3.10 CALIBRATE CHART
This page allows the printhead zero and span positions to be set to chart zero and span. On initiation, the printhead
traces lines on the chart where it thinks zero and span are. If incorrect, the positions can be adjusted using the up
arrow key to move the trace slightly to the right, or the down arrow to move it to the left.
Note: Zero (center of chart) setting should always be carried out before the span (outer edge of chart)
setting. The chart must be turned OFF to access this function.
