4.15 Setting and Activating the Comparator

NOTE
3. Select the units using one of the units keys:
:
step the units up
:
step the units down
p--n--μ --m--(none)--k--M
<= Units down Units up =>
Pressing the key causes the upper limit value to be set and the screen
display to return to the Conditions setting screen.
4. The lower limit value is set in a manner identical to the upper limit value,
mutatis mutandis.
The setting can be made in the range : -200.00M to +200.00M
5. When the setting for the upper or lower limit value has been established as
above, press the key on the Condition setting screen to return to the
Comparator screen.
The comparator decisions are made in the following order:
1) If the measured value is "OVER FLOW", HI is displayed, and the value is
"UNDER FLOW", LO is displayed.
2) Is the measured value greater than the lower limit value or not?
If not (NG decision result), then LO is displayed.
3) Is the measured value lower than the upper limit value or not?
If not (NG decision result), then HI is displayed.
4) If both 2) and 3) give an affirmative result, then IN is displayed.
No test is performed in order to ensure that the upper limit value is greater
than the lower limit value. Therefore no error message will be displayed
even if you mistakenly interchange the settings for the desired upper limit
value and the desired lower limit value. However, be careful that the
decision process will not operate properly.
