Precautions
The scale was built in accordance with the European Directives on electromagnetic compatibility.
Please read the following instructions carefully before operating the scale.
•Do not use in high hazard areas;
•If you are installing the balance in environments that require higher safety standards, please comply with the
provisions specified in national legislation;
•Make sure that the voltage provided by the power supply is in line with the AC adapter label;
•The only way to completely turn off the balance is to unplug the power adapter;
•Use only original accessories that are compatible with the instrument in question;
•Protect the power supply from contact with liquids;
•When cleaning the scale, make sure that no liquid is entering the electrical compartment.
•Contact your authorized service department for problems.
•The scale should be used in closed and dry environments.
Before starting
Shipment and storage
Do not expose the balance to:
•Temperatures above 40 ° C and below 4 ° C;
•Airflow;
•High humidity environments;
•Shock and vibrations;
Check equipment and accessories
After opening the balance box, carefully check that there is no damage caused by the transport.
In the event of damage contact the dealer or the transport company immediately.
Store the original packaging.
If the instrument is shipped to service center without original packaging, the warranty will expire.

Placement and installation
Right placement
The correct positioning of the balance greatly influences the
accuracy of the measurements.
It is important to ensure a stable and anti-vibration support.
To avoid
•Direct light
•Temperature fluctuations
•Dust
•Conditioners and fans
Antitheft
The balance is equipped with an anti-theft system, designed to
discourage a possible attempted theft.
The cable and the padlock are not supplied with the scale.
Levelling the balance
The BL 224 has a level control and adjustable feet to compensate for
minor irregularities in the weighing surface.
The scale is exactly horizontal when the air bubble is in the middle of
the target.
Before turning on the balance, level it by rotating the adjustable feet so
that the level air bubble is in the center of the ring.
Make sure all the feet are securely fixed on the bench.
Connection of peripheral electronic devices
Turn off the balance before connecting or disconnecting a device
(printer, PC).
Before performing the first measurement, the weighing sensor
temperature must align with the ambient temperature in order to
obtain the best results.
Warm up: 60 min.

Calibration
To get the best possible results, Balance must be calibrated in the place of use.
Calibration is necessary:
•At the first use;
•at regular intervals over time;
•After a change of placement.
For homologated scales, the calibration can be deactivated during installation, as required by national regulations.
Is possible to stop the calibration at any time by pressing <ESC> key.
Display shows “Abort”.
External calibration
•Switch on and wait for the warm-up time
•Make sure there is no weight on the plate
•Close the sliding windows

•Keep pressed <CAL> key for 3 seconds = “Cal Et”
•The display shows the weight to use to calibrate.
•Place the weight for calibration at the center of the
weighing pan.
The weight must be in the appropriate accuracy class.
•Wait until display shows “CAL donE”.
The balance returns to measurement mode, ready for sample
weighing.

recalled in the measurement mode.
Is possible to choose from the following preset units:
Stability filter
It is possible to set the stability filter to adjust the balance to external conditions, in order to obtain the best possible
result.
Stability filter value:
•1= Very good external conditions;
Very fast, but very sensitive to external influences (vibration, etc.)
•2= “Normal” conditions (default settings)
•3= Unstable external conditions
The balance is slower but less sensitive to external influences
•4= Extremely unstable external conditions;
Slow but less sensitive to external influences

Calibration settings
Is possible to choose:
•CAL Et = External Calibration, using a certified external sample mass.
•CAL Int = Internal calibration, using the sample mass inside the balance

Calibration test
Is possible to enable or disable the Calibration Test function.
If enabled, the calibration test will be performed both for internal calibration
and for external calibration.
Auto Zero Tracking
This menu item allows you to enable or disable the Auto Zero tracking function.
Auto Zero tracking: If the scale detects small variations from 0,0000, for
example due to powder particles, it corrects it automatically and returns to
0,0000.

Update)
6. After placing the exact quantity of pieces corresponding to
the selected reference number inside the container, press
the <TARE>
As soon as the measure is stable, the average weight of each
piece will be calculated, and the quantity will be shown.
7. You can now add the remaining pieces to count.
Note:
Is possible to switch between the amount display and the weight display at any time by pressing the <UNIT>
key.
It is advisable to use the highest possible reference quantity, so that the scale can have a very large
reference from which to calculate the average.
The pieces you want to count must have the same weight.
The settings remain in memory until a new reference weight is determined.

Differential weighing
The differential weighing is used to determine the weight variation of one or more
samples.
The first step is to determine the initial weight of the sample.
Following operations such as scratching, centrifuging, filtering, vaporization, etc. The
sample is weighed again, and the difference is determined with respect to the initial
value.
100L (Loss)
The moisture content is displayed as a percentage of the initial sample.
The humidity value is shown with a negative sign, and with a unit of measure 100L%
example: -11.35 100.00L%
100R (residue)
The dry content content is displayed as a percentage of the initial sample.
The dry residue value is shown with a positive sign, and with a unit of measurement
100R
example: +8.25 100.00R%
AtroM (Humidity content)
Atro's moisture content is the percentage value of moisture relative to the dry residue.
The ATRO humidity value is shown with negative sign, and with AtroM unit of
measure%
example: -255.33AtroM%%
AtroD (Dry content)
Atro's moisture content is the percentage value of moisture relative to the dry residue.
The ATRO humidity value is shown with negative sign and with AtroM unit of
measure%.
example; 312.56 AtroD%%
