With PEn displayed, depressing the SCROLL key will toggle between PEn and ArC. With ArC in the display, press DOWN to
enter the Pen Arc adjustment section. During arc calibration/adjustment, ArC will remain in the display. The pens will move to
the home position and the red pen will then draw an arc upscale.
If the pen is upscale, pressing the DOWN key will cause the selected pen to move downscale. If it is already downscale, the
DOWN key will cause the chart to advance. If the pen is downscale, pressing the UP key will cause it to move upscale. If it is
already upscale, the UP key will cause the chart to advance. Adjust the red pen's "length" and "position" on the inner/outer
ring as needed. Repeat this sequence until the red pen is properly adjusted.
When finished with the red pen, press SCROLL to adjust the green pen. For the green pen, the "length" should be adjusted so
that it almost touches the red pen when they pass each other. Adjust the "position" to align with the inner/outer ring. When
finished with the green pen, press SCROLL to exit. P1Lo will be displayed, as the Pen Span calibration must now be done.
Section 6 Model Number Changes
When adding options to the recorder in the field, it is necessary to change the model number contained within the memory of
the recorder.
The model number is displayed during the power up sequence. The first 8 digits of the model number are displayed in two 4
digit steps. The first displayed value will be the prefix 5, the first pen option, second pen option, and pen 1 output (the first 4
digits of the model number). The next display will show the pen 2 output, communications, case, and voltage options present
on the recorder.
To change the model number, set the MODE switch to the PROG/TEST/CAL position, and power down and power up the
recorder. After the software revision is displayed while the pen(s) go to the home position, the first 4 digits of the model
number will be displayed. Use UP or DOWN to change the number. Press SCROLL and the next 4 digits of the model number
will be shown. Again use UP or DOWN to change the number. Make sure the model number is correct for the hardware
options present.
When complete, depress SCROLL. Refer to section 4.2 to make any programming changes required by the change in
hardware options.
