  • Page 4: Safety Precautions

    2. Safety Precautions U.S. Solid Moisture Analyzer qualifies as state-of-the-art technology and complies with all recognized safety rules. Improper use or handling, however, can result in damage and/or injury. Follow the precautions below to ensure safe and trouble-free operation of your moisture analyzer.
  • Page 5 • Avoid allowing the analyzer to get wet. It is not a water-resistant structure. Any leakage of liquid into the analyzer may cause damage to the analyzer or an electric shock to the user. • Use a power source (voltage, frequency, outlet type) adapted to the specification of the analyzer.

  • Page 6: Cautions

    • For substances that produce corrosive vapors when heated (e.g. acids), work with small amounts of samples as the vapor may condense on cooler housing parts and cause corrosion. 2.3 Cautions • Operate the Analyzer on a stable, rigid and flat table. •...

    3. Confirm by pressing the “CONFIRM” button, the drying mode flashes. 5.1.2 Drying Mode setting Press the “UP” or “DOWN” to select the required drying mode and confirm by pressing “CONFIRM”. 1. Standard drying mode This mode is the default setting and is suitable for most samples. The heating temperature can be set, the sample is heated to the set temperature during the test, and the temperature is maintained until the test ends automatically.

  • Page 19: Ending Mode Setting

    2. Fast drying mode This mode is suitable for samples with high moisture content. The heating temperature can be set, and the initial temperature will exceed the set value, and will later drop to the set temperature and remain until the test ends automatically.
  • Page 20 1. Automatic ending mode The test will automatically stop at a certain point in time (when the moisture content does not change within 45 seconds) in the automatic stop mode. This mode takes effect after 15 seconds of heating. After the test is completed, the display shows the sample moisture content, heating time and current temperature.

  • Page 21: Calibration
