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.

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.
