REQUIREMENTS FOR AN OPTIMAL INSTALLATION
To obtain the maximum performance and the best results, we recommend
installing the balance according to the following requirements:
• Install it on a firm and stable surface.
• Place it on a stable base free of vibrations.
• Don´t expose it to direct sunlight.
• Don´t submit it to atmospheres with corrosive gases.
• Keep it in an environment free of dust and dirt.
• Work at temperatures between 15º and 30º C.
• Use the balance in environments with humidity lower than 95% HR.
• Keep the balance away from equipment that produces magnetic or
acoustic interferences.
• Calibrate it in its definitive place of use and check it regularly with a
calibration weight (optional), if necessary, recalibrate it.
UNPACKING
Unpack the balance carefully. Inside the carton you will find the following
components:
• This operation manual (please, read it before using the balance).
• A balance Series AH.
9
• A stainless steel pan.
• An AC/Adaptor of 12 V / 800 mA; don´t use any other adaptor, it could
damage the balance.
• A CD-ROM with USB adaptor.
• A USB cable.
• Five pieces of windshield.
VERY IMPORTANT: Keep the original package. It could be useful in the future
in transportin the balance.
10
INSTALLATION
1. Remove the package from the carton.
2. Remove the pan from the cardboard.
3. Remove the AC/Adaptor (it is inside a white box).
4. Take out the balance from its protection and place it on its definitive place
of use, which should be a flat, non-metallic, most stable and rigid surface.
5. Put the stainless steel pan on the pan support.
6. Level the balance by turning the four adjustable feet until the bubble
level located on left frontal side remains in the centre of the circle.
7. Connect the AC/Adaptor to the balance´s connector and then to an outlet
of 220/240 V. 50 Hz.
8. Calibrate the balance with a proper calibration weight. This action is very
important in order to obtain accurate weighing results.
9. For maximum accuracy, it is necessary to keep the balance connected
for about 60 minutes before using it. However, the balance can also be
used immediately with good results.

WEIGHT UNIT SELECTION
Press the key to select the weight units, the display will view the options.
There are 8 weight units available.
RESET TO ZERO
If the zero value varies during the weighing, press the
key, the display
will show zero again.
TARE
This function allows calculating the net weight of a product.
With display showing “zero”, place a container on the pan, then press the
key, the balance will subtract the container´s weight, put the product
into the container and then read the product´s weight on the display (net
weight).
To return to normal weighing model, remove the container and press the
key.
OVERLOAD MESSAGE
If an object is placed on the pan and its weight exceeds the maximal capacity
of the balance, the display will show the message “-----OL-----”, at the same
time, the balance will beep. Remove the object; otherwise it may damage the
mechanism of the balance.
14
PIECES COUNTING FUNCTION
The pieces counting function is used to count the number of pieces deposited
on the pan.
1. Place a container on the pan and press the
key.
2. Insert a certain number of pieces (10, 20, 50 or 100) into the container.
This number of pieces is the initial sample, the higher number grants
more accuracy in final counting.
3. Press the
key, select the desired sample number using the , ,
, or keys. To confirm the selected value, press the key.
4. The balance will accept the sample and after a few minutes will indicate
the pieces counting mode.
5. The display will show the number of pieces placed on the pan, add the
rest of pieces to obtain the total of pieces.
6. To count other pieces of a different weight unit, repeat the procedure.
7. To return to normal weighing mode, press the
key until the sign
grams “g” appears on the right side.
PERCENTAGES FUNCTION (%)
1. Once selected the percentage mode by pressing the key, use the
keys or , to choose between 100.0% or 100.00%.
2. Place the product, considered as 100%, on the pan and press the
key. The symbol “Modo” will flash for a few seconds and then the balance
will beep indicating the procedure is finished.
15
From this moment, the balance is ready to use the percentage function. When
the sample value is less than 0.2d, the display shows “---or---%”. It means
that the sample is too small, therefore, will need to add bigger samples.
Note: To exit from pieces-counting or percentages function, press the
key to return to normal weighing mode.
To return to pieces-counting or percentages function, press the
key. The
balance will automatically memorize the previous data, so you can continue
using both functions.
The data memory will be deleted automatically when you switch from one
mode to the other.
