5.5.2.3 Scale Grid
The scales are shown on top of the chart with the major and minor divisions. The grid printed on the chart
is the vertical continuation of the major divisions. For the log scales, the major and minor divisions are
fixed with nine minor and one major division for each decade.
NOTE: If the number of decades between the ends and the mid point of the scale is greater than eight, the
minor and major divisions are not printed. If the grids are too fine they may appear as a solid line
on the display which may not be able to resolve them.
To program the grid use the UP (
↑) or DOWN (↓) Arrow Keys to highlight “Scale grid” and press ENTER.
The display will show “Major →XX←” which is the number of vertical grids that will be printed on the screen.
Use the numeric keypad to enter the number of major grids and press ENTER. The display will show
“Minor
→XX←” which is the number of vertical stripes that will be printed between the major grids on the
screen. Use the numeric keypad to enter the number of minor grids and press ENTER.
5.5.2.4 Scale Units
A five character engineering units field can be programmed for each scale, which is shown at the top of the
graph (see Section 3.2.5.4). This scale unit along with the Engineering units is also recorded to disk. The
same line also identifies the pens trending in the scale with the point number associated to each pen.
Refer to Section 3.5 for an example.
Use the UP (
↑) or DOWN (↓) Arrow Keys to select the “Scale units” and press ENTER. The display
prompts for “units →XXXXX←”. Use the Alphanumeric Keypad to enter the Scale Units and press ENTER.
The display returns to the Scale Units menu item. Press EXIT three times to return to the “COMMAND”
prompt. The rest of the scales are programmed in the same way.
5.5.3 Pens
In the Pens menu, any point programmed into the Recorder can be assigned to any of the pens. The pens draw
the actual traces on the display and are not necessarily the points recorded to disk. You also have the option
to assign any abnormal pen condition (Overrange, TCBO, etc.) to go hi or go low and to select the width of the
pen being displayed on the graph.
