CAUTION Warning of a possible danger which may lead to minor injury or damage.
  • Page 12 If you spill any liquid onto the instrument, unplug it from the electrical supply immediately. Do not operate the moisture analyser again until you have had it checked by a Precisa service engineer. CAUTION Some of the parts, like the heating element and the viewing window, may become considerably hotter while it is in operation.

  • Page 13: Set Up

    (see chapter 3.2.2 "Storage"). • Read these Operating Instructions carefully before operating the balance, even if you have used Precisa equipment before and pay particular attention to the safety instructions (see chapter 2 "Safety").

  • Page 14: Transport, Storage

  • Page 18: Safety Measures

    ■ 3 Set up Safety measures The safety class 1 instrument, the moisture analyser, may only be plugged into a socket which has been installed in accordance with regulations and is fitted with a protective earth terminal. The safety effect may not be undone by using an extension lead without an earth wire.

  • Page 19: Weight Calibration

    3 Set up ■ Weight calibration Since the Earth's gravity is not the same everywhere, each balance must be adjusted to compensate for the gravity at each location, in accordance with the underlying physical weighing principle. This adjustment process, which is known as "calibration", must be carried out on initial installation and then each time the instrument is moved to another location.

  • Page 20: First Measurement

    ■ 4 First measurement First measurement Once the moisture analyser is successfully up and running, you can perform an initial measurement to familiarize yourself with the new instrument and to test it for any malfunctions.

  • Page 43: Determining Moisture Levels

    6 Determining moisture levels ■ Determining moisture levels The moisture analyser is used as a quick and reliable means of determining the moisture content in powders and liquids by the thermogravimetric process. Fundamental principles The term moisture does not just relate to water, it also encompasses all substances which evaporate when they are heated.

  • Page 44: Adjusting To The Existing Measuring Process

    ■ 6 Determining moisture levels 6.1.1 Adjusting to the existing measuring process The moisture analyser is frequently used in place of other drying techniques (like the drying oven) because it is easier to operate and offers shorter measuring times. Consequently, the conventional measuring process has to be adapted to the device so that comparable results can be achieved.

  • Page 45: Preventing Samples Being Encrusted

    6 Determining moisture levels ■ Solids: • Distribute powder samples evenly on the weighing pan. • Make course samples smaller using a mortar or grinder. Do not expose the sample to any heat while you are grinding it as this will lead to a loss of moisture.

  • Page 46: Setting Drying Parameters

    ■ 6 Determining moisture levels NOTE The additional solvent is taken into account in the measurement printout because all the interim values are calculated on the basis of the current weight value. However, it has no bearing on the drying result because the solvent has completely dried off.
