PREPARING WORKING ENVIRONMENT

+18°C

+33°C

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

PREPARING THE BALANCE TO WORK

1. Take the balance, the feeder and
mechanical elements of the pan out.
It is recommended to keep the
original scale package in order to
transport the balance safely in
future.

2. Place the balance on a stable
ground not affected by mechanical
vibrations and airflows.

3. Level the balance with rotating
legs 6 so that the air bubble in water
level 7 at the back of the balance is
in the middle.

4. (For RV-300 and RV-500) Gently
insert the mandrel of pan support 2
into balance mechanism socket
through the pan ring 3 and the pan 1
on.

5. (For RV-3000 and RV-4000)
Place nuts 2 on mandrels that are
visible in balance cover holes, put
the pan 1 on nuts.

If the balance was taken from a lower temperature surrounding to a room

with higher temperature, e.g. in winter, moisture can liquefy on the balance

casing. Do not connect power supply to the balance, because this can cause

damage or improper work of the balance. In this case leave the balance for

at least 4 hours unplugged for acclimatization.

GENERAL OPERATION PRINCIPLES

1. Weighed sample should be placed in the centre of the pan

2. The balance allows taring in the whole measuring range. To tare the balance press

®T¬

key (on the left or on the right). 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 pan load easier and to avoid crossing measurement range, the
balance has a load indicator calibrated 0÷100% Max.

3. Weighing result should be read when the indicator " " lights, which signalises
stabilisation of a result.

4. When the balance is not used but should be ready to work immediately, it can be

switched off by pressing I/ key. The backlight of balance reading system is then
switched off and the balance enters into "standby" mode, in which the balance
maintains internal temperature and ability to start working with maximum accuracy.
Standby mode is signalled by the OFF indicator. To switch the balance on press I/

key.

5. In direct sale use (d=e), make sure that ®0¬ zero indicator is displayed before

sample is placed on the pan. If not, press ®0¬ key and wait until the balance is
zeroed and zero indicator appears. In other balances the key does not operate.

6. Balance mechanism is a precise device sensitive to mechanical shocks and
strokes.

7. After every change of balance position, level the balance and perform internal

calibration using key.

8. The balance cannot be used to weigh ferromagnetic materials due to decrease of
weighing accuracy.

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 balance. Autotests and internal calibration will
be performed.

Do not overload the balance more than 20% of maximum capacity.

Do not press the pan with a hand.

For transportation take off the pan (move it gently and lift it up) and pan

support (lift it up) and protect from any damages.

Steps after start-up of the balance:

Tests of electronic components.

Test of internal calibration motor test
(engine heard).

Displaying balance program version.

Starting internal calibration.

Zeroing the balance.

Loading internal weight.

Zeroing the balance

Balance is ready to work.

INTERNAL CALIBRATION

The balance is equipped with internal calibration system, which general task is to
maintain required measurement accuracy on the balance.
Internal calibration is the process of putting internal weight on automatically by balance
mechanism and correcting accuracy in balance firmware. The correction is necessary
because of differences between values of gravitational acceleration in the place where
the balance was manufactured and in the place where it is operated, as well as due to
changes of balance level and temperature.
Internal calibration is performed in the following situations:

AC-...

LO A D C

C

-CAL-

- When key is pressed,

- After defined time interval (for legally verified balances - 2 hours),

- After temperature change (for legally verified balances – more than 2oC).

In legally verified balances time interval is set to 2 hours and defined temperature
change is 2oC. In not legally verified balances those values can be set as calibration
options. Starting internal calibration process is signalled with - CAL - message.

In order to perform internal calibration, proceed with the following:

1. Empty the pan.

2. Press key (to leave internal calibration, press second time when “------“ is

displayed).

During calibration internal weight is put three times on and obtained results are
compared.
Discrepancy of results is signalled with a message and causes the balance being
blocked.
Until calibration process is finished do not perform any operation on the balance. Any
vibrations and shocks interfere calibration process and may delay it or deteriorate
accuracy of its result.
When internal calibration is performed successfully the balance indicates zero on the
display at empty pan.

BALANCE CHECKING

As weight indication depends on gravitational acceleration, it is advised to check
balance indication accuracy before and after series of measurement using any load
with known weight.
To check a balance with legal verification use calibration weight as stated in Technical
Data table with valid calibration certificate. In case permissible error is exceeded it is
advised to contact the nearest service to calibrate a balance.

CONNECTING THE BALANCE TO A COMPUTER OR PRINTER

The balance may send data to a computer or a printer via RS232C interface.

When cooperating with a computer, the
balance sends weighing result after
initialising signal from a computer or after
pressing key.

When cooperating with the balance, a
computer should be equipped with a
program that enables receiving and
processing data from the balance.

GRAM PRECISION offers computer programs to cooperate with balances. Demo
versions and program descriptions are available on the website: www.gram.es:

- Komunikacja – free serial port testing program,

- ProCell – residual program for cooperation with Microsoft EXCEL and other

Microsoft Windows applications (demo version).

Detailed information for programmers:

The balance sends data with a following method:

AVERAGE CALCULATION FUNCTION (AVErAGE)

The function allows for calculating average value of performed measurement series.
During series of measurements successive results are registered automatically when
scale indication is stabilised.

Press MENU key and select AUErAG
pressing ®T¬ key.
The following will be shown successively
on display:

- AUE oFF – leaving function,

- AUE on – measurement with average
calculation.

- out

Select AUE on using®T¬ key. It will
allow weighing with simultaneous storing
results into summing register for average
calculation
Measurement registration is performed
automatically in the moment when scale
indication becomes stable. Short time
displaying of „ - - ” denotes that load can
be taken off and new one can be put on.
Results above scale Min are registered
only. Number of measurements is limited
to 9999.

In order to read average value key
should be used.

- first pressing causes displaying number

of measurements (n).

- second displaying causes displaying

average value (=).

- third pressing allows continuing

average calculation.
If a printer is connected to scale the
following report will be printed :

In order to finish calculation press MENU key and then select AUEr i AUE OFF.

TRESHOLD COMPARING FUNCTION (thr)

This function allows comparing weighing result with two programmed reference values:
lower and upper threshold. Comparison result is signalled with indicators (MIN, OK,
MAX) and sound signal generated when threshold values are exceeded.

Operation sequence:

Press MENU key and choose thr
pressing ®T¬ key.
The following options are displayed
successively:

- trESh oFF – deactivate the function,

- trESh on – activate the function,

- trESh Prn – check last threshold values

(press key several times),

- thr CFG – function configuration

(working mode, buzzer, flashing setting).
Choose thr on option using ®T¬ key.

The following options for entering
thresholds are displayed:

- SEt-0 - go to weighing with signalling
threshold excess,

- SEt-1 - set lower threshold value,

- SEt-2 - set upper threshold value,

- SEt-3 - set zero signalisation threshold.

Using ®T¬ key select SEt-1 option.
Set lower threshold value using the
following keys:

- digit increase,

- decimal point,

®T¬ - move to next digit,
MENU - finish.
Then select SEt-2 option and enter upper
threshold value.

Choosing Set-3 option will cause starting
work with signalisation of exceeding
thresholds and zero.
To leave the function, press MENU key
and then choose thr and thr-0 options.

If the comparison result is :

- smaller than lower threshold – the scale signals MIN (yellow colour),

- between threshold values - the scale signals OK (green colour, with the short sound
signal),

- greater than upper threshold - the scale signals MAX (red colour, long sound signal).

The checkweighing results can be use to control:

- optical indicator (Indication mode),

- batching devices (Batching mode).

If we choose thr CFG option following options will appear:

- thr Out (working mode setting),

- thr buZ (buzzer work settings: EHC – buzzer turns on after exceeding threshold; STB

– signal on after result stabilization in OK section),

- thr FLA (flashing on when lower or upper threshold is exceeded)

- out

User can choose from 3 working modes for thr out.
After choosing thr Out option following options display:

- Out off,

- Out IPL (batching mode),

- Out bSt ( level mode),

- Out SGn (indication mode).

Standard scale is set for cooperation with optical indicator.

On the chart below output states are shown during increasing load on the scale for both
working modes:

It is advised to use MS3K/P electronic board (sold separately), consisting of RM96P
transmitters, with DC24V input voltage and AC250V, 3A output.

Important notes:

1. After switching the scale on, both thresholds are set to maximum values.

2. When setting upper threshold value, pay attention that its value is not below lower

threshold value.

3. Setting lower and upper threshold value is possible after sending appropriate orders

from computer, what is described in scale user manual

.
