    Ambient conditions The DM 80-UMS digital pressure gauge is only intended for use in commercial workshops. It is not approved for ATEX areas and therefore must not be used in potentially explosive areas.

  • Page 6: Product Description

    2. Product description The DM 80-UMS is a digital pressure gauge with actual value display as well as min/max display and accuracy class 0.5 FSO. The MIN/MAX memory is permanently updated and overwritten. The sampling rate is 10 milliseconds (100 measurement values/second) for measuring dynamic pressure peaks. The integrated data logger saves the measured data.
  • Page 7 Item Designation Button Function The bar graph graphically depicts the maximum measuring span. The stored MAX value is displayed as a static, individual bar Bargraph ① (= drag pointer function). The display is updated at an interval of 10 milliseconds. (100 measurements / second) Actual value display, Displays the current pressure.
