1. Introduction
Balance meter SE-12 is suitable for connecting platform with weight sensors and
performs all basic balance functions. Moreover, it is possible to perform data exchange
between SE-12 module and computer through the multi-station S485. If the module is
equipped with auxiliary S232C ports, it is also possible to read bar codes with the
handheld scanner and printing weight slips or self-adhesive labels. The module is
delivered separately or as part of ready balance (according to order).
2. Certificates
SE-12 meters have the test certificate no. PL CB 1, issued by Central Office Of
Measures in Warsaw (Notified Unit No. 1440).
Meters SE-01/N/18 and SE-01/N/25 have IP65 protection grade, confirmed by test
performed in esearch Laboratory of Electrotechnical Institute, accredited by PCA.
Meter can be used for constructing balance according to standard PN-EN 45501
Specification for metrological aspects of non-automatic weighing instruments, issued in
December 1999, harmonized with the 90/384/EEC council directive, changed by
93/68/EEC council directive).
Balances classification (PKWiU code) 29.24.23.
3. Balance keys and indicators

8. General operation principles
1. Platform with weight sensors should be located on flat, horizontal foundation, in place
not subjected to mechanical vibrations and strong air movements.
2. Devices turning on sequence: turn on computer, software, balance meter power supply.
It causes autotests performing and (after balance stabilization) displaying zero
indication.
3. Apart from connecting to the computer, the module allows for weighing and tare setting.
Tare setting is performed by pressing "T/
ON
" key. If the package tare is entered with
alphanumeric keyboard, using "T/
ON
" key is not necessary.
4. To facilitate the weight control on the pan and avoid the range exceeding, the load
indicator is located on the right side of display, scaled in 0÷100%.
5. The weighing result should be read during the " " indicator lighting, which indicates the
result stabilization.

6. Instead of negative indications 4 dashes are displayed: „ ---- ”. If that mesage is
displayed with unloaded platform, press "→0←" or "T/
ON
" key.
7. When there is no weighing, but the balance should be ready for operation, it may be
switched off by "" key. It causes the balance reading system deactivation end entering
the standby mode. The modul turning on is performed by pressing "T/
ON
" key. After the
autotests it is immediately ready for operation with full precision.
8. Weighed mass should be placed in the pan centre.
5. Do not overload the platform over 20% of maximum load.
6. Protect the module and platform from dust, aggressive dusts and liquids. For cleaning
purposes use water and dry it.
9. Data exchange with computer
If there is software activated in the computer, all module functions, besides displaying of
current indications and special functions, are controlled by the computer. Module
operator should read the messages from the computer, displayed on the module display,
and adapt his actions to them.
After the balance turning on with empty platform, indications display (upper) shows
zero indication. Three lines of text display (lower) shows computer information.
In the fourth line over F1, F2, …, F5 keys the messages indicating functions currently
realized by keys are displayed.
For example:
Then the dialogue between module operator and computer software begins, which has
various forms, depending on software type. The detailed description is presented in the
appendix.
General operator activities:
- entering numeric or text data with the module keys (in case of connecting scanner and
module keyboard the scanner is activated), e.g. product code,
- confirming of entered data upon the basis of information from computer database, e.g.
displayed product name, which code was entered earlier,
Do not drop weighed objects on the platform.

- searching of computer database resources, e.g. orders for realization are displayed
successively,
- entering parameters of balance indications, e.g. unitary weight during pieces number
measurement or tare,
- finishing transaction by sending measurement result to the computer, transaction
confirming or deleting,
- slip or self-adhesive label printing, which documents the measurement (transaction).
10. Special functions
Besides the basic metrological functions, weighing and tare setting, balances may have
special functions: automatic sending of measurement result, pieces counting, automatic
zeroing, comparing with threshold values. Special functions are available for user on
demand.
The available functions may be viewed after pressing the functional key “F”. The
functions are displayed with the successive numbers: F1-LIC, F2-AUt, etc.. During the
special functions switching the display shows the MODE indicator.
10.1. Function of automatic measurement result sending (F..-ATO)
This function allows for sending measurements results without using PRINT key.
Operations sequence:
1. Press key MENU of balance.
2. During displaying F...-ATO press ENTER.
3. To activate automatic mode, during displaying F..-1 press ENTER (F..-0 deactivates
automatic mode).
10.2. Function of setting threshold value for automatic balance operation
mode (F..-LO)
This function is connected with above function of balance automatic operation. It allows
for entering the threshold value, below each the balance indication must be to allow for
next measurement in automatic mode. By default value 0.5*MIN is used, and using LO
function is not required..
Operations sequence:
1. Press key MENU of balance.
2. During displaying F..-1 press ENTER.
3. Enter threshold value and press ENTER.

TECH ICAL A D MOTIO DOCUME TATIO
___________________________________________________________________________________________________

10.3. Function of comparing with threshold values (F..-tHr)
This function allows to compare the weighing result with two, previously programmed
values: upper and lower threshold. The comparison result is signalled on the display and
by acoustic signal, as well as with use of control outputs.
If the weighing result is:
- lower than the lower threshold (but higher than balance minimum) – balance does not
signal and activates output threshold I (option)
- between thresholds – the balance signals OK and activates output threshold II (option),
- higher than the upper threshold – the balance signals MAX and activates output zero
(option).
If the option of weighing with threshold signalling is selected, no activities connected
with the balance are required for this function to work. If the option is not selected,
balance operator may activate the function.
Operations sequence during function activation by the operator:
1. Press key MENU.
2. After displaying F..-tHr press ENTER.
3. The display shows in sequence:
F..-0 – function deactivation,
F..-1 – function activation,
F..-2 – checking of previously entered thresholds values.
4. After displaying F..-1 press ENTER.
5. The following options are displayed:
SEt-0 – weighing with signalling of thresholds exceeding,
SEt-1 - entering of lower threshold value (not used, when weighing with thresholds
signalling is selected in the computer),
SEt-2 - entering of higher threshold value (as above),
SEt-3 – zero signalization threshold setting.
6. Using ENTER key select option SEt-1.
7. Set the lower threshold value on the display, using the numeric keys and pressing
ENTER in the end.
8. Using ENTER key select option SEt-2 and enter the upper threshold value (as above).
9. Using ENTER key select option SEt-0. It activates balance operation with
simultaneous signalling of thresholds exceeding.
10. To finish the function operation press F key, then select F..-tHr and F..-0.
Checking of entered threshold values:
1. Press key MENU.
2. After displaying F..-tHr press ENTER.
The display shows in sequence: F..-0, F..-1 and F..-2.

3. After displaying F..-2 press ENTER. The display shows value of the lower threshold,
and after pressing PRINT key – upper threshold. If the printer is connected, threshold
values are printed.
4. Press PRINT key to switch to weighing.
Caution:
After the balance turning on both thresholds are set to maximum values. During upper
threshold setting pay attention, so its value is not lo er than the lo er threshold.
After the balance turning off and on this function remains unchanged.
10.4. Automatic zeroing function (AUt)
The function activation will cause automatic maintaining of zero indications, when the
pan is not loaded, or when zero reading has been achieved by pressing "T/
ON
" key.
Operations sequence:
1. Press key MENU.
2. When the display shows F..-AUT press ENTER.
3. The display will show F..-0 and F..-1.
4. Press ENTER when the display shows F..-1. On the left side "AUT" message will be
displayed.
5. To deactivate automatic tare setting function, perform section 1-3, selecting F..-0.
10.5. Pieces counting function (F..-LIC)
That function allows for counting the identical details, e.g. screws or transistors,
contained in the weighed batch, and may be used as auxiliary function, operating outside
of computer system.
The measurement takes place in two phases:
- first phase – calculation of single detail weight upon the basis of sample of specified
number of pieces
- second phase – counting the details in the weighed batch.
It is recommended, that the single detail weight is higher than the balance reading
graduation, and the weight of sample, used in the first phase is higher than 100 of
reading graduations.
Operations sequence:
1. Tare the balance pressing T.
2. Put the sample of 5, 10, 20, 50, 100, 200, or 500 pieces on the pan (pay attention so the
total load is not lower than 100 reading graduations).
3. Press MENU key to recall functions menu. During displaying F...-LIC press ENTER.
4. The display will show F..-0 and F..-1. Press ENTER when the display shows F..-1.
5. When next to F.. the number of pieces on the pan will be displayed (- -, 5, 10, 20, 50,
100, 200 or 500) press ENTER.

The balance displays number of pieces on the pan, which is indicated by pcs sign on the
display right side.
6. emove the sample, seta tare with ENTER key and put the portion of pieces on the pan.
Balance indication should be read as the pieces number.
7. To finish the function operation press MENU key, then, using ENTER key, select
F..-LIC and F..-0.
Notes:
The “Err-3” message means, that no sample is put on the pan. The same message is
displayed, hen the single detail eight is lo er than one reading graduation (user may
calculate the pieces, keeping in mind, that it increases the error).
Selecting “--“ in step 5 recalls previously entered value.
During pieces counting key T/
ON
performs its normal function.
After changing details type repeat the procedure from step 1.
11. Maintenance and small repairs
1. Keep the balance clean.
2. Take care, as during the operation some impurities may block the balance sensor and
bumpers. In case of contamination remove the impurities without disturbing sensor and
bumpers setting.
3. In case of improper operation due to short power failure, switch off the balance by
unplugging the power cable from the socket, and plug it again after a few seconds.
4. The message “Err-b”, displayed after switching on the unloaded balance, indicates the
balance sensor mechanical damage. In such case contact the nearest authorized service
point.
5. All repairs must be performed by the authorized personnel.
6. To perform the repair contact the nearest service point. List of authorized service point is
