Chart Recorder Charts and Pens

Charts are designed for single-use to ensure accurate and clear recordings. Reusing charts can lead to overlapping data, making interpretation difficult and potentially compromising data integrity. It’s recommended to use a new chart for each recording cycle.

Dickson chart recorders are designed to monitor multiple parameters, such as temperature and humidity. It’s essential to use charts and pens that are specifically designed for your recorder to ensure accurate readings. For instance, Dickson provides charts and pens tailored to their recorders, and using genuine Dickson charts is required for accurate readings. Pens are available in blue and red to designate humidity and temperature. Pens can be purchased in 6-packs of either blue or red, or a combination pack (3 red, 3 blue).

Step 1: Inspect the Pen. Check for any visible damage or ink depletion.

Step 2: Replace the Pen. If the pen is out of ink or damaged, replace it with a compatible one. For example, Dickson offers replacement pens for their recorders.

Step 3: Check Alignment. Ensure the pen is properly aligned and making contact with the chart paper.

Step 4: Consult the Manual. Refer to your recorder’s user manual for troubleshooting tips specific to your model.

Step 5: Check the Dickson knowledge base.

Charts: Replace the chart after each recording cycle, which could be daily, weekly, or monthly, depending on your recorder’s settings.

Pens: The lifespan of a pen varies based on usage and environmental conditions.  Pens can typically last from six months to one year. Regularly inspect the pen’s ink level and writing quality, and replace it when the ink is depleted or the writing becomes faint.

It’s crucial to use charts that are compatible with your specific recorder model. Using non-compatible charts can lead to inaccurate readings and potential damage.

To install a new chart correctly:

1. Remove the Old Chart: Lift the pen arm away from the chart and remove the old chart.
2. Place the New Chart: Align the new chart on the chart hub, ensuring it’s centered and secure.
3. Set the Time: Rotate the chart hub to align the current time with the time indicator on the chart.
4. Lower the Pen Arm: Gently place the pen arm back onto the chart to resume recording.
