5. WEIGHING
Put load on the scale. Time of stabilization is about 3s.
5.1. MULTI-RANGE BALANCE For the balances made as dual range version all functions and possibilities of setting are accessible the same as for one range balances. Switching between ranges is done automatically without operator’s interference. Marking for weighing in the II measuring range is in the upper part of the display.
Procedure of the multi-range balance If the load is increased on the pan the load is weighed with accuracy for I sub range. If the limit is exceeded switching between accuracies is done automatically – the load is weighed with II sub range accuracy. Return to weighing in I sub range accuracy is possible if there is no load on the pan and the balance show precise zero.

6. TARE AND SETTING TO ZERO
To define net mass put container on scale and after stabilization - press TARE (mass indication returns to zero, sing appears on display). Net mass appears on display after putting load on scale.
Tara can be done many times in all measure range of scale. It’s not allowed to exceed max measure range. After taking load and container off summary of tared mass with minus sign appears on display.
Setting to zero Setting stage of display to zero is possible only in range to ± 2% of max capacity of balance. If this value is higher than ±2% of max capacity display shows order <UAL 4>. Setting to zero is possible only with stable stages on display. Setting to zero is the same as defining new zero point which is precise zero for scale.

8. WEIGHING WITH AVERAGE RESULT <AUE>
Result of weighing from few measurements is presented as average. It’s help full when conditions of work are not stable (vibrations, waves). To get result of measurement with assumed precision it’s necessary to use digital filter with higher stage.
Procedure: • press F key repeatedly, till AUE appears on display • press PRINT key or one of following number which is equivalent
chosen amount of average 1 - average I result of digital filter stage 2 - average II result of digital filter stage 3 - average III result of digital filter stage 4 - average IV result of digital filter stage 5 - average V result
• press F key to confirm choice. Balance return to weighing. Notice: Increase stage of average makes times of weighing longer.
9. DEGREE OF FILTER <FIL>
In order to make operation of balance comfortable parameter of setting size of filter is introduced in additionally. This parameter has influence on stability of result depending on conditions in place of usage. Procedure:
• Press F key many times until order FIL appears on display: • By pressing PRINT key choose one of following numbers that refers
to chosen step of average:
1 – I step of filter 2 – II step of filter 3 – III step of filter 4 – IV step of filter
• Press F key to confirm the choice. Balance return to weighing.
Notice: Increase of step of filter causes extension of time

10. SETT-UP SPEED OF TRANSMISSION <bod>
External mechanism connected to socket RS 232 has to be supplied from common net f.eg. with common protection against shock (lack of difference of electric potencial on conductors of balance and attached mechanism).
Parameters of transmission recorded in balance • Speed of transmission - 4800 bit / s • Data bits - 8 • Stop bit - 1 • Control of parity - lack.
Value shown on balance display can be sent to external mechanism by connection in one of three ways:
• Manually – after press PRINT key • Automatically – after stabilization enunciators • For request of external mechanism – see additional functions „List
of orders balance - computer”. Value on display can be sent by connection as: − stable – start sending information after stabilization result of
weighing
− not stable
Way of setting speed of transmission:
− Press F key repeatedly until order bod appears on display − Press PRINT key repeatedly until number of chosen speed of
transmission appears on display
bod 1 - 300 bit / s, bod 2 - 600 bit / s, bod 3 - 1200 bit / s, bod 4 - 2400 bit / s, bod 5 - 4800 bit / s, bod 6 - 9600 bit / s,
− Confirm by pressing F key.
11. COUNTING PIECES WITH THE SAME MASS
Scale in standard made is provided with option of counting small pieces with the same mass. Function of counting pieces doesn’t work with other functions of scale.
To use this function:
• Put package on scale and tare its mass to balance memory - TARE, appears sing NET on display, near description Net. There will be small elements put into the box.
• Put as many elements to scale as many we declare as batch quanta in package
• Press F key until order PIECE appears on display • Press key PRINT to start set up batch quantity
• Press F key - choose value (you can select from 10, 20, 50pcs or free definable)
• If you want to start the counting pieces function, please choose one of the values, eg. 20 pcs and press PRINT key
- 13 -
• After displaying of LoAd information, please put on the pan of the balance as many pieces as have been chosen (20pcs).
• If option Free was chosen, the display will show the number of pieces with flashing of the first digit – you should inscribe as many pieces are in the mass pattern
• set up batch quantity by means of keys TARE – choose digit
PRINT – choose value
- 14 -
• confirm by pressing key F - LOAD appears on display
• after making sure that batch with declared quantity is put on scale confirm by key PRINT once again - balance displays Process, and then amount of elements and PCS.
• after adding or take counted elements off scale their amount appear on display
Return to weighing mode
• press key F many times until - PIECES appears on display
• press TARE key
Balance return to weighing mode and diode with kg or lb mark starts flashing
Attention: 1. If you choose batch quantity remember that precision of counting depends on
metrological parameters of balance and on repeatability of mass singular counted elements.
2. Result of measurement is more precise if batch quantity is bigger 3. If summary mass of batch quantity is less than 5 reading divisions (5d) – balance
shows order about error -LO- and return to weighing automatically.
- 15 -
12. CONTROL +/- ACCORDING TO MASS OF MEASUREMENT STANDARD <StEPS>
Software of the balance enables to check mass of weighed load in reference to defined range of tolerance. Control +/- doens’t cooperate with other functions of balance.
Procedure: • press F key repeatedly , till StEPS appears on display • press PRINT key to start programming value of threshold
TARE – choose digital PRINT - choose value of digital F – confirm settled value
TARE - choose digital PRINT - choose value of digital F - confirm settled value
From now additional annunciators appear on display:
When mass of load on scale is lower than down limit of settled range
If mass of load on scale is between programmed values of range
- 16 -
When mass of load on scale is bigger than upper limit of defined range ATTENTION:
If the limits of range are sett-up in wrong way (value of down limit is bigger than value of upper limit of range) balance shows order about error -LH- and returns to weighing mode.
Return to weighing mode: • press F key repeatedly till order StEPS appears on display • press TARE key
13. CALIBRATION (option) To assure very precise weighing introduce correction factor to balance memory – it’s calibration. Scales have system of external calibration. Procedure

18. AUTOZERO FUNCTION
(Option for not verified scales) To have precise readouts from balance we have function AUTOZERO. This function is to control and correct zero of balance showings – thanks to this measuring always begins from exact zero. There are special cases when this function disturb when measuring. For example when putting very slowly loading on the pan. Correction set of showing zero, can correct also readouts of real mass of loading. In this case there is possibility to block this function. Procedure: − many times press F, on a display you will see:
AUTO − with key PRINT chose one of two possibilities:
AUTO 0 (function AUTOZERO ON) AUTO 1 (function AUTOZERO OFF)
− approve with F.
19. AUTOMATIC TURN BALANCE OFF
This function is necessary to save-up the battery. The scale switches off if no weighing is done during last 5 minutes (function t1 = 0). This function can be switched off if it disturbs in work or if the supply is before.
Procedure:
- press the F button until command t1 appears on the display
- 22 -
- press the PRINT button to select one of two values:
t1 0 - function „Automatic turn off” is active (for battery and accumulator work)
