To 100% (Note 1): Auto Range Codes
Code “1” allows setting the range in which the full scale is
always 10 X 10n, as in the case of 0 to 10 ppm, 100 ppm,
1000 ppm, 1%, and so on.
Set code “2” if 20 X 10n applies, as in the case of 0 to 20 ppm,
0 to 200 ppm, 0 to 2000 ppm, 0 to 2%, and so on. Likewise,
codes “1” to “9” can be set.
Range of 0 to 100 ppm is confirmed
The above is an example of setting the fixed range of 0 to 100 ppm.
(Note 2)
How to set the manual fixed range
Select one of the six ranges as follows:
0 to 10 ppm,
0 to 100 ppm,
0 to 1000 ppm,
0 to 1%,
0 to 10%,
0 to 100%.
To set the partial range, set the MANUAL Range and
then the Hi/Low values of Partial Range (Note 3) .
For details of the numerical value, decimal point,
and unit operation in the partial range, see Section 6.6.
To 10 ppm
(Example of setting 50 to 90 ppm) (Note 3)
To set a partial range, select “FrEE” with the ▼ key.
Then, set the Hi/Low values. However, if the Hi and Low values are reversed,
or the span (the smallest width) is not larger than 20%FS of the MANUAL Range,
an input error occurs (the display flashes).
Enter the high value in the patial range.
Enter the numerical value, decimal point, and unit.
The high value is confirmed.
(the range of 50 to 90 ppm is confirmrd).
Enter the low value in the patial range.
Enter the numerical value,
decimal point, and unit.
The Low value is confirmed
(the range of 50 to 90 ppm is setting).
Return to “rnG.”
