Factor and Offset adjustments
A factor adjustment can be made to enable readings of
differing orders of magnitude to be charted on the same
scale. For example, a X10 factor applied to ambient
temperature readings would enable them to be charted
alongside process temperatures of 200
o o
400 /1470 F. Factor adjustments can be greater or less than
one.
Offset adjustments can be applied to any trace to adjust its
position with respect to the scale. For example, the readings
from a particular instrument may be known to be 4
due to poor siting of the sensor. An adjustment of +4 in the
Offset column will remove this error.
