4.15 Setting and Activating the Comparator
Using the comparator function an upper limit value and a lower limit value
can be set, and the result of measurement then can be compared with these
two limit values, so as to give a result expressed as HI (greater than the
upper limit value), IN (between the lower limit value and the upper limit
value), or LO (less than the lower limit value). Moreover, a corresponding
signal can be output via the EXT I/O connector on the rear panel of the
3532-50 unit.
The following setting methods are available on the comparator:
Absolute value setting method (ABS)
The upper limit value and the lower limit value are set as absolute numerical
values. The measurement values displayed are the same as those of the
measurement parameters.
Percentage setting method (%)
A reference value is input, and the upper-limit and lower-limit values are set
as percentages relative to the reference value. The measurement values
displayed are the same as those of the measurement parameters.
Setting of the deviation percentage (
Δ
%)
A reference value is input, and the upper-limit and lower-limit values are set
as percentages relative to the reference value. The measurement values are
displayed in deviations (
Δ
%) from the reference value.
The comparator can deal with two test values at the most. "ABS", "%", and
"
Δ
%" can be selected for each of these values individually.
After powering off on the Comparator setting screen, the screen is displayed
when the power is turned on again.
