Getting to know your Moisture Analyzer – Section 1

1 Getting to know your Moisture Analyzer

Please read through this Section carefully, it contains important information for safe and economical operation of your Moisture Analyzer.

1.1 Introduction

Thank you for deciding to purchase a Halogen Moisture Analyzer from METTLER TOLEDO – you have made a wise choice. Your Moisture Analyzer is fast and reliable. It offers a high level of operating convenience and useful functions to facilitate determination of the moisture content of your samples.

Behind your instrument stands METTLER TOLEDO, a leading manufacturer of not only balances and scales for the lab and production, but also analytical measuring instruments. A customer service network covering the entire globe with well trained personnel is at your service at all times, whether you are choosing accessories or require guidance for a specific application to ensure optimum utilization of your instrument.

To ensure you make full use of the possibilities offered by your Moisture Analyzer, we advise you to read through these operating instructions very carefully.

1.2 What is the Halogen Moisture Analyzer used for?

Your Halogen Moisture Analyzer is used for determining the moisture content of almost any substance. The instrument works on the thermogravimetric principle: At the start of the measurement the Moisture Analyzer determines the weight of the sample, the sample is then quickly heated by the integral halogen heating module and the moisture vaporizes. During the drying process the instrument continually measures the weight of the sample and displays the reduction in moisture. Once drying has been completed, the moisture or solids content of your sample is displayed as the final result.

Of decisive importance in practice is the rate of heating. In comparison with conventional infrared heating or the drying oven method, for example, the halogen heating module of your instrument needs a shorter time to reach its maximum heating power. It also allows use of high temperatures, an additional factor in shortening the drying time. Uniform heating of the sample material ensures good repeatability of the drying results and makes it possible to use a smaller amount of sample.

All parameters of a measurement (drying temperature, drying time, etc.) can be preselected. But your Moisture Analyzer offers many other possibilities. To avoid exceeding the scope of this introduction, only a few of these are listed here:

– 10 different methods can be individually optimized to suit your samples, and easily activated at a keystroke.

– You can choose between various types of result display at any time.

– Your settings and measurement results can be recorded, stored and protected.

– One comment line can be entered for each measurement.

– Thanks to the built-in rechargeable battery your valuable data remain stored even on power failure.

Section 1 – Getting to know your Moisture Analyzer

This wealth of functions notwithstanding, your Moisture Analyzer is very simple to operate. The status display (User guide) guides you step by step through the measurement cycle. You always know which particular stage in a measurement is currently being executed by the instrument and the next operating step. To exclude faulty handling in routine work, the keypad can be locked to prevent access to all but the elementary functions. The motorized, automatic sample chamber offers the operating convenience you are familiar with from compact disk (CD) players. Moreover, the motorized sample chamber opens up new possibilities for automatic operation of the instrument (loading by means of robots) when used with the LocalCAN universal interface installed as standard.

Besides operating convenience, however, the quality of the measurement results is still what counts above all. The built-in weighing cell meets the high standard which has made METTLER TOLEDO the worldwide market leader in the field of high-resolution precision balances.

A brief word regarding standards, directives and procedures for quality assurance. The Moisture Analyzer conforms with all common standards and directives. It supports stipulations, work techniques and result records as demanded by all international quality assurance systems, e.g. GLP (Good Laboratory Practice), GMP (Good Manufacturing Practice). The instrument has a CE declaration of conformity and METTLER TOLEDO as the manufacturer has been awarded ISO 9001 and ISO 14001 certification. This provides you with the assurance that your capital investment is protected in the long term by a high product quality and a comprehensive service package (repairs, maintenance, servicing, calibration service).

You will find further information in the following Sections of these operating instructions. Please read through this information carefully to ensure you can use your instrument in an optimum and safe manner.

1.3 Safety has priority

Your Moisture Analyzer employs state of the art technology and meets the latest demands regarding instrument safety. This notwithstanding, improper operation can endanger personnel and cause damage to tangibles. For safe and dependable operation, please comply with the following instructions:

– The Moisture Analyzer is used for determining the moisture in samples. Please use the

instrument exclusively for this purpose. Any other type of use can endanger personnel and damage the instrument or other tangibles.

– The Moisture Analyzer must not be operated in a hazardous environment and only under the

ambient conditions specified in these instructions.

– The Moisture Analyzer may be operated only by trained personnel who are familiar with the

properties of the samples used and with the handling of the instrument.

– Your Moisture Analyzer is supplied with a 3-pin power cable with an equipment grounding

conductor. Only extension cables which meet the relevant standards and also have an equipment grounding conductor may be used. Intentional disconnection of the equipment grounding conductor is prohibited.

Getting to know your Moisture Analyzer – Section 1

The Halogen Moisture Analyzer works with heat!

– Ensure sufficient free space around the instrument to avoid heat accumulation and

overheating (approx. 1 m free space above the instrument).

– The vent over the sample must never be covered, plugged, taped over or tampered with in

any other way.

– Do not place any combustible materials on, under or next to the instrument when it is

connected to the power supply, since the area around the heating module becomes hot.

– Exercise caution when removing the sample. The sample itself, the automatic sample

chamber and any sample vessels used may still be very hot.

– During operation, you should never open the heating module as the ring-shaped heating

module or its protective glass can reach 400 °C! If you have to open the heating module on occasion, disconnect the instrument from the power supply and wait until the heating module has cooled down completely.

–No modifications must be made within the heating module. It is particularly dangerous to bend

any components or remove them, or to make any other changes.

Certain samples require special care!

With certain types of samples, there is a possibility of danger to personnel or damage to tangibles through:

Fire or explosion:

– Flammable or explosive substances

– Substances containing solvents

– Substances which evolve flammable or explosive gases or vapors when heated.

With such samples, work at a drying temperature that is low enough to prevent the formation of flames or an explosion and wear protective goggles. Should there be any uncertainty regarding the flammability of a sample, always work with a small amounts of sample (max. 1 gram). In such cases, never leave the instrument unattended! In cases of doubt, perform a careful risk analysis.

Poisoning, burning:

– Substances which contain toxic or caustic components. Such substances may be dried only

in a fume cupboard.

Corrosion:

– Substances which evolve corrosive vapors when heated (e.g. acids). In the case of such

substances, we advise you to work with small amounts of sample as the vapor can condense on cooler housing parts and cause corrosion (if necessary, the heating module can be changed very easily by the user, see Section 7.6).

Please note that the user always takes responsibility and assumes liability for damage caused by use of the types of samples mentioned above!

– Never make any modifications or constructional alterations to the instrument and use only

original spare parts and optional equipment from METTLER TOLEDO.

– Your Moisture Analyzer is a rugged precision instrument – but you should still treat it carefully;

it will then thank you with many years of trouble-free operation.

Section 2 – Your first measurement in next to no time

2.2 Selecting the location

Your Moisture Analyzer is a precision instrument. An optimum location guarantees accuracy and dependability:

– Firm, horizontal location as free from vibrations as possible

– Avoid direct sunlight

– No excessive temperature fluctuations

– No powerful drafts

– Surroundings as free from dust as possible

– Adequate free space at the front for opening the sample chamber and

sufficient clearance around the instrument to allow warm air to dissipate.

– Sufficient distance from heat-sensitive materials in the vicinity of the

instrument.

2.3 Setting up, leveling and connecting to power supply

Exact horizontal positioning and stable installation are prerequisites for repeatable results. To compensate small irregularities or inclinations (±2%) at the location, the instrument can be leveled.

For exact horizontal positioning, the Moisture Analyzer has a level indicator

(level) and 3 leveling screws. As soon as the air bubble is precisely in the

middle of the cross hairs, the instrument is exactly horizontal. To level it, proceed as follows:

Position your Moisture Analyzer at the selected location.

Screw in the right front leveling screw completely (it is not needed for leveling). The instrument is now standing on the front left, nonadjustable foot, as well as on the two rear leveling screws.

Turn the two rear leveling screws until the air bubble is located in the middle of the level indicator. The arrows and the leveling screw designations (R = right rear leveling screw, L = left rear leveling screw) on the cross hairs will facilitate the setting:

Your first measurement in next to no time – Section 2

indicates the right leveling screw must be turned in a clockwise direction.

Unscrew the front right leveling screw until it contacts the support and the

If the air bubble is located at the bottom left, for instance, the inscription

instrument is resting firmly on all 4 feet. Ensure that the air bubble remains in the center of the level indicator.

Note: The instrument should be releveled each time its location is changed.

Connect the instrument to the power supply.

Warning: If the power cable supplied is not long enough, use only a 3-pin extension cable with equipment grounding conductor!

For technical reasons, the halogen heating module is designed specifically for a particular line voltage (110 V AC or 230 V AC). A heating module is installed in the factory that is matched to the particular line voltage of the country of destination. If you are not sure whether the heating module built into your instrument is suitable for your local line voltage, check the voltage data in the interior of the heating module before you connect the Moisture Analyzer to the power supply!

Connection to a line voltage that is too high can lead to blowing of the fuses, whereas a supply voltage that is too low will prolong the drying process.

On/Off

Ensure that the transport arrestment is removed. Instructions on how to remove the transport arrestment can be found on the leaflet enclosed with the package.

Switch the instrument on with the «On/Off» key.

Note: When putting into operation for the first time, leave the instrument connected to the power supply for at least 5 hours to allow the built-in battery to charge up! If the instrument is later disconnected from the power supply for several months, the battery will become discharged. This leads to data loss. To recharge the battery, leave the instrument connected to the power supply for at least 5 hours.

Following your first practical work with the Moisture Analyzer, in this Section you will find important information on how to obtain optimum results. You will discover what parameters influence the measurement process and how you can match the instrument optimally to your particular measurement task.

3.1 Measurement principle of the Halogen Moisture Analyzer

Your instrument performs measurements based on the thermogravimetric principle, i.e. the moisture is determined from the weight loss of a sample dried by heating.

In principle, your instrument thus comprises two instruments: a precision

120

balance and a heating module. In contrast to other thermogravimetric methods (drying oven, infrared, microwave), the Halogen Moisture Analyzer operates with a halogen heating module. This ensures fast heating of the sample and thus guarantees rapid availability of the measurement results.

Irrespective of the measurement method, the quality of the measurement results stands or falls by the preparation of the sample and a correct choice of the important measurement parameters:

– Sample size

– Drying temperature

–Switchoff mode

– Drying time

Inappropriate setting of these parameters can cause the results to be incorrect or misleading. For this reason, check that the results for each type of sample are what might reasonably be expected.

You will find detailed information on the relationships between these parameters in the application brochure for moisture determination (see Section 9.3), enclosed to your instrument.

In practice, however, not only the quality of the measurement results, but also the speed of the measurement process is important. Thanks to its drying principle (with the heat generated by a halogen radiator), the Halogen Moisture Analyzer is very fast. You can increase the speed even further through optimum setting of the instrument.

The optimum drying temperature and the drying time are dependent on the nature and size of the sample and on the desired accuracy of the measurement results. These can be determined only by experiment. The Halogen Moisture Analyzer supports you in this task: It offers automatic performance and result recording of test measurements.

How to obtain the best results – Section 3

3.2 Notes on adjustment of the balance and the heating module

You should adjust your Moisture Analyzer regularly (e.g. every six months) if this is stipulated by your quality assurance system (e.g. GLP, GMP, ISO 9001).

The balance and the integral heating module in your instrument can be adjusted using the appropriate accessories (see Section 9.8). The heating module and balance can also be tested (to check the adjustment). The operator can define a test weight or the test temperature, together with permissible tolerances for this test. A test report is printed out showing the test result as “Passed” or “Failed” (see Section 6.3 and 6.5).

By adjusting the heating module you can ensure comparability with results from other instruments of the same design. This is done by using an appropriate thermometer, which is provided in the form of a temperature adjustment set with calibration certificate (see Section 9.8). This adjustment set comprises a black plate with a thermometer, which allows a reproducible adjustment of the heating module.

A Moisture Analyzer is typically used in place of or in addition to the oven method. In an oven heat energy is transferred by the flow of air, which establishes an equilibrium between the sample temperature and the ambient temperature. This is not the case in a Moisture Analyzer. The actual sample temperature primarily depends on the specific absorption properties of the sample (“dark” samples absorb more heat), which can change during the measurement process. temperature inside the sample. The heat output is therefore not dependent on the true sample temperature but instead is regulated by a temperature sensor underneath the halogen heating module.

For the reasons explained above, the temperature setting on the instrument will therefore by deviate to the true sample temperature. By regularly adjusting the heating module, you will ensure a consistent and reproducible heat output for the entire lifetime of your instrument.

Note: METTLER TOLEDO offers an adjustment service – please contact your local dealer.

– If you also use your instrument as a high precision lab balance, you should adjust the balance at regular intervals.

– If you replace the heating module, you must adjust it using the temperature adjustment set, which is available

as an accessory.

The procedure for adjusting the balance and heating module is described in Section 6.

There can also be differences between the temperature at the surface of the sample and the

Section 3 – How to obtain the best results

3.3 Optimum sample preparation

Preparation of the sample is decisive for the speed of the measurement process and the quality of the measurement results.

Please note the following basic rules for the preparation of your sample:

The amount of sample you select should be as small as possible and only as large as necessary

Excessive amounts of sample require more time for drying and thus prolong the measurement process. If the amount of sample is too small, the measurement result may possibly not be representative. The following always holds: The greater the inhomogeneity of the sample, the larger the amount of sample needed to obtain a repeatable result (please see also the list in Section 9.1).

Distribute the sample evenly over the sample pan

You thus increase the surface area of the sample and facilitate heat absorption. The base of the pan should be evenly covered.

With liquid, fat-containing, melting and highly reflecting samples, you should cover the sample with the glass fiber filter available as optional equipment (HA-F1 214464, see Section 9.8). This also applies to samples which form a skin on their surface when heated. The glass fiber filter ensures even and rapid heat distribution and prevents the formation of a skin impervious to moisture on the sample surface.

3.4 Further information on moisture determination

You will find further information on the moisture determination, the importance of the parameters and the preparation of the samples in the Application Brochure “Methods of moisture content determination” dealing with moisture determination (see Section 9.3). Useful tips and a variety of example methods (comparison between Halogen Moisture Analyzer results and the oven method) can be downloaded from www.mt.com/moisture.

If you require information on specific applications, your METTLER TOLEDO dealer will be pleased to help you.

Moisture determination applications must be optimized and validated by the user according to local regulations. Application-specific data provided by METTLER TOLEDO is intended for guidance only.

4 Practical application of your Moisture Analyzer

In this Section we introduce you to the wide range of setting possibilities of your Moisture Analyzer and offer information and tips for optimum setting of the parameters.

4.1 Operating principles

You already performed your first measurement in Section 2. This measurement was carried out using the factory settings. However, your instrument offers a number of setting possibilities to match the measurement process to your specific requirements. For instance, you can preselect the drying temperature, the type of result display and many other parameters.

Settings are made using the function keys. These keys are right at the top of the keypad, directly below the display. The setting you select appears in the display directly above the associated key.

125

You will learn the available setting possibilities and the function keys in detail in the following Sections. Further, you will also discover how to set the drying temperature and the drying time and how to work with the weighing-in aid. Finally, you will perform a complete measurement with the specific settings for your sample.

Numeric entries:

With some settings (e.g. the drying temperature), numeric entries are required. There are two different ways of entering numerical values:

You can change the flashing displayed value with the «Scroll up» or «Scroll down» key or ...

... You can enter the new value with the «0…9» key.

0...9

As soon as you have entered the desired value, press the «Accept entry» key. The value will be stored.

Section 4 – Practical application of your Moisture Analyzer

Preliminary information on the methods:

All settings for a sample which you will learn in the following Sections can be collected in a so-called “Method”. You have 10 methods freely available thus giving you the possibility of defining a method for a particular sample and recalling it at any time. This eases the work load considerably as each time you switch to a different type of sample there is no need to repeat all the parameter settings. The methods are retained when the instrument is switched off. You will find information on the compilation and use of methods in Section 5.

4.2 Selecting the drying program

This function key offers you two different drying programs for optimum matching of the drying characteristics to the sample used.

Each time this key is pressed, the next program appears. After the fourth and last program, the first reappears in the display. As soon as you have selected the desired program, the setting is active and you do not have to confirm or store it.

Standard drying

This drying program is set in the factory and is suitable for most samples. The sample is heated to the drying temperature (set temperature) and held constant at this temperature.

Rapid drying This program is primarily suitable for samples with a moisture content over 30%. Following the start, the selected temperature is exceeded by 40% for

3 minutes to compensate the cooling due to vaporization and accelerate the drying process. The drying temperature is then lowered to the set value and maintained. You will find details on how to enter the drying temperature in the Section 4.3.

4.3 Setting the drying temperature

After pressing this key you can enter the drying temperature (set temperature).

The type of entry depends on the selected drying program (see Section 4.2). If you have selected one of the programs “Standard drying” or “Rapid drying”, you need enter only the drying temperature.

Press the «Accept entry» key.

Note: The admissible input range for temperatures is 40°C–200 °C.

Several mutually independent systems prevent the instrument overheating:

– At temperatures above 160 °C a time limit becomes active. The higher the

temperature, the shorter the time until the instrument starts to lower the temperature (envelope curve, see illustration opposite).

–A temperature switch independent of the normal black temperature sensor

over the sample (see Section 7.1) is triggered when it detects exceptionally high temperatures. This situation could arise, for example, if the sample begins to burn or the temperature calibration is defective. If this happens, the heating module is tripped out by a mechanical switch, and the instrument cannot be restarted. Please refer to Section 8.3 for troubleshooting.

When working with temperatures over 180 °C we recommend that you always wait 2 - 3 minutes between individual measurements, in order to ensure good reproducibility of the readings.

Note: A measurement cannot be started until the drying temperature is higher than the temperature in the measuring room.

You can check the

current temperature by pressing the «Tare (zero)» key. This avoids a false start (Error 10, Section 8.2).

Section 4 – Practical application of your Moisture Analyzer

4.4 Selecting the switch-off criterion

This function key offers you different switch-off criteria. A switch-off criterion defines when the instrument should end the drying. Switch-off criteria save you having to keep checking your watch and stopping the drying manually.

The following settings can be selected for the switch-off criterion:

–“Weight loss per unit of time” (5 settings)

– “Free switch-off criterion” (if activated in the Methods menu,

Section 5.4)

–“Manual switch-off”

– “Timed switch-off”

– “Test measurement” for determination of the suitable switch-off criterion

Weight loss per unit of time

This switch-off criterion is based on a weight loss per unit of time. As soon as the mean weight loss is less that a preset value during a specified time, the instrument considers drying as complete and automatically discontinues the measurement process. During the drying, the time display shows you how long the measurement process has been in progress. The switch-off criterion is inactive during the first 30 sec. You will find additional information in Section 9.4.

The following 5 settings are available:

This setting is suitable for samples which dry very quickly (surface moisture) or for (relatively inaccurate) fast measurements to determine a trend.

This setting is suitable for quick drying samples.

This is the factory setting. It is suitable for most types of samples.

This setting is suitable for samples which dry moderately quickly.

This setting is suitable for samples which dry very slowly (trapped moisture, skin formation).

Note: If you do not know the behavior of a sample, perform a test measurement to determine the suitable switch-off criterion. The procedure is described later in this section under the title “Test measurement”.

Practical application of your Moisture Analyzer – Section 4

Free switch-off criterion

This setting possibility is available only if you have activated it in the Methods menu (Section 5.4). There is one free switch-off criterion available for each method. The free switch-off criterion is based on a user-defined mean weight loss per unit of time.

You will find information on the activation and definition of the individual switch-off criterion in Sections 5.5 and 9.4.

Manual

With this switch-off criterion the measurement process continues until you stop it with the «Stop» key.

The time shown in the display tells you how long the current measurement has been in progress.

Timed switch-off

With this switch-off criterion the measurement lasts until the preset drying time has elapsed (the time display provides you with continuous information on the drying time).

If you select this criterion, you must then enter the desired drying time as follows:

Press the «Drying time» key.

⁄30

Enter the desired drying time.

Press the «Accept entry» key.

During the drying, the current measured value is continuously displayed in percent.

Comment on the ATRO display mode

If the current measured value in the ATRO display mode is greater or less than the predefined limit value (i.e. greater than 999.99 %AD or less than –999.99 %AM), a warning beep sounds and the instrument automatically switches the display mode (from %AM to %MC and from %AD to %DC). A display in the ATRO mode is no longer possible in this case, even if you have started your drying operation in the %MC, %DC or “g” (grams) display mode.

Section 4 – Practical application of your Moisture Analyzer

4.6 Defining the print interval

One point before we start: This setting possibility is available only if the built-in printer is activated in the menu

(see Section 6.15).

The print interval determines the printout frequency of the intermediate results of an ongoing measurement.

The following settings are available under this function key:

Printout at intervals

These 6 settings allow printout of the intermediate results at fixed, preset intervals. You can thus trace the drying process using the printed record. The following print intervals are available:

– Printout every 5 seconds

– Printout every 10 seconds

– Printout every 30 seconds (factory setting)

– Printout every minute

– Printout every 2 minutes

– Printout every 10 minutes

Manual printout

With this setting there is no automatic printout. However, you can print out the intermediate results at any time with the «Print» key.

Practical application of your Moisture Analyzer – Section 4

4.7 Working with the weighing-in aid

The weighing-in aid can be defined for each method and facilitates weighing in of the sample to a preset weight value (target value).This is particularly useful if you require all the samples you wish to process to have same weight in order to improve the repeatability of the measurement results. In addition, the weighing-in aid can be configured so that the drying process cannot be started if the weight of sample is outside the set tolerance. You are therefore compelled to weigh in the correct quantity of sample (“Weighing-in aid active”).

Target weight

lower weight limit upper weight limit

The weighing-in aid in the bottom right corner of the display comprises two opposite facing bars and triangles with a minus or plus symbol.

The weighing-in aid is available only if it has been activated. If the minus or plus symbol is visible after taring, the weighing-in aid is activated.

Underweight

WGªBAÈ OFF

WGªBAÈ PAS

WGªBAÈ ACT

Overweight

If you want to switch on the weighing-in aid, press the «Target weight (Weighing-in aid)».

In the factory the weighing-in aid is switched off (“OFF”).

You can use the «Scroll up» and «Scroll down» keys to select either the “Weighing-in aid passive” or “Weighing-in aid aktive” setting.

If the “Weighing-in aid passive” setting is selected, the weighing-in aid is switched on and a target weight can be defined. With this setting the drying process can be started even if the sample weight lies outside the set limits. These are defined by the target weight and the sample weight tolerance as a % of the target weight (see below).

With the weighing-in aid set at “Weighing-in aid active” the drying process cannot be started if the sample weight is outside the set limits. You are therefore compelled to weigh in the correct quantity of sample, and are prevented from inadvertently starting the drying process with the wrong sample weight.

After selecting the desired mode for the weighing-in aid, confirm your selection by pressing the «Accept entry» key.

TAR‚ “500

Enter the desired target weight (0,100 g to 80,000 g) (Factory setting:

5 Methods facilitate your work

Methods simplify and accelerate your daily work. In this Section you will learn how you compile, print out and change methods and how to use them. You will also become acquainted with the journal function and the statistics. You will find an overview diagram of all menu options in Section 5.4.

5.1 What is a method?

Perhaps you remember: In Section 4 you became acquainted with all the parameters and setting possibilities you can use to match your Moisture Analyzer to a particular measurement task. If you have to change samples frequently during your work, the methods save you having to reenter the parameters and preclude wrong settings. Methods thus make it easier for you to switch between different types of samples.

A method contains all settings for a particular sample. It can be recalled at

Methods

a keystroke and your instrument immediately operates with the corresponding settings. You have 10 methods freely available.

Methods

Margarine 1

Drying prog.: Standard drying

Drying temp.: 70 °C

Switchoff criterion:

Drying time: --------

Display mode result: MC (moisture content)

Print interval: 30 sec.

Target weight: 2.500 g

Loss < 1 mg/50 Sec.

The following parameters, which you have already learned in Section 4, form part of a method:

– Drying program

– Drying temperature

–Switch-off criterion

– Drying time (depends on switch-off criterion)

– Display mode

– Print interval

– Target weight for weighing-in aid

– Settings in the Method menu (Section 5.4)

Work with methods is divided into two stages: in the setting stage you define the parameters of the method and name the method. In the utilization stage you perform routine measurements with different samples. When switching from one sample to the next, you do not have to change any settings, you need simply select the method suitable for the sample. You will find information on how to use and set up of methods in the following Sections.

Section 5 – Methods facilitate your work

5.2 Recalling a method

7 Servicing and replacing individual parts

In this Section you will learn how to keep your Moisture Analyzer in good condition and how to replace expendable parts. You also find information on how to check the printer and change the printer paper and ribbon.

7.1 Cleaning

To obtain precise measurement results, we advise you to clean the temperature sensor and the protective glass of the heating modules at regular intervals. Please note the following directions for cleaning your instrument:

Disconnect the instrument from the power supply before cleaning.

Open the automatic sample chamber by pulling it out.

Remove the draft shield element and the sample pan holder before cleaning.

Use a lint-free cloth for cleaning.

Clean the exterior of the instrument and the drying compartment with a mild cleaning agent. Although the housing is extremely rugged and resistant to solvents, never use abrasive cleaning agents or solvents!

Ensure that no liquid enters the interior of the instrument.

To clean the temperature sensor and the protective glass of the heating module, you should first open the heating module as described in Section 7.6.

Carefully remove any deposits from the black temperature sensor.

Servicing and replacing individual parts – Section 7

To clean the protective glass of the heating module, dismantle the heating module (see Section 7.6), place it on a flat work surface and clean the protective glass with a commercial glass cleaner.

The air inlet of the fan is located at the rear of the instrument and its exterior should be cleaned from time to time to free it from any dust deposits.

After the temperature sensor and/or the protective glass have been cleaned, we recommend adjusting the heating module (Section 6.4).

7.2 Changing the printer paper and ribbon

Apart from the need to replace the printer paper and ribbon on occasion , the built-in printer requires no maintenance.

Changing the printer paper

The printer paper is changed as follows:

Open the cover of the built-in printer.

7.3 Replacing the power line fuses

If the display of your instrument remains “dark” after switching on, in all probability the power line fuses of the instrument are blown.

To change the fuses, proceed as follows:

Disconnect the instrument from the power supply.

The two power line fuses (for neutral and phase) are located at the rear of the instrument. Turn the two fuse holders with a screwdriver to the left and pull the fuse holders out of the instrument.

Check the condition of both fuses. Replace blown fuses by those of the same type with the same rated value (5 x 20 mm, T6, 3H 250 V).

Servicing and replacing individual parts – Section 7

The use of fuses of a different type or with different values as well as the bridging of fuses is not allowed and can hazard your safety and lead to instrument damage!

7.4 Printer test

Your instrument has a function to check the proper functioning of the built-in printer.

Ensure that the instrument is switched off.

Press and hold the «Paper feed» key while simultaneously switching the

On/Off

instrument on with the «On/Off» key. The printer prints out its complete character set.

To stop the test, switch the instrument off with the «On/Off» key.

7.5 Installing the built-in printer

If your instrument is not already fitted with a built-in printer, you can order a printer as an option and retrofit it at any time. You can also change the built-in printer yourself without any problems should this be necessary. The procedure for installing the built-in printer is described in the 11780558 you received with the printer.

7.6 Dismantling and replacing the heating module

If a fault arises, the complete heating module can be replaced. We also advise you to open or dismantle the heating module to clean the protective glass of the heating module (see Section 7.1).

Disconnect the instrument from the power supply and be sure to allow the heating module to cool down for 10 minutes before you start the work!

The heating module is released by withdrawing the automatic sample chamber 2-3 cm.

Section 7 – Servicing and replacing individual parts

Swing the heating module upward.

Disengage the hinge of the heating module by turning the two yellow levers 90° forward.

Remove the heating module (pull forward).

Install the (new or cleaned) heating module in the instrument and lock the hinge with the two yellow levers.

After a heating modules has been cleaned or replaced, we recommend readjusting the heating module of your Halogen Moisture Analyzer (Section 6.4).

Defective parts must be disposed of in accordance with applicable customer and national regulations.

If problems arise on occasion – Section 8

8 If problems arise on occasion

In this Section you will learn how errors can appear during operation of your Moisture Analyzer and how you can rectify these errors.

8.1 Notes on the error messages

Your instrument distinguishes between the three different types of errors explained below.

Input errors (key not active or can not be pressed in current operating status) are reported by your instrument with a short audio signal (if activated in the menu) without an error message in the display.

An application error occurs when the instrument can not perform a

ERROÈ 3

procedure or a corrective action is necessary as the limits of a value range have been violated or because a general operating error exists. Application errors are reported by your instrument with an audio signal. Further, the message “ERROR” appears in the display followed by the error number. You will find a list of all application errors in the next Section.

8.3 What if...?

… the display remains “dark” after switching on?

– no line voltage – power cable not connected – blown power line fuses – instrument faulty

Ensure that the instrument is connected to the power supply and that power supply is actually supplied. Check the power line fuses of the instrument and replace if necessary (see Section 7.3). If the instrument still refuses to function, contact your METTLER TOLEDO dealer.

… after switching on “0.000” flashes in the display?

The sample pan holder is not installed. Install the sample pan holder.

… the function symbols disappear from the display after a certain time

You have deactivated the symbols in the menu (see Section 6.14).

… the symbol of the stability detector is continuously lit up immediately after the start?

As soon as the symbol of the stability detector fades, the weighing result is stable and is accepted as a “wet weight”. If the symbol does not fade, your instrument is probably at an unsuitable location (vibrations, shocks, powerful drafts, etc.). Seek a more suitable location. Samples containing readily volatile substances may never reach stability owing to continuous evaporation. In this case, you must select manual operation for the automatic sample chamber (see Section 6.11).

… the built-in printer does not print?

Ensure that the printer is activated in the menu (see Section 6.15) and that the ribbon and paper are correctly installed. If the printer still refuses to print, perform a printer test (see Section 7.4). If the test is unsuccessful, contact your METTLER TOLEDO dealer.

… no drying time can be entered?

Entry of the drying time is possible only if you have selected the switch-off criterion “Timed switch-off”, with all other switch-off criteria this input possibility is not available (see Section 4.4). If you attempt to enter a drying time, the instrument reports “Error: 7” (see Section 8.2).

If problems arise on occasion – Section 8

… certain keys are inactive?

You have protected the parameters (switch-off criterion, print interval, etc.) in the menu against change (see Section

6.13). If you attempt to change a parameter, the instrument reports “Error: 6” (see Section 8.2).

… an error message appears when I press certain keys?

You have entered an illegal value, see Error messages (see Section 8.2)

… the measurement takes too long?

You have selected an unsuitable switch-off criterion. The suitable switch-off criterion is simple to determine by a test measurement. You will find information on how to perform a test measurement in Sections 4.4 and 4.11.

An excessive amount of sample can also be the cause of slow drying, likewise samples which tend to form a skin which hinders vaporization.

Perform experiment at higher temperature.

… the weighing-in aid is not visible?

The weighing-in aid is available only if you have activated (see Section 4.7).

… the automatic sample chamber does not close after pressing «Start»?

You have selected the manual operating mode in the menu (see Section 6.11).

… no methods are available?

You have deactivated the method option in the menu (see Section 6.16).

… the instrument does not heat following the start?

The dryer unit is overheated and the thermal overload protection has responded. The instrument is equipped with thermal overload protection (bimetallic sensor) which switches off the heating tube if overheating occurs. If this happens, the device must be reset. To do this, proceed as follows:

Disconnect the instrument from the power supply and be sure to allow the heating module to cool down for 10 minutes before you start the work.

The heating module is released by withdrawing the automatic sample chamber 2-3 cm.

Swing the heating module upward.

Section 8 – If problems arise on occasion

The thermal overload protection is reset by pressing the rear part of the white temperature switch.

The Analyzer can be restarted after closing the cover and connecting the instrument to the power supply.

Note: If this is not possible, there may be a fault (e.g. a faulty halogen heating module). In such a case, contact your METTLER TOLEDO dealer.

After the temperature switch is reset or a heating module replaced (Section

7.6) we recommend that you readjust the heating module of your Halogen Moisture Analyzer (Section 6.4).

… the measurement results are not repeatable?

– The samples are not homogeneous, i.e. they have different compositions. The more inhomogeneous a sample,

the larger the amount of sample needed to obtain a repeatable result.

– You have selected a drying time that is too short. Extend the drying time or select a suitable switch-off criterion

“Weight loss per unit of time”.

– The sample does not become completely dry (e.g. owing to skin formation). Dry the sample with the aid of glass

fiber filters (Section 3.3).

– You have selected a temperature that is too high and the sample has oxidized. Lower the drying temperature.

– The sample boils and the splashed drops continuously change the weight. Lower the drying temperature.

– Insufficient heating power as the protective glass is dirty. Clean the protective glass (Section 7.1).

– The temperature sensor is contaminated or faulty. Clean the temperature sensor (see Section 7.1) or have it

replaced by a service engineer.

– The support on which the instrument is standing is not sufficiently stable. Use a stable support.

– The instrument is not stable on its 4 feet.

– The surroundings are very unstable (vibrations etc.).

9 Further useful information

9.1 Notes on interpretation of the measurement results and the ideal sample weight

The accuracy of the measurement results depends on the wet weight and the original moisture of the sample. The relative accuracy of the measurement result improves with increasing wet weight. While the moisture of the sample is fixed, the weight of the sample can frequently be determined by the user. However, with increasing weight the drying process is lengthened. We thus advise you to select the weight of your sample to obtain the repeatability you require. You can use the following table to determine the ideal weight for your sample. The table does not include the scatter due to the sample and its preparation.

An example will suffice: A result with a repeatability of ±0.1% is expected. As the following table shows, your sample should have a minimum weight of 2 grams.

Repeatability of the result Minimum sample weight

±0.02 % 10 g ±0.05 % 4 g ±0.1 % 2 g ±0.2 % 1 g

9.2 LocalCAN universal interface

Your Moisture Analyzer is fitted with a modern LocalCAN universal interface. This universal interface allows your instrument to interchange data with a computer or a control system. METTLER TOLEDO LC-P43 and LC-P45 printers can also be operated via this interface. The content and format of the printouts are the same as those produced by the optional built-in printer HA-P43.

Devices (e.g. a computer) with an RS232 serial interface (with a DB9 or DB25 connector of the type usually found with PCs and laptops/notebooks) can be attached with the optional interface cables (LC-RS9 or LC-RS25, see Section 9.8).

For interface commands please refer to the “Reference Manual METTLER TOLEDO Standard Interface Command Set” 11780559, available from your METTLER TOLEDO dealer or download from the Internet (www.mt.com/

9.3 Application brochure

The application brochure for moisture determination from METTLER TOLEDO (order number: 11795011) contains a great deal of useful information for optimum utilization of your Moisture Analyzer. To order your personal copy, please contact your METTLER TOLEDO dealer.

Example methods and applications can be found at www.mt.com/moisture.

Moisture determination applications must be optimized and validated by the user according to local regulations. Application-specific data provided by METTLER TOLEDO is intended for guidance only.

9.4 Switch-off criterion “Weight loss per unit of time”

With the switch-off criterion “Weight loss per unit of time”, drying is automatically ended as soon as the mean weight loss (∆ g in mg) per unit of time (∆ t in seconds) drops below a preset value. 5 levels are preprogrammed in the factory each with a fixed weight loss per unit of time. Further, a “Free switch-off criterion” allows you to define the weight loss per unit of time yourself.

The following applies to the individually selectable levels:

∆ g in mg ∆ t in seconds

Switch-off criterion 1 1 mg 10 seconds

Switch-off criterion 2 1 mg 20 seconds

Switch-off criterion 3 1 mg 50 seconds

Switch-off criterion 4 1 mg 90 seconds

Switch-off criterion 5 1 mg 140 seconds

Switch-off criterion “F” (free) 1 mg to 10 mg 5 seconds to 3 minutes
