4.5.6 Testing the measuring circuit
A simple test with the load cells connected can be carried out with a multimeter.
Note:
With external supply or use of an intrinsically safe load cell interface the internal load cell
supply is not relevant.
Measuring voltage
0–12 mV = @ LC with 1.0 mV/V
0–24 mV = @ LC with 2.0 mV/V
4.5.7 External supply of the load cells
If the total resistance of the load cells is ≤75 Ω (e.g., more than 4 load cells with 350 Ω),
an external load cell supply is required. In this case, the internal supply is replaced by a
potential-free external supply.
The center of the external supply voltage (0 ext. supply) should be connected to GNDA to
ensure that the voltage reacts symmetrically to 0.
The internal supply is not connected.
