8-2 Calibration Test
This function tests the balance weighing accuracy using the calibration weight and outputs the result.
This is available only when the “GLP output (info)” parameter is set to “1” or “2”. (Calibration test
does not perform calibration. Display example: AD-4212B-102)
Operation
1 Plug in the AC adapter and warm up the balance with nothing on the pan.
• AD-4212A series balance: 30 minutes or more
• AD-4212B series balance: one hour or more
For the models with a minimum display of 0.1 mg or 0.01
mg, use the stainless steel breeze break provided with the
balance for more accurate weighing.
2 Press and hold the CAL key until CCout is
displayed, then release the key.
3 The balance displays CC 0 .
If you want to change the calibration weight (a list
of usable weights is shown on page 21), press
the SAMPLE key and proceed to step 4.
If you use the calibration weight value stored in
the balance, proceed to step 5.
If you want to cancel calibration test, press the
CAL key. The balance will return to the weighing
mode.
4 Specify the calibration weight value as follows:
SAMPLE key To switch the operation to:
calibration weight selection
mode (All of the segments
blinking) or value adjustment
mode ( Digits to be changed
blinking).
With the AD-4212B-101/102,
the value can be adjusted
down to five decimal places.
RE-ZERO key To select the calibration
weight or adjust the value.
PRINT key To store the new 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 CC 0 .
