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, 0.01 mg
or 0.001 mg, use the stainless steel breeze break provided
with the balance for more accurate weighing.

 If you want to change the calibration weight (a list
of usable weights is shown on page 23), 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

The value can be adjusted to
five decimal places for the
AD-4212B-101/102 and to six
decimal
places for the
AD-4212B-23.
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.
