Sensor Span Adjustment
If the zero point of the measuring point is correct but
the highest calibration point is incorrect then the
sensor span adjustment will shift the end point of the
curve up or down. This changes the slope of the
output curve.
The current sensor reading can be seen in the pop-up
window and is adjusted by pressing the up and down
arrows. When the reading is correct press the enter
button to store the adjustment.
The amount of slope adjustment currently being
applied to the sensor is shown in the channels
calibration menu as a %. Where 100% equals no
adjustment, a slope of greater than 100% equals a
steeper slope and a slope of less than 100% equals a
shallower slope.
