8-4. Correcting The Internal Mass Value 1 (Only For The HR-AZ Series)
The HR-AZ series balance can correct the internal mass value using an external weight..
Method 1: Calibrate the balance using the internal mass. Measure the external weight. Calculate the
correction value. And store it in the balance.
The adjustable range of the internal mass value is as follows:
Model Correction Reference Value Adjustable Range
HR-100AZ 100 g
HR-150AZ 100 g
HR-250AZ / HR-251AZ 200 g
-0.0150 g to +0.0150 g
Operation
Example : Correcting the weight value by +0.0003 g in 100 g using the HR-150AZ.
If correcting the weight value by +0.0003 g in 50 g, use the correction value of +0.0006 g as the
correction reference value is 100 g.
1 Perform calibration using the internal mass (one-touch calibration).
Place the external weight on the weighing pan to obtain the correction
value.
2 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.
3 In the weighing mode, press and hold the SAMPLE key to
display ba5fnc .
4 Press the SAMPLE key several times until C5 in 1 is displayed.
If C5 in 1 is not displayed, perform step 2.
5 Press the PRINT key.
Correct the internal mass value using the following keys:
RE-ZERO key
...
To increase the value by one.
MODE key
........
To decrease the value by one.
PRINT key
........
To store the correction value and
display the next menu item of the
function table.
CAL key
...........
To cancel the operation and return to the
weighing mode.
6 Press the CAL key to return to the weighing mode.
7 Press the CAL key to perform calibration using the internal mass.
8 Confirm that the internal mass value has been corrected properly by
placing the external weight on the weighing pan.
If the internal mass value has not been corrected properly, repeat the
procedure to adjust the correction value.
Correct the internal mass by +0.0003 g in
100 g. Calibrate with the corrected internal
mass.
