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.
