Load a weighed object on balance’s weighing pan. On stabilization of weighing
result, indicated by stability marker visible on the side of balance’s display,
read the measurement result.
Saving / printout of the measurement result is available on pressing <PRINT>
key:
• In case of verified balances – only stable measurement result can be
saved or printed (stability marker visible on balance’s display)
• In case of non-verified balances – stable or unstable measurement
result can be saved or printed (regardless of stability marker
presence). If unstable measurement result is printed then it is
accompanied by question mark <?> in front of printed mass value.
10.1. Selection of measuring unit
Change of measuring unit is carried out by pressing the measuring unit icon
visible next to the value of measurement result on balance’s display. Pressing
the measuring unit icon opens a list with available units. On selecting one of
them, the software automatically calculates the indicated mass value to the
active measuring unit.
Available measuring units:

* - Accessibility of measuring units is conditioned by type of balance and its
verification status.
In non-verified balances all measuring units including those outside the
International System of Units are available.
10.2. Means of correct weighing procedure
In order to ensure long lasting use of a balance, correct and reliable
measurement of weighed loads, follow below procedures:
Start the balance with no load on the weighing pan
(permissible value of load on the weighing pan on balance start is
±10% of its maximal capacity).
Load balance’s weighing pan steadily with no shocks:
YES
NO
Place weighed loads centrally on the weighing pan:
YES
NO
Avoid side loading, in particular side shocks:
NO
NO

10.3. Balance leveling
Balance Y2 series features AutoLEVEL System, which continuously monitors balance’s level
status during its operation. The level status is signaled in the upper right corner of balance’s
display. The system continuously controls level, and on detecting level change it indicates
appropriate information on the display and/or signals an alarm. Then the software opens a
window for adjusting the level.
Balance leveling procedure
• Press level status pictogram < > located in the upper right corner of the
display.
• The display indicates a control panel of leveling function. Balance operator
previews level status, and balance’s top elevation.
• Level the balance by turning the adjustable feet in a way indicated by
blinking pictograms on the display < > – the level point should move
towards the center of the level circle.
• As the level point is in the center point, its colour changes from red to
green – which is a confirmation for correct level status.
10.4. Zeroing
In order to zero mass indication press key.
The mass indication on the display should equal zero, and precise zero and
stability markers should appear.
Zeroing process is tantamount to determining new zero point recognized by
the balance as precise zero. Zeroing is possible only in stable status of display
indication.
Caution:
Zeroing the display indication is possible only within the ±2% range of
instrument’s maximal capacity. If zeroed value is above the ±2% of the
maximal capacity, then the software indicates an error message Err2.

10.5. Tarring
In order to determine net weight of a weighed object, place object’s container
(packaging) on balance’s weighing pan, and on stabilization of measurement
result press key. The display should indicate mass equal to zero and
symbols: Net and . On taking off the weighed load and its packaging from
instrument’s weighing pan, the display indicates sum of total tarred mass with
minus sign.
The software also enables assigning tare value to a product from a database.
Then, on product selection from a database, the software automatically
uploads data on tare value for the specific product.
Caution:
Tarring negative values is impossible. On tarring negative values the balance
responds with an error message. In such case zero balance’s indication and repeat
tarring procedure.
Manual tare determination
Procedure:
• While in optional mode press quick access key ,
• Which opens numeric keyboard on balance’s display,
• Using numeric keys insert desired tare mass and press key,
• The balance returns to weighing mode, and the display indicates inserted
tare value with minus “–“ sign.
Deleting tare
The tare value indicated on balance’s display can be deleted by pressing ZERO
key on balance’s front panel, or using programmable function key <Deactivate
tare>
PROCEDURE 1 – on taking the tarred load off balance's weighing pan
• Press ZERO key
• The NET marker is deleted, and new zero point of the balance is determined
PROCEDURE 2 – when the tarred load in on balance’s weighing pan
• Press ZERO key
• The NET marker is deleted, and new zero point of the balance is determined
• If tare value exceeds 2% of balance’s maximal capacity, the display
indicates error message –Err- (forbidden operation)
PROCEDURE 3 - when the tarred load in on balance’s weighing pan or on
taking the tarred load off balance's weighing pan
• Press programmable key <Deactivate tare>
• The NET marker is deleted,
• The display indicates tare value
• Press <Restore tare> key to restore the last tare value
