-ZERO
(
+
)key.....To select the calibration weight or adjust the
calibration weight value. Refer to page 37.
PRINT
key............To store the new calibration weight value.
Even if the AC adapter is removed, the
data is maintained in non-volatile memory.
CAL
key ...............To cancel the operation and return to
Cal 0
.
5 Confirm that there is nothing on the pan and press the
PRINT
key. The balance measures the zero point.
Do not allow vibration or drafts to affect the balance.
The balance displays the calibration weight value.
6 Place the displayed calibration weight on the pan and press
the
PRINT
key. The balance measures the calibration
weight. Do not allow vibration or drafts to affect the balance.
7
end
is displayed.
Remove the weight from the pan.
8 If GLP output is set,
glp
is displayed and the calibration
report is output and stored. Refer to "GLP output (
info
)" and
"Data memory (
data
)" of the function table in "
11.2. GLP
Report
" and "
12. Data Memory
".
9 The balance will automatically return to the weighing mode.
10 Place the calibration weight on the pan and confirm that the
value displayed is correct. If it is not within the range, check
the ambient conditions such as breeze and vibration, and also
check the weighing pan. Then, repeat Steps 2 to 10.
