5.5.3 Pens

Using 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 high or go low and to select the
width of the pen being displayed on the graph.
To program the Pens:
From the Chart/Pens menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Pens and then press the ENTER
button. You will have three choices: Pens assign, Abnorm. pen, Trace Width. The options are described in
the following sections.

5.5.3.1 Pens assign

To assign a point to a Pen:
Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Pens assign and press the ENTER button. The display
will read "pen 1 = pt X". Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select the point to assign to pen 1 and press
the ENTER button. Repeat to assign points to pens 2-C. You need not program all pens. Any pen programmed
to point 0 will be turned off. At any time you may press the EXIT button to cancel any changes.

5.5.3.2 Abnorm. Pen

Any time a pen goes into an abnormal condition (Overrange, TCBO, etc.), the pen can go full scale if high
is selected or low scale if low is selected.
To set the Abnormal Pen condition:
Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Abnorm. pen and press the ENTER button. Use the UP
(↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select abnorm. pen high or abnorm. pen low and press the ENTER button.
Press the EXIT button to return to the Pens menu.

5.5.3.3 Trace Width

The pen trace widths can be changed from 1 to 7 pixels wide. This value changes all pens displayed.
To change the pen Trace Width:
Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Trace Width and press the ENTER button. Use the UP (↑ ↑ ↑ ↑ ↑ )
or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select a width value (in pixels) and press the ENTER button or press the EXIT
button to cancel any changes.

5.5.4 Direction

Direction determines whether the traces on the Trend View move in a vertical or horizontal direction. The
direction may be changed at any time without affecting the recording or the browse buffer.
To change the direction of the chart:
From the Chart/Pens menu, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Direction and press the ENTER
button. Use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select either vertical or horizontal and press the ENTER
button. The chart will change direction immediately, clearing the screen and beginning a new trace. Press the
EXIT button to return to the Chart/Pens menu.
