RS-232 TRANSMISSION METHOD
This function allows the measurement data to be
sent to any terminal or serial port. The device uses
a Simplex asynchronous serial communication (can
be changed to Duplex if necessary) of the RS232
electrical interface. The data transmission is in ASCII
code. Each data set has 10 bits. Information about
the individual bits:

DEVICE USE
UNIT. Changing weighing units:
In order to change the weighing unit, press the UNIT
button, the unit symbol will change on the display.
TARE. Tare weight:
Place an empty container on the weighing pan.
When the reading is steady, press the TARE button
and the display will zero. The display will show:
• ZERO if the value is less than ± 5% of the scale;
• TARE if the value is more than ± 5% of the scale;
PCS. Piece counting
If required, place the container on the weighing pan
and press „TARE“. While the zero function is active,
press the PCS button. The „—SAP 10—“ message
will be displayed. Press the UNIT button to select
the sample size (10, 20, 50, 100, 200, 500, 1000
pieces). After selecting the number of samples, press
the TARE button to confirm. The display will show
„LOAD-C“. Place the previously selected number
of samples on the weighing pan. After the steady
reading has disappeared, the sampling procedure
is completed, and you can start using the piece
counting function.
NOTE: it is best to use more samples to make the
count more accurate.
PRINT. Printing function
Pressing the button during the weighing procedure
will send the weight data to the computer.
CALIBRATION
Press and hold the TARE button for 3 seconds, the
„LOAD-2“ message will be displayed. By using the
PCS key, you can select „LOAD-2“, „LOAD-3“ or
„LOAD-4“. There are two ways to calibrate:
• Constant load:
Press the TARE button again, a value will be
displayed, place an equivalent load on the
weighing pan. The display will show „ZERO“.
Remove the load and put on a weight
corresponding to the next value indicated. After
this operation the calibration is completed.
• Load selection:
Select „LOAD-1“ using the PCS key. Press the
TARE button. While the display is flashing, press
the „PCS“ button and enter the value. To change
the digit position, press the TARE button. After
moving to the last digit position, place the
selected load on the weighing pan. When the
reading stabilizes, the calibration procedure is
completed.

Bit No. 3 - 4: Measurement status
» OL - Overload
» UL - Negative
» ST - Stable
» US - Unstable.
•
Bit No. 5 - 12: The measurement value contained in 8
bits where one bit corresponds to the sign separating
decimal from integer values (here „.“); if the data does
not take up all 8 bits, a space will be used as the fill.
•
The „+“ or „-“ symbol is 1 bit (spaces are used instead
of the „+“ symbol).
•
Bit 13 - 16: The current weight unit contained in 4
bits.
•
If the unit does not take all the 4 bits in the weighing
mode or in the percentage mode, the empty fields
will be filled with spaces.
•
Bit 17 - 18: Movement to the beginning of the current
line and a new line are marked with „0DH“, „0AH“.

2.3. PERSONAL SAFETY
a) Do not use the device when tired, ill or under the
influence of alcohol, narcotics or medication which can
significantly impair the ability to operate the device.
b)
The device is not designed to be handled by persons

using the ON/OFF switch are hazardous, should not
be operated and must be repaired.
b) Disconnect the device from the power supply
before commencement of adjustment, cleaning and
maintenance. Such a preventive measure reduces
the risk of accidental activation.
c)
When not in use, store in a safe place, away from
children and people not familiar with the device who
have not read the user manual. The device may pose
a hazard in the hands of inexperienced users.
d) Keep the device in perfect technical condition.
Before each use check for general damage and
especially check for cracked parts or elements and
for any other conditions which may impact the safe
operation of the device. If damage is discovered,
hand over the device for repair before use.
e)
Keep the device out of the reach of children.
f)
Device repair or maintenance should be carried out

e)
In case of fire, use a powder or carbon dioxide
(CO
2
) fire extinguisher (one intended for use on live
electrical devices) to put it out.
f)
Regularly inspect the condition of the safety labels. If
the labels are illegible, they must be replaced.
g)
Please keep this manual available for future
reference. If this device is passed on to a third party,
