There are 15 comparator setting tables in the 3227, and the different contents
are able to set to each table.
See Section 5.1, "Setting the Comparator" and Section 5.2, "Executing the
Comparator", for how to set and execute the comparator. See Chapter 6,
"External Control Terminals", for the external control terminals.
The comparator is valid only in the resistance measurement mode, and unable
to use in the temperature measurement mode.
The comparator and the auto range should be used separately.
While displaying the converted temperature, the 3227 has only one
comparator setting table. The comparator tables for normal resistance
measurement cannot be used. In this case reference value/range comparisons
also cannot be executed.
(1) Executing the comparator
The result of the comparator is displayed as follows.
Displayed value > High limit value
High limit value ≧ Displayed value ≧ Low limit value
Low limit value > Displayed value
The result of the comparator is able to output to the external control terminal.
In the over range and the NG states, the comparator result is HIGH.
(2) Comparison method of the comparator
Comparison according to high limit value/low limit value
Comparison according to standard value/range
Comparison value
High limit value = standard value + (｜standard value｜×range ÷ 100)
Low limit value = standard value - (｜standard value｜×range ÷ 100)
