3. Safety rules
It is necessary to follow safety rules of work with the
scale shown below. Obeying those rules is the
condition to avoid electrical shock or damage of the
scale or connected peripheral devices.
• All repairs and necessary regulations can be made by authorised
personnel only.
• To avoid fire risk use a feeder of an appropriate type (if feeder is
supplied with the scale) and supply voltage has to be compatible with
specified technical data.
• Do not use the scale when its cover is opened.
• Do not use the scale in explosive conditions.
• Do not use the scale in high humidity environment.
• If the scale seems not to operate properly, switch it off and do not use
until checked by authorised service.
According to current acts of low about protection of
natural environment, wasted scales should not be put
into waste containers together with ordinary waste.
• Wasted scale after operation period can be delivered to units authorized
for gathering wasted electronic devices or to the place where it was
bought.

7. Preparing working environment
+18°C
+33°C
Location for the scale should be chosen with care in order to limit influence of
the factors that can interrupt working scale. This location has to maintain proper
temperature for working scale and necessary space for its operating. The scale
should stay on stable table made of material that does not influence magnetically
on the scale.
Rapid air blows, vibrations, dust, rapid temperature changes or air humidity over
90% are not allowed in scale surrounding. The scale should be far from heat
sources and devices emitting strong electromagnetic or magnetic fields.

10 USER MANUAL
__________________________________________________________________________________________________________________
8. Preparing scale to work
1. Take the scale and feeder out of
the package.
2. Place the scale on a stable
ground not affected by mechanical
vibrations and airflows.
3. Level the scale using rotating
legs 6 so that the air bubble in
water level 7 at the back of the
scale is in the middle.
4. Put draft shield 8 on the scale
and cover 9 on it.
Scale should be transported in the way, that there is no risk of
accidental pressing or overweighing a pan.
If the scale was taken from a lower temperature surrounding to a room
with higher temperature, e.g. in winter, moisture can liquefy on the
scale casing. Do not connect power supply to the scale, because this
can cause damage or improper work of the scale. In this case leave the
scale for at least 4 hours unplugged for acclimatization.

USER MANUAL 11

9. General operation principles
1. In order to confirm correctness of the scale during its operation, before
starting and after finishing every valid measurement series it is recommended
to check weighing accuracy putting calibration weight or other object of
exactly known mass on the scale. In the case when allowable measurement
error of the scale is exceeded, it is recommended to perform calibration with
external weight or contact authorised service centre.
2. Weighed mass should be placed in the middle of the pan.
3. The scale allows taring in the whole measuring range. To tare the scale press
→ T ← key. Taring does not extend measuring range, but only subtracts tare
value from mass value of a sample placed on the pan. To make the control of a
load on the pan easier and to avoid exceeding measurement range, the scales
have load indicator calibrated 0÷100%.
4. Weighing result should be read when the indicator lights, which signalises
result stabilisation.
5. When the scale is not used but it is necessary for it to be ready to work, it can
be switched off by pressing I/ key. The scale reading system is then switched
off and scale goes to standby mode signalled with OFF indicator. Switching
the scale on is preformed by pressing I/ key.
6. In sales having
→ 0 ← key (zeroing) active it should be checked if zero
indicator
→ 0 ← is displayed before sample is placed on the pan. If not, press
→ 0 ← key and wait until the scale is zeroed and zero indicator appears. After
that load can be placed on scale pan.
7. Scale mechanism is a precise device sensitive to overweight, mechanical
shocks and strokes.
Do not overload the scale more than 20% of maximum capacity.
Do not press the pan with a hand.
For transportation pan, pan support and pan ring should be packed
separately.

10. Operation rules during work with accumulators (batteries)
1. Scale can be powered from ~230V supply through feeder attached with scale.
Moreover accumulators, which are placed in container inside the scale, can be
used for powering. Ordinary batteries can be used as well.
2. In order to make accumulators (batteries) discharging time longer, automatic
switching off display backlight and next the whole scale is possible during
breaks in weighing. onfiguration of these mechanisms is done using
b_LIGHT and Auto OFF functions.
3. harging accumulators is performed automatically after connecting feeder to
the scale, also during weighing. Accumulator power level can be read using
bAttErY function (bat VoL option).
When using batteries in place of accumulators, charging during
work with feeder have to be switched off. bAttErY function is used
for this purpose (bAt OFF option), which is described in further
part of manual. harging batteries can cause their breaking and
serious damage of the scale.

USER MANUAL 13
__________________________________________________________________________________________________________________
11. Accumulators (batteries) replace
1. Take pan, pan support and pan ring carefully.
2. Turn the scale upside down.
3. Unscrew screws 11 holding cover 12, take cover off.
4. Take accumulator container 1 off and put 4 AA format accumulators in it. The
way of placing accumulators into the container is shown on the picture above and
draft in the container:
Not controlled press on the pan can cause mechanical damage of
the scale.

12. Start-up
Plug feeder into ~230V power supply socket. When the pan is empty plug feeder
output connector into 12V socket at back of the scale. Autotests and internal
calibration will be performed.
Steps after start-up of the scale:
Tests of electronic scale components.
Showing scale program version.
Zeroing the scale.
Ready to work.

USER MANUAL 15

13. Connection with computer or a printer
The scale may send data to a computer or a printer via RS232 interface.
When cooperating with a computer, the
scale sends weighing result after
initialising signal from a computer or after
pressing key on the scale.
For cooperation with the scale a computer
should be equipped with software
allowing receiving data from the scale
and using it further.
AXIS offers computer programs to cooperate with scales, available on
www.axis.pl website:
- ommunication – free program for sending simple commands to the scale and
receiving weighing results,
- Pro ell – program for cooperation with Microsoft EX EL and other
Microsoft Windows applications (demo version).
Detailed information for programmers (LONG protocol):
When cooperating with a computer, the scale sends data as follows:
omputer → Scale: S I R LF (53h 49h 0Dh 0Ah) - initiating signal,
Scale → omputer: scale sends 16 data according to the following format:
(16 Bytes, transmission parameters: 8 bits, 1 stop, no parity, 4800 bps),
Description of particular bytes:
Byte 1 - „-“ sign or space
Byte 2 - space
Byte 3÷4 - digit or space
Byte 5÷9 - digit, decimal point or
space
Byte 10 - digit
Byte 11 - space
Byte 12 - k, l, c, p or space
Byte 13 - g, b, t, c or %

15.1. Customization of special functions menu (ACtIV and dEFAULt)
The function allows choosing among
available special functions these,
which will be displayed after pressing
MENU key. It helps to avoid
displaying all available functions,
what can make operation time longer.
To distinguish ACtIV function from
function menu list, indicator is
displayed on the left side.
In every moment it is possible to
restore primary (manufacture) settings
choosing dEFAULt special function.
The example on the left shows the
operations of adding function for
setting parameters of serial interface to
function menu.
In order to remove a function from
menu, choose Prt oFF in place of
Prt on in the last step of the example.
