POWER SUPPLY AND BATTERIES REPLACEMENT
The Load Cell Tester is powered by “AA” size batteries :
Use four x 1.5 V Alkaline Disposable Batteries or 1.2 V Ni-MH Rechargeable Batteries
The battery life depends on the number of load cells being powered and the intensity level of the LCD display.
Min. consumption is about 125 mA (single 350 Ω load cell with display intensity at intermediate level).
Max. consumption is about 190 mA (four 350 Ω load cells with display intensity at maximum level).
The life of alkaline disposable batteries is about 4 hours in continuous operating mode*, at the max.
consumption.
The life of the Ni-MH rechargeable batteries depends on their capacity (expressed in mA per hour).
For example, with 4 x 2000 mAh batteries, the battery life is over 8 hours in continuous operating mode*, at
the max. consumption (2000 mAh/190 mA = 10,5 h).
Even though the theoretical limit exceeds 10 hours, the auto shut-off takes place sooner in order to assure
the full functionality of the Load Cell Tester and to avoid completely discharging the batteries.
* By “continuous operating mode” we mean that the Load Cell Tester switched-on continuously.
Setting the “auto shut-off” parameter will extend the battery life (see page 16 for additional information).

MAIN PERFORMANCES
Even if the 2 main functions performed by the Load Cell Tester are independent, they
allow to carry out the complete analysis of any weighing system composed by load cells (up
to 4) and weight indicator.
This mode is used to diagnosis the load cells.
The display shows the following group of parameters:
1. The signals coming from the load cells (mV/V values)
2. The distribution of the weight on the load cells (% values)
3. Load on each load cell compared with its nominal capacity (% values)
4. Weight value on each load cell (expressed in the selected measurement unit: g, kg,
Ton, lb, N, kN)
Values 3 and 4 are only displayed if the parameters described on pages 15 to 17 have been
programmed.
Faulty load cells or bad connections*, zero offset drifts or unstable signals can be easily
detected.
* These messages appear on the display in the following conditions:
1. “EXC +” indicates a problem with the + Excitation lead
2. “EXC -” indicates a problem with the - Excitation lead
3. “SIGNAL” indicates a problem with one of the Signal leads
The 1006 Tester in this operating mode allows to view the peak values of each load cell.
The peak value cab be enabled or disabled, for all the 4 groups of parameters above
described by pressing long the key 5. To erase peak values detected, press key C.
In this mode the load cell tester is used to calibrate or check out the weight indicator.
A signal of up to 20 mV can be generated and used to check the linearity and to check or
calibrate the Zero and Span of any weighing instrument.

Display Division Value
The Display division value can be selected from a list (0.001 to
100, expressed in the measurement unit previously enabled).
The LC Tester automatically offers a value optimised to 10000
counts, based on the nominal capacity of the load cells (sum
of the load cell’s single capacities).
Example: Single LC capacity = 250
Number of load cells = 4
LC’s Total capacity (250 x 4) = 1000
The Display division value automatically offered by the LC
Tester will be: 0.1 given by the ratio:
LC’s Total capacity _1000_
10000 10000
However the User has the chance to modify this value (+ or -),
bearing in mind that the maximum number of counts can
be 50000.
Considering the example given here above, the ratio:
LC’s Total capacity
50000
equals 0.02.
This will be the minimum usable Display division value.

Through this function the LC Tester acts as a mV generator, therefore it can be used as a load cell simulator
and/or calibrator for electronic weighing instruments, to check linearity, to check 0 and FS, to perform 0 and FS
calibration.
Refer to page 9 for wiring.

In order for the “CALIBRATOR” function to work correctly, the following parameters
“Number of LC’s”, “LC’s sensitivity” and “Single LC capacity” programmed in the LC Tester
must be the same as those programmed in the instrument to be controlled.
Example:
If the instrument to be controlled is normally connected to 4 load cells 250 kg each, 2 mV/V,
the LC Tester must have been programmed with the same data (see pages 15-17):
Number of LC’s = 4 - LC’s sensitivity = 2.0000 - Single LC capacity = 250.
Load cells excitation voltage coming from the instrumentation.
mV signal generated by the LC Tester and sent to the instrument.
This value is the product of “mV/V” multiplied by “Vin”.
Weight value corresponding to the mV/V signal generated by the LC Tester.
The weight value is expressed in the preselected measurement unit and its Full Scale is
the product of “Single LC capacity” multiplied by “Number of LC’s”, programmed in the
“WEIGHING PARAMETERS” menu.

Zeroing the weight value shown on the LC Tester
This function helps the User during the zero and full scale calibration of the weighing instrumentation.
After having performed the zero calibration on the instrument, the user can set to zero the weight value
displayed by the LC Tester also, so that the weight values displayed by the two devices can match.
Example: weighing system comprised of an instrument connected to 4 load cells 250 kg each - 2 mV/V (total
1000 kg), dead load = 200 kg, live weight = 600 kg.
The 0 calibration must be performed with a signal of 0,4 mV/V (equivalent to 200 kg), while the F.S. calibration
must be performed with a signal of 1.6 mV/V (equivalent to a signal increment of 1.2 mV/V = 600 kg)

Software program for saving the Configuration Files
It is also possible to save the all weighing parameters for up to 10 different systems.
This file configuration can be strored directly inside on the LC tester and than transferred to the PC via the
RS-232 serial port.
All of the data (number of load cells, capacity, sensitivity, unit of measurement, division value) can be stored
in up to 100 different files which can be recalled when needed. This feature expedites load cell tester set-up
time by eliminating the need of having to re-enter all of the parameters.
It is also possible to save the zero and f/s mV/V values for each system for ease of any periodical checking.
The configuration files can be set and stored directly from the instrument’s keyboard, or with an Excel chart
which can be created on a PC and then transferred to the LC Tester via the RS-232 serial port.
The bi-directional communication feature allows transferring the files from the load cell tester to a computer.

The LC Tester 1006 guarantees the download of the complete configuration of the indicator and can send it to
a PC for storage.
By the bidirectional RS232 communication the same files can be transferred from PC to Tester 1006 and then
to the indicator.
The LC Tester 1006 can immediately send the complete configuration to a new instrument.
The instrument, that received the configuration, is ready to be used on the plant.

CONFIGURATION FILE MANAGEMENT
This section of the manual covers an OPTIONAL function that can only be activated
by purchasing a PASSWORD.
Please contact the Manufacturers Sales Department for Terms and Conditions.
Please refer to page 25 for a general description of the Configuration File
Management option.

Page 29
The CONFIGURATION FILE MANAGEMENT
This function enables storage of up to 100 Configuration Files inside of the Load Cell Tester, each File
contains all the weighing parameters for up to 100 different systems.
The Configuration File management is performed using the Save, Open, Delete, Transfer File functions.
Each file is identified by a name consisting of 8 alphanumeric characters.
The Configuration File function expedites load cell tester set-up time by eliminating the need of having to
re-enter all of the parameters.
The following weighing parameters can be stored in each configuration file:
Number of load cells (see page 13)
Load cell nominal capacities (see page 15)
Unit of measurement for the weight values (see page 15)
Individual load cell sensitivities (see page 16)
Display division value (see page 17)
It is also possible to save the zero and f/s mV/V values for each system for ease of any periodic checking.
These stored mV/V values can be generated by the Load Cell Tester when being used as a “Calibrator”, in
order to calibrate the Zero and Full Scale of the instrumentation installed in the weighing system.
The configuration files can be set and stored directly from the instrument’s keyboard, or with an Excel chart
which can be created on a PC and then transferred to the LC Tester via the RS-232 serial port.
The bi-directional communication feature allows transferring the files from the load cell tester to a computer.

STORING THE mV/V LOAD CELL SIGNALS
This function is used to save the individual zero and span mV/V signals coming from the load cells into the
instruments memory.
Both the Zero and Span values can be saved (by “Zero” we mean the mV/V values coming from the
load cells when the weighing system is unloaded; by “Span” we mean the mV/V values corresponding
to a known weight applied on the weighing system).
The span value may not necessarily coincide with the weighing system’s full scale value.
The mV/V values can only be stored when the instrument is in “Load Cell Tester” mode, and the “mV/V
Input Signals” display view is selected (see Figure 1 on page 14).
The stored values are automatically associated to the Configuration File currently in use.
The stored mV/V values can be used as reference values for performing periodic checks on the load cells.
When operating the load cell tester in “Calibrator” mode, it can be used to generate a zero and span mV/V
output signal (based on the average of the individual signals) that were previously saved in memory.
These signals can be used to check or calibrate the Zero and Span of the weighing systems instrumentation.
The mV/V signals representing zero and span can only be saved into the load cell testers memory when:
The load cell tester is displaying the “mV/V Input Signals” (see Figure 1 on page 14).
One of the Configuration Files has been opened (see page 30)
Procedure:
Acquiring the Zero mV/V signals
Make sure that the weighing system is empty or unloaded prior to performing the following operation:
Press and hold the

key to save the zero mV/V signals
Once the Zero mV/V signals have been acquired, the following message appears momentarily on the display:
