PEN PANEL
Pen Pointers
Pens on the chart are specified by Pen Select control (Refer to 4.1.3). When the storing rate and/or the display rate
are set to 0.5 sec., plottable number of pens is limited to four (4) pens (Figure 4.1), while twelve (12) pens (Figure
4.1.1a) can be plotted at once in any other combination of the two rates.
Figure 4.1.1a: Trend view, 12 pens.
Pen pointers are vertically offset to each other so that each pointer can be recognized even when multiple pointers
are positioned at the same input value. No Pen No. indication is provided with the 73ET.
The number 1, 2 or 3 indicated at the left and right ends indicates the current page. Touching the number switches
the pages.
