    1. Introduction Thank you for purchasing the new PX-20 or PX-30, the latest in Delmhorst’s legacy “P- series” pin-type (conductance) moisture meters from the new Navigator™ family of moisture meters. Delmhorst P-meters are known worldwide for their unmatched reliability and ease of use.

  • Page 4: Safety

    2. Safety Sharp Measurement Pins: The measurement pins are very sharp as they are intended to penetrate through hard materials. Ensure that the pin cap is always covering the pins when not in use to avoid unintentional injury to the user or others. Meter Calibration: Meters are factory-calibrated prior to shipment.

    Info: The PX-30 comes with 3 material calibrations: Paper, Reference -Paper, and Baled Scrap, and though the EDGE™ app, users can remove any unwanted species. The PX-20 includes Paper only. Use: Select the Read menu. While the underline flashes, press the down button to enter the species/material selection field.

  • Page 9: Set Point

    If the meter is used on stock so thin that the full length of the pins are not entirely embedded in the thickness of the sample, the readings tend to indicate a lower than actual MC. This can be overcome by testing more than one sample in stacks. Use: Use the navigation buttons to move to the live reading area (entry will be confirmed when a live reading appears on screen).

  • Page 10: Material Temperature

    Info: The Set Point is the user-selectable moisture level at which the alarm will sound. This feature allows users to take readings without having to review each one individually, helping to quickly identify high moisture areas. Use: When active, press the left and right buttons to adjust the Set Point down or up.

  • Page 15 comparative tests, readings should be taken on samples considered to be at “safe” levels or in satisfactory condition. These readings are then used as the “standard” against which subsequent readings on the same material are evaluated. The “standard” for any given material is related to safe storability or any other property which is important for further production processing.
