6. ADJUSTMENT
● Manual adjustment
The manual adjustment requires multiple samples that have known standard
values (composition values). Measure each sample for the specified number
of times, and calculate the average value from the results. Then, compare it
with the standard's average and obtain the difference. The obtained differ-
ence will be the bias value. The better bias accuracy can be obtained by
manual adjustment, since multiple samples are measured multiple times.
● Automatic adjustment
By following the instructions indicated on the
screen, a bias adjustment using a standard
sample can be automatically performed.
Procedure
(1)
Press the [Adjustment] key.
(2)
Press the [Manual Adjustment] key.
(3)
Press the value of the composition
to adjust, and enter the bias value
that has been manually calculated.
Change the value with [+]/[-] keys,
and then press the [Enter ] key.
(4)
Pressing the [Home ] key will
restore the initial screen.
Procedure
(1)
Press the [Adjustment] key.
(2)
The measured value of the standard
sample will be displayed. If the dis-
played value and the value indicated
on the label of the standard sample are
the same, press the [AUTO ADJ.] key.
If the value is different, enter the value
indicated on the label of the standard
sample. Press the value to change,
and make changes with [+]/[-] keys.
Then, press the [Enter ] key.
(3)
After this, follow the instructions on the
screen and perform the measurements
of the empty case, standard sample, and
standard sample after reversing the case.
It will complete the automatic adjustment.
Ex. 1)
When bias value is "+0.5"
(Standard value - Measured
value = +0.5)
Enter the "current value + 0.5".
If the current value is "+0.6",
enter "+1.1".
Ex. 2)
When bias value is "-1.3"
(Standard value - Measured
value = -1.3)
Enter the "current value - 1.3".
If the current value is "-0.7",
enter "-2.0".
