5.1 Adjustment/Test
Introduction for adjustment and tests
This section applies to the configuration of the balance for carrying out adjustments and tests.
§ The balance is assembled and installed as stated in the operating instructions.
§ The balance is leveled.
1 Connect the printer to printout settings or reports.
2 Activate the printer as an output device in the peripheral device settings.
Principles for carrying out adjustments and tests
Balances play a decisive role in research, development, quality assurance and production. Weighing errors
cost time and money and non-compliance with legal requirements can be detrimental to health. Good
Weighing Practice™ (GWP®) is the science based global weighing standard for the efficient life cycle
management of weighing systems. The risk-based approach allows you to improve control of your whole
measuring process, which in turn helps to avoid costly out of specification results. Our Feasible Cost
Savings Optimized routine testing based on your risk management ensures consistently good quality in
critical applications. Additionally, a sound testing scheme saves costs by eliminating unnecessary tests in
lower risk processes.
Test Manager was specially developed, as part of our balance firmware, to simplify routine tests. In
combination with GWP® Verification, efficient balance testing is ensured and specific audit requirements
can be fulfilled more easily.

Test Manager
Test Manager is a collection of security functions for the balance. These individually programmable
functions help to maintain measuring accuracy via e.g. routine testing of the balance with external test
weights. By providing active support with respect to test requests and predefined guided sequences will
ensure that outstanding tests are not forgotten and complex tasks such as repeatability tests can be carried
out easily.
Additional functions were developed to prevent measuring errors. These are, e.g. temperature sensors that
can register possible temperature changes in the measuring cell and initiate adjustment by using internal
weights which facilitate and maintain consistent accuracy.
The flexibility and customization of the test manager results in user guidance and appropriate messages,
while performing specific operations, followed by complete records and documentation via printout or in
conjunction with PC software.
The configuration process
In order to prepare the balance for a routine test and adjustment, a straightforward 3-stage process is
required:
1 Register the test weights.
ð Information relating to all test weights is stored in a balance database.
2 Define the test sequence.
ð Describes the type of test (method) and the test weight and tolerance to be carried out.
3 Carry out the test sequence.
ð The task defines when and how the test sequence must be started and carried out.
Documentation and storage
To ensure the traceability of adjustments and tests, it is important to print the settings and periodically the
results of the test history.
The results are stored in the test history up to a maximum of 120 entries. When this limit is reached, the
oldest results are overwritten.
Each time the test sequence is changed, the version number is increased and displayed in the right top
corner of the display. It is recommended to print and file each new version in a folder.
A complete list of individual settings can be printed by pressing the [

5.1.2.1.3 RPT1 - repeatability test with tare weight
Navigation: [
The RPT1 method calculates the mean and standard deviation (Symbol s) of a series of measurements with
two test weights in order to determine the repeatability. In contrast to the RP1 method, a second test weight
is used to simulate the use of a tare container.
The method uses two test tolerances (method tolerances), s T1 and s T2, which are applied to the test
sequence result. They work exactly the same as the weight tolerances T1 and T2.

Navigation: [
[SERVICE]
The SERVICE method is more a reminder than a method. It is normally set to perform regular checks of
various data (dates) in the background. It is used e.g. as a reminder for the next service date or MinWeigh
date. The date is checked on a regular basis and a message appears when the defined task is due. The
SERVICE method can also be used as early pre-warning.
The SERVICE method can also only be used for the display of Preparation Instructions. For example, the
user is requested to level the balance on a daily basis. In this special case, the Preparation Instructions
must be set in the test sequence setting to Standard. Ensure that no elements are selected in the method
status.
Note
To enable this test sequence to be ended without user actions, Preparation Instructions must be set in the
test sequence to None.

but is not accessible in the menu, please contact your METTLER TOLEDO representative.
MinWeigh
The MinWeigh function ensures that the weighing results are within defined tolerances appropriate to the
requirements of your quality assurance system.
The service engineer will determine the required minimum weights based on your QA requirements and
subsequently load these values into the balance. Up to 3 tare weights can be defined with the
corresponding minimum weights. The service engineer will set the weighing parameters to the values
required for the maintenance of tolerances.
See Weighing parameters [}49].
Note
After programming the balance, the service engineer will issue a certificate. This records the measurements
and tolerances as well as corresponding tare and minimum weights for weighing. These settings cannot be
changed by the user as long as the MinWeigh function is activated.

6.2.3 Working with identifications
Identifications are descriptive texts for individual weighing processes that allow perfect assignment of
weighing objects to specific customer orders. The identifications are also printed on the protocols (or
transferred to a connected computer).
The 3 identifications are designated by default with [ID1], [ID2], [ID3] and [ID4]. These designations can
be replaced with other titles to suit the particular application (max. 20 characters). The selected
designations (e.g. customer for the [ID1], order for the [ID2] and batch for the [ID3]) are subsequently
available under the [ID] function key.
Note
If the IDs are deactivated, the function key is grayed and cannot be actuated. In this case, the IDs must first
be activated before they can be used.
See Definition of identifications [}70].
When working with identifications, it is recommended to also activate the respective information fields. The
information fields show the designations entered for the identifications.
See Selecting information fields [}62].
If the weighing protocol is defined in such a way that the identifications are also printed, the defined ID
designations, e.g. [Customer] and the entered text, e.g. METTLER TOLEDO are printed out.

6.2.4 Working with the "MinWeigh" function
The MinWeigh function ensures that the weighing results are within defined tolerances appropriate to the
requirements of your quality assurance system. This function must be activated and programmed by a
service engineer.
It also recommended to activate the three information fields MinWeigh, RefTare and Tare.
Note
If several reference tare weights (and the associated minimum weights) were programmed by the service
engineer, the required minimum weight automatically changes appropriate to the applied tare weight.
The weighing result can be printed with the [

6.3 Balance adjustment and testing
] to tare the
Navigation: [
Like any precision instrument, the balance must be adjusted at regular intervals. The balance offers
extensive options for adjustment and testing.
Deviations must be able to be identified at an early stage and process tolerances checked. The risk can be
minimized by regular testing.
The adjustment is intended for adjusting the sensitivity of the balance. For this purpose, at least one
reference weight is placed on the weighing pan either manually or motorized. This is weighed and the
indicated weight is stored. The sensitivity of the balance is subsequently corrected by the required amount.
The test is intended for testing the sensitivity of the balance.
See Settings for adjustments and tests [}35].
The balance is set to automatic adjustment with FACT at the factory. FACT adjusts the balance fully
automatically based on predefined criteria. Manual adjustments and/or tests can be carried out as required
with the internal or an external weight.
If a printer is connected to the balance, the adjustments can be printed out according to user-specific
settings.
See Protocol – Definition of adjustment and test reports [}49].

tolerance range but greater than the plausibility limit cannot be entered in the statistics. If necessary, change
the plausibility limit for the weight values.
Note
The function keys for entering the nominal weight and the tolerance range are disabled if values are already

shown in the example printout.
Important information for the interpretation of recorded results
The x and s values are calculated results that are shown with higher resolution than the individual
measured values. The significance of the last decimal place cannot be assured with a relatively small
measurement series (fewer than 10 or so measured values) with small weight differences.

Calculation of mean value and standard deviation
Notation
= Individual measured value of a series of measured values
= Mean value and standard deviation of these measured values
The mean value is given by:
(1)
The commonly used formula for the calculation of the standard deviation
(2)
(2) not suitable for numerical calculation, since in measurements where deviations between single values
are very small, the square of the difference (between the single value and mean value) can lead to
cancellation. In addition, when using this formula, each single measured value must be stored before the
standard deviation can be finally determined.
The following formula is mathematically equivalent, but much more stable numerically. It can be derived by
appropriate transformation from (1) and (2):
For the calculation of the mean value and standard deviation, only ,
and
need to be stored for the
use of this formula.
Standard deviation
The numerical stability can be further improved by measured value scaling.
With
whereby
(depending on the application) is either the first measured value of a series of
measurements or the nominal value of a series of measurements, the following is obtained:
Mean value
The mean value is calculated accordingly:
Relative standard deviation
The relative standard deviation can be calculated using the formula:
percent
Number of digits in the results
The mean and standard deviation are always displayed and printed with one decimal place more than the
corresponding single measured values. To be noted for interpretation of the results is that this additional
decimal place has no significance for small series of measurements (less than about 10 measured
values).
Statistics Application94Precision Balances
Page 95
This applies similarly to percentages (e.g. relative standard deviation), which always has two decimal
places (e.g. 13.45 percent). The significance of the decimal places depends similarly on the magnitude of
the original values!
