6. Security rules
To avoid electrical shock, scale or other connected peripheral devices
damage, it is necessary to follow the security rules below.
To supply the scale use power outlet with protective contact (not for scales with external
feeder).
Repairs and essential scale regulations can be made only by authorized personnel.
To avoid fire risk use a feeder of an appropriate type (supplied with a scale). Pay attention
that supply voltage is compatible with specified technical data.
Do not use a scale when its cover is opened.
Do not use a scale in explosive conditions.
Do not use a scale in high humidity.
If a scale seems not to operate properly, plug it out of the mains and do not use it until
checked by authorized service.

9USER MANUAL ME-03
7. Rules proceeding with used up scales
According to obligatory rules concerning environment protection used
electronic devices should not be put in a container with normal waste.
•After exploitation used scale should be given to special units authorized to collect used
electronic equipment or to the place where the device was bought.

10 USER MANUAL
8. Assembly and connecting tensometric sensors
To build a scale basing on ME-03 indicator contact authorized manufacturer.
To comply CE marking requirements, for connecting the wires use filtering core 20mm.
The core should be placed within 30mm from the place of its connection.
Single strain gauge scheme inside ME-03:
When 6-wires connection of strain gauge transducers is used (REF+ and REF) jumpers shown on the picture
above should be soldered out from the main board (jumpres connect REF+ with EXC+ and REF- with EXC-
).
Before connecting sensors to the indicator unplug the device from the mains
to avoid damaging the indicator.

Caution:
The galvanic connection of sensors and adder housing is necessary.
In normal conditions grounding is made only by using W conductor.
In conditions of increased electrostatics grounding should be made with additional Z conductor (minimum
2,5 mm2).
Connect conductors from external devices to meter sockets, led out wires or to bar on supply board inside
the meter (option). During leading out wires from meter housing use hermetic culverts in housing.
All devices connected to the scale should be supplied from the same phase
230V.

9. Meter connections description
ME-03/N/GLCD:
9.1 Threshold interface
P1-P3 (THRESHOLDS) outputs are used to connect dosing or signalling (option) devices. There are opto-
isolators of an open collector type with 50mA / 24V maximum load. They can be connected directly to
transmitters inputs or to MS3K/P board offered by AXIS separately or in ST 3K/P control box (3 transmitters,
own power supply)..
Optional indicators outer wires have digital markers.

Direct connection of transmitter to THRESHOLD output diagram:
* in option without an interface –10 is in the place of 8
Outputs are adapted for direct connection RM96P transmitter of DC24V input voltage and AC250V 8A
output. Transmitter’s coil has to be secured with diode e.g. 1N4148.
It is recommended to use MS 3K/P electronic board (3 transmitters of RM96P type –max. load of 3A/250V)
or complete ST 3K/P control box (feeder, 3 transmitters like above).
9.2 External keys
The input of external keys allows to place (make double) selected scale keys into control box or operator’s
workstation. As a standard the input is taken out with a wire for direct connect to a control panel. ME-03
meters can be eqipped with external keys (option od demand).

External key connecting is shown below. It is crucial to use external supply (24V) in order to make current
flow through scale transoptor input. This way of connection provides galvanic separation of the scale from
automatics systems which increases resistance to external interference and increases reliability.

a computer is possible after logging the scale in with 02h scale number command. To log the scale out use
03h command.
For example: Using a program to test RS232 interface ( program is available in www.axis.pl / programy
komputerowe ) for scale number 1 please write: $0201 to log in, then SI, and write: $03 to close
communication.

Attention:
1. Except variable signs constant signs can also be inscribed e.g. factory name, product name and so on.
2. In standard only one label pattern is possible to printout (number 0001). Using bigger amount of
patterns (other label numbers) is possible thanks to LAbEL special function.
3. To achieve label printout, label printer must have inscribed label pattern (label pattern is created on
computer and using computer it is saved to label printer memory). Label pattern is designed by ZEBRA
DESIGNER program which is supplied together with label printer.
4. Scales parameters and transmission protocol must corespond to label printer type.
WE-05 connection cable (connects scale with ZT230 label printer –MM adapter also
required; can be also used to connect scale with computer)

18 USER MANUAL
10. Exploitation general rules
1. Before each measurement make sure that zero indicator is displayed. If zero indicator does not display
or “----“ communicate appears, press 0key and wait until zero indication and zero indicator appears.
2. The scale is equipped with a tare equal to its range. To tare the scale press Tkey (left or right).
Storing a tare value does not extend measuring range, but only subtracts it from a load placed on a pan.
To make weight control easier and to avoid range overdrawing, the scale (with LCD) is equipped with a
load indicator (graduated in percentages).
3. Weighing result should be read when the indicator " " lights, which signalises result stabilization.
4. When the scale is not used but it is necessary to be ready to work immediately, it can be switched off by
pressing I/ key. The scale reading system is then switched off to "standby" mode (signalled by the
indicator "OFF" in version with the LCD display). To switch the scale on press I/ key. The scale is
immediately ready to operate maximum accuracy (after self tests).
5. Weighed sample should be placed in the centre of the pan.
6. Protect the scale against dust, aggressive dusts and liquids. To clean the scale wash it with water with
soap and dry it afterwards.
7. A scale equipped with accumulators (option) automatically charges during normal work with feeder and
controls accumulator state. Charging control is executed by bAtterY special function. The function enables
to readout charging state and also to turn off charging in case of using normal batteries (instead of
accumulators). Meter signalizes an accumulators discharge on LCD display and after around 1h the scale
switches itself off to avoid discharging the accumulator below threshold voltage.
After discharge signalising appears an accumulator should be charged as quickly as possible by
connecting external feeder. Charging is more effective when scale is turned off with I/ key, then charging
time is about 10 hours..
Place the scale on a platform to avoid dropping weighed objects on
the pan.
Do not overload the scale more than 20% of maximum load (Max).
Do not allow to fully discharge the accumulator as this could
damage it!

19 USER MANUAL ME-03
11. Balance checking and adjustment
It is advised to check scale indication accuracy before and after series of measurement using any load with
known weight.
To check the scale with legal verification use a calibration weight with valid calibration certificate. In case
permissible error is exceeded it is advised to contact the nearest service to calibrate the scale.
Adjusting (calibration) scale should be made if the scale precision is not sufficient. A standard
of mass should be used with Max value taken from scale technical data table. In case of
legalized scales with inaccessible calibration (secure seal) contact with service is
recommended.

20 USER MANUAL
12. Start-up
In scales with direct supply when pan is unloaded put
the plug into socket.
In scales with external supplier connect the supplier
plug into meter and then (if scale is unloaded) plug it
to wall socket.
Scale turning on sequence:
Producer data.
Scale tare.
Zero indication means that the scale is ready to work.
Attention: UnLOAd communicate means that the
scale is loaded or transport secure elements located
under the scale’s platform were not taken out.
