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.
Function for testing the load cells
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
Load Cells Peak Function
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.
Transducer Simulator / Calibrator Mode
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.

CGS4/C and CEM4/C SUMMING JUNCTION BOXES
The CGS4/C and CEM4/C summing junction boxes, are equipped with a 25 pin
Sub-D connector, which provides a quick reliable connection to the Model 1006
LC System Tester with standard Cable “A”.
In order to use the LC System Tester on weighing systems using summing
J-boxes other than the CGS4/C or CEM4/C, we are offering our customers
a free evaluation for installing a 25 pin Sub-D connector on their own summing
junction boards.
If you would like to take advantage of this offer, we would require detailed
drawings or a sample of the summing J-Boxes that you are currently using.

6 Selection of the Display division value
Display Division Value
0.1
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.

mV/V signal generated by the LC Tester and sent to the instrument.
The and keys allow to generate the signal output (in steps of 0.1 mV/V) over a
range from 0 to FS.
The mV/V Full Scale value corresponds to the average of the individual mV/V load cell
sensitivities programmed in the “WEIGHING PARAMETERS” menu. See page 16.
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.
Percentage of signal output referred to the Full Scale.
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.
