2 Safety ■ Safety Representations and symbols Important safety-related instructions are highlighted visually at the description of what to do: DANGER Warning of a possible danger which may lead to death or to serious injury. 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.
(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").
■ 3 Set up Transport, storage 3.2.1 Transport and shipping Your moisture analyser is a precision instrument. Treat it with care. Avoid shaking it or subjecting it to any heavy jolts or vibrations during transport. Avoid serious temperature fluctuations and getting the instrument damp (condensation) during transport.
3 Set up ■ Inspection and assembly The moisture analyser does not come fully assembled. Once you have unpacked all the parts, check that the delivery is complete and assemble the individual components in the order indicated below.

• You can now place an aluminium pan (4) on the pan support. NOTE All the parts must be attached together without exerting undue force. Do not apply any force. If you have any problems, the Precisa customer service will be happy to help. Choosing a suitable location...
3 Set up ■ Connecting it to the mains Follow safety instructions when connecting the instrument to the mains: DANGER The instrument may only be operated using the original mains cord supplied. If the mains cord supplied is not long enough, only use an extension cord fitted with a protective earth conductor.
■ 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.
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.
■ 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. Switch the instrument on using the «ON/OFF» key. The instrument performs a self-diagnostics test to check the main functions.

The structure of the application menu is dynamic and can be defined in the configuration menu (see chapter 5.3.4 "Configuring the application menu"). If a menu option is disabled in the configuration menu, it is not contained in the current application menu.
The XM66 moisture analyser features two freely definable methods, as per the XM 60 or XM 60-HR, and three additional fixed methods (cannot be changed), which have been specially created for the moisture determination of sewage sludge.

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.
■ 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.
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.
■ 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.
Page 53
The drying temperature is predefined by the user. During the first three minutes of drying, the target temperature is exceeded by 40%. (In the XM 60, XM 60-HR the time is selectable between 0.1 - 99.9 min) Once this time has elapsed, the temperature is adjusted down to the target temperature.
Page 54
■ 6 Determining moisture levels This program is used for samples with a very high moisture content. T [ C] 140 % 100 % t [s] 180 s Soft drying The drying temperature is predefined by the user. The end temperature is started up gently with a low heat output.
6 Determining moisture levels ■ 6.3.2 Temperature This function key is used to start the drying temperature input. The drying temperature can be entered in 1°C increments from 30°C ... 230°C. After 10 minutes temperatures higher than 200°C are automatically adjusted down to 200°C over the course of the next 20 minutes.
This function key is used to start the definition of the switch-off criteria for the measurement. XM 60, XM 60-HR Two freely definable stop modes are available according to the "digit per time" resp. "% per time" principle. There is also the automatic stop mode "ADAPTSTOP".

■ 6 Determining moisture levels on the basis of the drying progress. Statistics (XM 60, XM 60-HR) All results are automatically taken into the statisical evaluation. – Insure that there is no drying taking place, i.e. that the instrument is in weighing mode.
ASH RESIDUE The determination method of ash residue varies between the models XM 60, XM 60-HR and XM 66. When determining the ash residue, the desiccated sample is taken as the entry value. This sample is re- duced to ash in an external furnace and then re-weighed in the moi- sture analyser.
7 Ash residue program ■ Ash residue XM 60, XM 60-HR The XM 60 and XM 60-HR can only store one initial sample weight. There are no options to set parameters for ash residue determination. Ash residue: – Ensure that no moisture analysis is taking place, i.e. that the instrument is in weighing mode.
■ 7 Ash residue program NOTE Tare the moisture analyser with an empty pan before starting the ash residue process. Ash residue XM 66 The moisture analyser XM66 can store up to four initial sample weights ("MEMORY CHOICE ON"), which are not deleted after deter- mination of the ash residue.

8 Data transfer ■ Data transfer The moisture analyser is equipped with an RS232/V24 interface for data transfers to peripheral instruments. Before the data transfer, the RS232 interface must be matched with the one in the peripheral instrument in the instrument's configuration menu (see chapter 5.3.10 "Interface functions").
