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.
The same mass
100.0000 g 100.0003 g
Corrected mass value
The balance displays
-0.0150 g after +0.0150 g.
