For amplifiers MX840B, MX440A and MX410B, we recommend this connection
technique for very small measurement ranges, particularly in environments
subject to interference and when using long cables.
This applies for all bridge connections.
With cable lengths >50 m, a resistor with half the value of the bridge resistance
(RB/2) must be connected in each sense lead of the transducer.
