Objects which, because of their size or shape, cannot be put on the scale, can be weighed by means of be­low-balance weighing.
Proceed as follows:
• Turn off the balance.
• Remove the weighing pan and the pan holder than turn the balance up side down.
• Push the metal-cover (1) on the floor of the balance to one side.
• Hang a small hook (available as an accessory, see chapter 6 "Accessories") into the aperture (3) of the now visible metal casting (2).
• Place the balance over an opening.
• Replace the pan holder and the weighing pan.
• Level the balance (see chapter 3.6 "Levelling")
• Switch on the balance.
• Hang the object to be weighed on the hook and carry out the weighing.
CAUTION
Take care that the hooks used for the below-balance weighing are stable enough to hold the goods which you wish to weigh.
NOTE
Take care that no dirt or moisture can get into the balance with the weighing pan removed. After completing the below-balance weighing, the opening in the floor of the balance must be closed again
(dust protection).

8.1 Representations and symbols
Important safety instructions are highlighted with the appropriate symbol:
8.2 Safety recommendations
• When using the balance in surroundings with increased safety requirements the corresponding regulations must be observed.
• The balance may only be used with the power adaptor supplied exclusively for use with this balance.
• Before plugging in the power adaptor, make sure that the operating voltage stated on the power adaptor agrees with the mains voltage. If not, please refer to the Customer Service.
• If the power adaptor or its cable is damaged, the balance must immediately be disconnected from the elec­tricity supply (pull out the power adaptor). The balance may only be operated with a power adaptor in per­fect condition.
• If there is any reason to believe that it is no longer possible to operate the balance without danger, the bal­ance must immediately be unplugged from the electricity supply (pull out power adaptor) and secured against inadvertent operation.
• In carrying out maintenance work, it is essential to heed the recommendations in chapter 22.4 "Cleaning".
• The balance must not be operated in an area subject to explosion risks.
• Take care when weighing liquids that no liquid is spilt into the inside of the balance or into connections on the rear of the equipment or the power adaptor. If liquid is spilt on the balance, the latter must immediately be unplugged from the mains electricity supply (pull out power adaptor). The balance may only be operated after it has first been re-checked by a Service technician.
• The operating instructions must be read by each operator of the balance and must be available at the work­place at all times.The balance may only be used for the weighing of solid-materials and of liquids filled into secure containers and for animal weighing and density determinations. The maximum allowable load of the balance must never be exceeded, otherwise the balance may be damaged.
• When using the balance in combination with other appliances, the current regulations for the safe use of the relevant attachments and their application in accordance with instructions must always be observed.
DANGER
Warning of a possible danger which can lead to death or to serious injuries.
CAUTION
Warning of a possibly dangerous situation which can lead to less severe injuries or damage.

9Set up
9.1 Unpacking the balance
The balances are delivered in an environmentally-friendly package, specifically developed for this precision instrument, which provides optimum protection for the balance during transportation.
In order to avoid damage, attention must be given to the following points when unpacking the balance:
• Unpack the balance carefully. It is a precision instrument.
• When outside temperatures are very low, the balance should first be stored for some hours in the un­opened transport package in a dry room at normal temperature, so that no condensation settles on the bal­ance when unpacking.
• Check the balance immediately after unpacking for externally visible damage. If you should find transport damage, please inform your Services representative immediately.
• If the balance is not to be used immediately after purchase but only at a later time, it should be stored in a dry place where fluctuations in temperature are as low as possible (see chapter 9.3 "Storage").
• Read through these operating instructions, even if you already have experience with balances, before you work with the balance and pay attention to the safety recommendations (see chapter 8 "Safety").
9.2 Transport and shipping
Your balance is a precision instrument. Treat it with care. Avoid shaking, severe impacts and vibration during the transportation. Take care that there are no signification temperature fluctuations during the transportation and that the bal-
ance does not become damp (condensation).
9.3 Storage
If you would like to take the balance out of service for an extended period, disconnect it from the electricity supply, clean it thoroughly (see chapter 22.4 "Cleaning") and store it in a place which meets the following conditions:
• No violent shaking, no vibrations
• No significant temperature fluctuations
• No direct solar radiation
•No moisture
NOTE
Retain the original packaging in order to avoid transportation damages when shipping or transporting the balance and to allow the balance to be stored in the best conditions if it is out of operation for an extended period.
NOTE
The balance should preferably be dispatched and transported in the original packaging to avoid transpor­tation damage.
NOTE
The balance should preferably be stored in the original packaging, since this provides optimum protection for the balance.
Page 15
9 Set up ■
13
9.4 Choosing a suitable location
The balance location must be chosen in such a way as to guarantee perfect operation of your balance, so that the allowable ambient conditions and prerequisites are met and maintained:
• Put the balance on a solid, firm and preferably vibration-proof, horizontal base
• Make sure that the balance cannot be shaken or knocked over
• Protect from direct solar radiation
• Avoid drafts and excessive temperature fluctuations
9.5 Connecting the balance to the mains
The following safety recommendations must be observed when connecting the balance to the mains:
9.6 Levelling
To function properly, the balance must be precisely horizontal. The balance is fitted with one spirit level and two adjustable feet for level-control, with the aid of which it
is possible to compensate for small height differences and/or unevennesses in the surface on which the bal­ance is standing.
The two screw feet must be adjusted so that the air bubble is precisely in the centre of the sight glass of the bubble level.
9.7 Calibration of the balance
Since the Earth's gravity is not the same everywhere, each balance must – in accordance with the underlying physical weighing principle – be adjusted to compensate for the gravity at each location. This adjustment process, known as “calibration”, must be carried out on initial installation and after each subsequent reloca­tion. In order to get exact measurements, it is recommended moreover, that the balance should also be cal­ibrated periodically.
NOTE
With difficult conditions (where the balance may be easily shaken or subject to vibration) the balance can nevertheless provide accurate results through suitable adjustment of the stability control (see chapter
10.3.5 "Weighing mode").
DANGER
The balance may only be operated with the power adaptor supplied. Check before connecting the power adaptor to the mains supply that the operating voltage stated on the
on the balance or on the power adaptor agrees with the local mains voltage. If the operating voltage is not the same as the mains voltage, the balance or the power adaptor must on
no account be connected to the mains supply. Contact the Customer Service.
Incorrect Correct
NOTE
In order to get exact measurements, the balance must again be carefully levelled after each relocation.
Page 16
■ 9 Set up
14
Calibration is effected in the configuration menu. Depending on the balance model, this may be done exter­nally, internally or automatically (see chapter 10.3.4 "Calibration functions" and see chapter 22.1 "Calibra­tion").
With the aid of the “Intelligent Calibration Mode” the balance can itself determine the size of the calibration weight, which enables an exact calibration with different size weights (in 10 g, 50 g, 100 g and 500 g steps, depending on implementation).
9.8 Dual Range and Floating Range balances
With the Dual Range balances, weighing is always first carried out in the fine range, which is 10 times more precise. When the fine range is exceeded the balance switches automatically into the coarse range.
The Floating Range balances have a fine range (10 times more precise), which moves over the entire weight range. By pressing the tare key «T» the fine range can be called up as often as required over the entire weight range.
9.9 Standardized balance
The standardized balances are provided with the EC/OIML certification or meet the local standardisation reg­ulations.
The balance range and certain functions of the weighing output differ from the standard program in the case of the standardized balances – in accordance with the EC/OIML provisions.
9.10 Switching on the balance
•Press «ON/OFF» to switch on the balance.
The balance carries out a diagnostic test in order to check the most important functions. After completion of the start-up process (approximately ten seconds) “Zero” appears in the display.
The balance is ready for operation and is in the Weighing mode.
9.11 Auto-Standby Mode
The balance is equipped with an Auto-Standby mode, which can be activated or deactivated in the config­uration menu.
If the Auto-Standby mode is activated, the balance automatically switches to Standby some time after the last weighing or key operation (current-saving function).
The delay before switching to Standby is defined in the configuration menu (see chapter 10.3.5 "Weighing mode").
• Press any button or put on a weight in order to switch the balance from the Standby mode back to the Weighing mode again.
NOTE
The balance must be calibrated on initial installation and after every relocation. If you work in accordance with “Good Laboratory Practice GLP” observe the prescribed intervals between
calibrations (adjustments).
NOTE
If a circle appears in the main-display of a standardized balance, the indicated value is unstandardised. In balances of class (1) the circle also stands for the warm-up phase. Your Customer Service will be happy to assist you at any time if you have any questions on the stand-
ardization of the balance or on working with standardized balances.

For calibration of the balance see chapter 9.7 "Calibration of the balance" and see chapter 22.1 "Calibra­tion". The setting depends on the balance model.
10.3.5 Weighing mode
With the aid of the Weighing mode functions, you may define the quality of the balance location (see chapter
9.4 "Choosing a suitable location"). With the aid of the „AUTO-STANDBY“ function, you can define the period of non-use before the balance au-
tomatically switches into the energy-saving mode.
„FLOATINGDISPLAY“
The value set for „FLOATINGDISPLAY“ defines the period after which each new measurement is displayed. For the definition of this period, the quality of the balance location is crucial. The stability control must also
set appropriately. Recommended values:
– Optimum balance location: „FLOATINGDISPLAY 0.08“ – Good balance location: „FLOATINGDISPLAY 0.16“ – Critical balance location: „FLOATINGDISPLAY 0.32“
„STABILITY“
The value set for the stability control depends on the quality of the balance location and must be correctly chosen in order to obtain optimum, reproducible results. Choose:
– Optimum balance location: „STABILITY LOW“ – Good balance location: „STABILITY MEDIUM“ – Critical balance location: „STABILITY HIGH“

„AUTO-STANDBY“
The Auto-Standby mode turns off the balance automatically, if:
• the balance is tared and has shown “Zero” for at least 5 minutes
• the balance has received no remote control command via the interface for at least 5 minutes,
• the automatic zero correction „AUTO-ZERO” is activated. It is possible to re-start the balance after it has been switched off by an automatic Auto-Standby:
• Briefly press any key
• Put a weight on the balance
• Make a remote control command via the interface
„AUTO-ZERO“
If the automatic zero correction „AUTO-ZERO” is activated, the balance always gives a stable zero (e.g. even with fluctuations in room temperature).
„ZERO-RANGE“
Defines the maximim weigth to performe a zero function instead of a normal tare when pressing «T» or sen- ding the remote command to tare. This value can be adjusted to make sure a small load is saved as tare and printout e.g. on a report as tare value.
10.3.6 Interface functions
The RS232/V24 interface on the device is matched to the interface of a peripheral device with the aid of the interface functions (see chapter 21 "Data transfer").

10.3.8 Anti-theft encoding
The balance can be protected against theft by using a freely selectable, four-digit numerical code:
• If the anti-theft code is deactivated, the instrument can be re-started and operated after a power outage without having to enter a code.
• If the anti-theft code is activated, the instrument requires the code to be input after each power outage.
• If the code is entered incorrectly, the instrument is locked.
• If the instrument is locked, it must first be disconnected from the power supply, then reconnected and unlocked by entering the correct code.
• After seven consecutive incorrect entries, the display reads „NO ACCESS, CALL SERVICE”. In this case only a service engineer can unlock the instrument again.
Procedure to activate the anti-theft encoding:
The procedure for changing the code is as follows:
NOTE
The anti-theft encoding is deactivated in the factory settings.
The preprogrammed code set at the factory is: 8 9 3 7 This code is the same in all balances. Therefore, for security reasons, enter your own code. Keep your own code in a safe place.

14.1.1Methods of determination
You can use the "DENSITY" workflow to determine the density of solids and liquids. You can choose between different methods of determination:
•"MODE LIQUID" :
Density of a liquid (only with density determination kit 350-8515)
• "MODE SOLID IN AIR" : Density of a solid
• "MODE SOLID POROUS" : Density of a porous solid
• "MODE SOLID ON BOTTOM" : Density of a solid with a vessel on the weighing pan
14.1.2Density index calculation
The density index indicates the percentage difference between two densities:
The two densities are used such that density_1 is always >= density_2.
Either two consecutive densities are compared, or the last density determined is compared with the input reference density.

15 Differential weighing ("DIFF.-WEIGHT")
15.1 Explanatory notes on differential weighing
In the application differential weighing, samples are investigated for weight changes, the results logged in a report and collated in statistics. In differential weighing the original weight of a sample is determined at the start of a measurement. Following the treatment of the sample, e.g. drying, ashing, vapor-depositing, coating, etc., the sample is re­weighed, and the balance determines the difference between the two measurements. Each sample can be re-weighed up to three times. There is a selection of different units available for the display of the results.
Up to 500 samples can be measured, divided into a maximum of 10 groups. Statistics are compiled for each individual group.
There are four semi-automatic measuring sequences available for recording the measurements:
– Individual measuring sequence
Record complete sample details with the tare weight, original weight and residual weight(s). Then move on to the next sample.
– Group 1 measuring sequence
Record the tare weight and original weight of all the samples in a group at the start. Then determine all the residual weights for a sample and, after that, measure the residual weights for the next sample.
– Group 2 measuring sequence
Record the tare weight and original weight of all the samples in a group at the start. Then determine the first residual weight for all the samples, followed by the second residual weight for all the samples, etc.
– Series measuring sequence
First of all enter the tare weights of all the samples in the group, then record the original weights of all the samples and, after that, re-weigh all the samples.
15.2 Selecting the differential weighing application
In order to activate the application menu, press the «MENU» key and select the "DIFF.-WEIGHT" application.
The submenus which are required for defining the differential weighing are now displayed in the "SETUP APPLICATION" menu.

Series
Navigation
The differential weighing program works with semiautomatic measurement recording. Once one value has been measured, the program automatically navigates to the next one.
The user can navigate between the measured values using the arrow keys , as shown by the arrows in the graphics. If a reading has been measured incorrectly, the user can navigate back to it with the arrow keys provided this navigation is possible (see the graphic for the set mode).
The tare weight, original weight and residual weight are recorded in consecutive order for each sample. Once the measurements for one sample have ended, the next one can be started.
The tare weight and original weight for each sample are recorded at the start. The residual weights are then measured for all the samples.
The tare weight and original weight for each sample are recorded at the start. Then determine the first residual weight for all the samples, followed by the second residual weight for all the samples, etc.
The tare weight is measured for each sample at the start. Then record the original weight for all the samples and, after that, re-weigh all the samples.

16 Minimum original weight ("MIN.-WEIGHT")
16.1 Explanatory notes on the minimum sample weight application, MSW
MSW application is a minimum original weight solution which enables you to fulfill QM guidelines, such as GLP, GMP or USP.
16.1.1 Minimum original weight and quality management
Only very small quantities are used in many applications and, thus, only a small part of the balance's weighing capacity is used. However, the lower the original weight, the greater the relative measuring uncertainty. What is the minimum original weight necessary to enable the quality management tolerance limits to be complied? The minimum original weight which is required is determined on the basis of the QM criteria and of the statistical data from repeated weighing procedures. If the weight is below the minimum original weight, a warning appears on the balance display warning you of this; these values are also marked in the printout.
–The requisite minimum original weights should be elicited on the basis of the QM specifications by means
of the statistical analysis of certain series of measurements. (The balance's own "STATISTIC" function could be used for this purpose, for example. It is used to perform and subsequently log the requisite series of measurements.)
– Once the minimum original weight(s) has/have been determined, it/they can be input into the balance.
Up to three tare ranges can be defined with the corresponding minimum original weights.
The balance's weighing modes, as well as measuring time and stability, are also fixed in such a way as to guarantee compliance with tolerances in future measurements.
Tare ranges, minimum original weights and weighing modes cannot be changed by the user.
– The values which are input can be logged by means of an application status print and could, along with
the report on the statistical measurement series, be used as a QM certificate. If work is performed on the basis of the minimum original weight application, this serves to ensure that the weighing results conform to the certificate specifications and, thus, to your QM guidelines.
16.2 Selecting the minimum original weight application
In order to activate the application menu, press the «MENU» key and select the "MIN.-WEIGHT" application.
The submenus which are required for defining the minimum original weight are now displayed in the "SETUP APPLICATION" menu.

If you now reset the display in a series of weighing procedures with identical or similar tare weights between weighing procedures and ensure that the same minimum original weight is set at all times, use the "ZERO KEY" «>0<» instead of the tare key.
16.5 Determining the minimum original weight periodically
The minimum original weight is dependent on the ambient conditions. Therefore, it must be determined on­site and must be reviewed periodically.
The following parameters influence the minimum original weight:
• Repeatability: The repeatability is determined by the standard deviation of the balance on-site. It is determined by the ambient conditions, the nature of the goods being weighed and the balance settings.
• Tare weight
• Relative uncertainty (U): The tolerable uncertainty is determined by the user or defined by standards.

• Extension factor (k) (generally 2 or 3): The extension factor determines the likelihood of occurrence. The factor is defined by the user or is defaulted.
The minimum original weight is calculated as follows:
Example of figures for the MSW in accordance with the USP:
If work is conducted in accordance with the USP (United States Pharmacopoeia), the following parameters are given:
• Repeatability: Standard deviation if the same weight is placed on ten times.
• Extension factor: k=3
• Rel. uncertainty:
U=0.1%
The repeatability of an XR125SM in the tare range between 0 and 35 g was determined as a standard deviation on site by placing a weight on ten times and measures 0.025 mg.
The minimum original weight is thus calculated as follows:
In compliance with USP24-NF19, the original weight on the XR125SM may not be less than a minimum of 75 mg.
Recommended procedure:
– Conduct the tests on-site and as close to the real situation as possible.
– Try to provide the best possible ambient conditions.
Ensure that these conditions do not deteriorate significantly afterwards in normal operation.
– First of all, configure the "FLOATINGDISPLAY" and "STABILITY" weighing modes (see chapter 16.3.2
"Non-variable menu settings").
– Define the due-date for the next check, "NEXT TEST", in accordance with your QM specifications.
– Define the extension factor and relative uncertainty in accordance with your QM specifications and
describe this under "Test parameters". The test parameters are merely for information purposes.
– Determine the minimum original weight(s) for your balance as follows:
Determining repeatabilities / Defining tare ranges:
First of all, test the behavior of the balance in different tare ranges: Divide the balance's weighing range into 10g intervals, for example, and measure the repeatability for each interval. Draw a graph of the entire weighing range by plotting all the results, joining them together and working

out the mean:
– On the basis of this graph it is relatively easy to define the max. 3 ranges with the corresponding
repeatabilities. (If you know which tare weights are typically used, you can optimize the tare ranges in terms of these typical weights.)
Measuring the repeatability (StdD) with the aid of "STATISTIC": Apply the relevant tare weight permanently to the balance and tare it. Conduct the measurement series with a net weight of approx. 1g:
– 1: + 1.00287 g Example of how the STATISTIC function is used.
2: + 1.00291 g

StdE % : 0.00 % Max : + 1.00293 g Min : + 1.00287 g
– Calculating the minimum original weight(s):
Now calculate the minimum original weights using the equation shown above, on the basis of the repeatabilities belonging to the tare ranges.
– Configure the balance with the determined values.

17.1 Introduction to the dynamic weighing application
The "DYN. WEIGHT" workflow supports accurate weighing on an unstable surface, e.g. on board ships. During the period of measurement defined by the user in the setup menu, the balance measures continuously, calculates the mean of the saved values at the end of the period of measurement and indicates the average measurement value which this yields.
17.2 Selecting the dynamic weighing application
In order to activate the application menu, press the «MENU» key and select the "DYN. WEIGHT" application.
The submenus which are required for defining the dynamic weighing are now displayed in the "SETUP APPLICATION" menu.

18 Pipette calibration ("PIPETTE")
18.1 Introduction to pipette calibration
Quality management systems require volumetric measuring equipment to be checked regularly. This application allows you to check pipettes of any make by means of a gravimetric method.
You require a thermometer and a barometer in order to conduct this. During the pipette test, the sample volume is always derived from the sample weight. The density of the test
liquid (distilled water) and the buoyancy are taken into account during conversion. The pipette application supports up to 20 pipettes. By simply selecting the pipette you require, its
specifications are loaded into the application. You can then commence the pipette test straight away. The pipette specification data must be defined once beforehand in accordance with the manufacturer's
details. You can change this at any time later on. If you wish to adjust the pipette, please consult the pipette manufacturer's instructions.
18.2 Selecting the pipette calibration application
In order to activate pipette calibration, press the «MENU» key and select the "PIPETTE" application.
18.3 Configuring the pipette calibration
In the "SETUP APPLICATION" menu, specify the measuring sequence and define the pipettes. The tolerances for inaccuracy and imprecision are manufacturer and model-specific. Refer to the pipette manufacturer's documentation for data.

Up to three test volumes can be selected per pipette. Pipettes with a variable volume are normally tested at 10%, 50% and 100% of the maximum volume.
"VOLUME"
Enter the test volume in [ml].
"INACCUR. <E>"
The permissible incorrectness is entered for each volume in terms of [%] of the test volume. The incorrectness describes the systematic error (setting range: (+/-) 0.1 - 9.9%).
"IMPREC. <STDE>"
The permissible imprecision (standard deviation) is entered for each volume in terms of [%] of the test volume. The imprecision describes the statistical error (setting range: 0.1 - 9.9%).
CYCLE TIME
The cycle time determines the duration of a single measurement (suck in liquid, discharge, wait for a stable weighing reading). The weighing reading is adopted at the end of the cycle time. This facilitates reproducible work. Short cycle times minimize evaporation losses; large volumes require longer cycle times (slow discharge of the pipette volume) (setting range: 0-120s).

19 Air buoyancy correction ("BEST")
19.1 Introduction to air buoyancy correction
The "BEST" (Buoyancy Error Suppression Technology) application can be used to correct errors which arise as a result of air buoyancy. Balances are adjusted with steel weights with a density of 8 g/cm
3
to prevent errors occurring at this density. As soon as goods of other densities are weighed, the air buoyancy causes an error which can be corrected by the factor K.
This correction is automatically conducted in the "BEST" application once the air and material density has been entered.
19.2 Selecting the air buoyancy correction application
In order to activate the application menu, press the «MENU» key and select the "BEST" application.
19.3 Configuring the air buoyancy correction
The "SETUP APPLICATION" menu now contains the settings for the air buoyancy correction.
19.4 Working with the air buoyancy correction
Press «F» briefly to go to the air buoyancy correction. When the air buoyancy correction starts, the user is prompted to confirm the air density.
Configuration of the function keys:

22.1 Calibration
The calibration of the balance is fixed in the Configuration menu (see chapter 9.7 "Calibration of the balance" and see chapter 10.3.4 "Calibration functions").
Possible types of calibration, depending on the model of balance:
• External calibration by means of ICM (Intelligent Calibration Mode)
• External calibration with freely selectable weight
• Internal calibration
• Automatic calibration
22.1.1 External calibration by means of ICM
Depending on the type of balance, calibration weights in steps of 10 g, 50 g, 100 g and 500 g can be used, where the calibration weight must correspond to the precision of the balance.
For an external calibration by means of ICM, „SET CALIBRATION MODE EXTERNAL“ must be selected in the Configuration menu (see chapter 10.3.4 "Calibration functions")
.
22.1.2 External calibration with freely selectable weight
For external calibration with user-definable weight, „SET CALIBRATION MODE EXT. -DEF.“ must be selected in the Configuration menu (see chapter 10.3.4 "Calibration functions").
Then, the effective value of the calibration weight (DEF. n.nnn g) must be entered with up to tenfold preci­sion compared with the balance.
NOTE
The calibration can be interrupted at any time by pressing «ON/OFF».

Then proceed as follows:
22.1.3 Internal calibration
For internal calibration with the built-in calibration weight „SET CALIBRATION MODE INTERNAL“ must be selected in the Configuration menu (see chapter 10.3.4 "Calibration functions").
Then proceed as follows:
• Switch to „WEIGHING“ with the Change key
•Press «T» until „CALIBRATION“ is shown.
• Calibration is finished after a certain period of time
22.1.4 Automatic calibration
For automatic calibration with the built-in calibration weight „SET CALIBRATION MODE AUTO“ must be se­lected in the Configuration menu (see chapter 10.3.4 "Calibration functions").
The balance now calibrates itself automatically every 24 hours and/or after each temperature change of 3 degrees Celsius, depending on the definition in the Configuration menu „SET CALIBRATION MODE AUTO“.
The time of the automatic calibration is as determined in the Configuration menu under „SET CALIBRATION AUTOCAL. -TIME n h“. (e.g. 6 h for 06.00 o'clock in the morning)
22.2 Automatic Repeatability Test (ART)
During the Automatic Repeatability Test, the internal weight is measured 10 times, and the standard devia­tion is calculated from this and logged.

NOTE
For automatic calibration by time and by time/temp. the date and time of the balance must first be cor­rectly set (see chapter 10.3.7 "Date and time.").
Calibration can also be effected manually at any time when auto-calibration is activated. Automatic calibration then takes place only if no weight has been placed on the pan for at least five min-
utes. It is recommended that the time for auto-calibration be set outside the normal business hours (for exam-
ple, in the early morning).

22.3 Software update
Our balances are instruments which are being continuously advanced and improved. For this reason, it is possible to update to the latest version of the instrument software via the internet.
In order to update your software, you need to download the Download Tool from the website and install it onto a PC with Windows.
The software for the balance can also be downloaded from the Downloads area on the website. This can then be loaded into the instrument with the aid of the download tool.
22.4 Cleaning
The balance must be treated carefully and cleaned regularly. It is a precision instrument.
Regularly dismantle the weighing pan and the weighing pan holder and remove any dirt or dust from under the weighing pan and on the balance housing with a soft brush or a soft, lint-free cloth, moistened with a mild soap solution.
The weighing pan and the holder can be cleaned under running water. Take care that both parts are com­pletely dry before they are re-installed on the balance.
The regular maintenance of the balance by your Service Representative will guarantee unlimited function and reliability over many years and will extend the lifespan of the balance.

DANGER
For maintenance work, the balance must be separated from the power supply (remove power adaptor plug from socket). Also ensure that the balance cannot be reconnected to the power supply during the work by a third party.
Take care during cleaning that no liquid penetrates into the appliance. If liquid is spilt on the balance, the latter must immediately be disconnected from the electricity supply. The balance must only be used again after it has first been checked by a Service Engineer.
The connections on the rear of the appliance and the power adaptor must not come into contact with liq­uids.
CAUTION
Never use solvents, acids, alkalis, paint thinners, scouring powders or other aggressive or corrosive chemicals for cleaning, since these substances attack the surfaces of the balance housing and can cause damage.
