Operation Guidelines

Once the chart paper is installed, ensure optimal recording by observing the following:

• Pen Contact: Verify that the recording pen(s) maintain consistent contact with the chart paper without dragging or skipping. Adjust pen pressure if necessary, following your recorder's specific instructions.
• Time Alignment: Periodically check that the chart paper's time markings align with the actual time to ensure accurate data correlation.
• Environmental Conditions: Ensure the recorder operates within its specified environmental conditions to prevent damage to the paper or inaccurate readings.
• Regular Monitoring: Routinely check the chart paper for proper rotation and pen function, especially during critical monitoring periods.

Care and Maintenance

Proper care and storage of your CR87-9 chart paper will ensure its longevity and accuracy:

• Storage: Store unused chart paper in its original packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
• Handling: Handle chart paper by the edges to avoid fingerprints, creases, or damage to the recording surface.
• Expiration: While chart paper does not typically expire, prolonged exposure to adverse conditions can affect its quality. Use within a reasonable timeframe after purchase.

Troubleshooting Common Issues

If you encounter issues related to the chart paper, consider the following:

• Paper Not Rotating: Ensure the paper is correctly seated on the spindle and the recorder's motor is functioning. Check for any obstructions.
• Pen Not Recording: Verify the pen is properly attached and has sufficient ink (if applicable). Check pen pressure and ensure it makes proper contact with the paper.
• Inaccurate Readings: Confirm that the correct chart paper type (CR87-9) is being used for your recorder model and application. Ensure the recorder itself is calibrated.
• Paper Jams/Creases: Ensure the paper is loaded flat and without wrinkles. Inspect the recorder for any internal components that might be catching the paper.
