Difference between deviation measurement mode and offset correction
The offset correction function is similar to the deviation measurement mode
with respect to the behavior when a predefined value is subtracted from the
measured value. On the other hand, the two functions differ as explained
below.
If the deviation measurement mode and the offset correction are both ON, the
offset correction is executed first and then, using the result as the
measurement result, the value calculated is displayed. (Refer to Figure 5-1 on
page 92.)
Purpose Effect on comparator
Deviation
measurement
mode
Used when calculating the
deviation of the measured value
from any given value (for
example, nominal value).
Not affected.
The absolute value of the
measurement result is
always used for sorting
judgment.
Offset correction
Used to bring the measured
value close to any given value
(for example, to compensate
variations of the measured value
among instruments for the same
DUT).
Affected.
Values compensated by this
function are used for sorting
judgment.
