Correcting The Internal Mass Value: 2 (Only For The Hr-Az Series) - A&D HR-250AZ Instruction Manual

8-5 Correcting the Internal Mass Value: 2 (Only for the HR-AZ series)

The HR-AZ series balance can correct the internal mass value using an external weight.
Method 2: Calibrate the balance using the external weight. The balance performs automatic
calibration using the internal mass, corrects the internal mass value and stores it in
the balance. The corrected mass value is maintained in non-volatile memory even
if the AC adapter is removed.
The usable calibration weights and the adjustable range are as follows:
Model
HR-100AZ
HR-150AZ
HR-250AZ
HR-251AZ
The calibration weight in bold type: factory setting
The calibration weight value can be adjusted within the range above.
Operation
1 With the factory setting, the balance can not correct
the internal mass value. Refer to "9. FUNCTION
SWITCH AND INITIALIZATION" and set the internal
mass value correction switch to 1.
2 In the weighing mode, press and hold the SAMPLE
key to display ba5fnc .
3 Press the SAMPLE key several times until C5 in
is displayed.
If C5 in 2 is not displayed, perform step 1.
4 Press the PRINT key to display
Refer to "8-6 Calibration Using an External
Weight", to perform the calibration.
5 After calibration, remove the weight. The balance displays

9 Confirm that the internal mass value has been corrected
properly by placing the external weight used for the
correction procedure on the weighing pan.
If the internal mass value has not been corrected properly,
repeat the procedure to adjust the correction value.
