6.3 Judging with Upper and Lower Limit Values (Comparator Measurement Mode)
200
The following three judgment methods are available:
Deviation Percent (%)
*2
Setting (p. 205)
HI
IN
IN
LO
upper limit value[%]
reference value
lower limit value[
%]
Enter reference values and then set percentages corre-
sponding to the reference values as the upper limit and
lower limit
*
1
values.
The calculated values are displayed in deviations (%) from the reference
value.
Percent (%) Setting (p. 203)
HI
IN
IN
LO
upper limit value[%]
reference value
lower limit value[%]
Enter reference values and then set percentages corre-
sponding to the reference values as the upper limit and
lower limit
*
1
values.
The calculated values displayed are the same as those of the calculation
parameter.
Absolute value (ABS) setting (p. 202)
HI
IN
LO
upper limit value
lower limit value
Set absolute values for the upper limit and lower limit val-
ues of the calculation parameter.
The calculated values displayed are the same as those of the calculation
parameter.
*2: The following equation is used to calculate the % value.
% =
|reference value|
measurement value-reference value
×100
*1: The following equation is used to calculate the comparison upper limit value and comparison lower limit value.
(In the case of the comparison lower limit value, if a value that is lower than the reference value is set, the minus
(-) sign is required for the percentage setting value.)
Upper limit comparison value (Lower limit comparison value) = reference value+ |reference value| ×
100
Percentage set value
• The comparator judgment is made in the following order.
1. If the calculated value is “DISP OUT”, HI is displayed.
2. Whether the calculated value is higher than the lower limit value is judged, and LO is
displayed if the judgment is NG.
3. Whether the calculated value is lower than the upper limit value is judged, and HI is dis-
played if the judgment is NG.
4. If other than 1, 2, or 3, IN is displayed.
No test is performed to ensure that the upper limit value is greater than the lower
limit value, so no error message will be displayed if you set the upper limit value
and lower limit value the wrong way around.
• If the power is turned off while the comparator measurement screen is displayed, the
comparator measurement screen will be displayed when the instrument starts the next
time you turn the power on.
• Comparator measurement can be used even if only the upper or lower limit value has
been set.
