1 Point Adjustment
】
This adjustment method changes only the offset
(
b
)
where the slope
(
a
)
is
considered 1.
For example, TR-71U is measuring 10
℃
, but the standard says the actual
measurement should be 10.2
℃
. Enter 10 in the Before Adjustment box and
10.2 in the After Adjustment box. The conversion equation will be Y
＝
X
＋
0.2
and for all measurements an adjustment to the offset of +0.2 will be made.
【
2 Point Adjustment
】
The adjustment equation will be calculated from two points: the slope
(
a
)
and the
offset
(
b
)
.
For example, the TR-71U reads 0
℃
when the standard thermometer reads 0.4
℃
,
and TR-71U reads 10
℃
when the standard says the true measurement is
10.2
℃
. In this case the slope
(
a
)
is 10.2
-
0.4
/
10
-
0
＝
0.98. The offset is 0.4, so
the conversion equation becomes Y
＝
0.98X
＋
0.4. The range of the slope is
0<a<
＝
2. Entries are valid to one decimal point, but after calculation up to four
digits are valid for the slope and offset.
３.
Enter the adjustment values.
４.
By clicking the
[
Send Settings] button, the adjustment settings will be
completed.
●
The data logger can store up to 4 adjustment values, the adjustment
history will display up to 4 channels at one time.
●
[
Save File
]
button
Assign a name to the adjustment setting values and save them to a file.
●
[
Read File
]
button
Read adjustment setting values from a saved file.
