Frequently Asked Questions

If the pen does not respond to pressure changes there may be a clog in the capillary. The unit will need to be serviced by Dickson.

Make sure the chart is not hung up or restricted.

Make sure the pen does not have too much tension, pinching the chart to the dial plate.

Make sure there is a good battery being used and it's in correctly.

Make sure the center strip of the chart is inserted properly into the black center hub of the recorder, making sure the chart is not ripped or torn.

Is Pen Arm screw secure?

Is the Chart Recorder sitting on or mounted to a surface prone to vibration?

For Temperature units try removing the unit from the application and placing it in an isolated, low air flow environment like a zip lock freezer bag or desk drawer. If the pen traces straighten out, the traces may have actually been caused by the changes in your application.
