The active Straingage R3 and R4 are connected to the terUs,
+Ud and -Us.
HBx: The solder bridges “8”, “19”, “30” or “41” must be closed so that the
internal extension resistors R1 and R2 are activated.

The active Straingage R4 is connected to the terUd, AUX and
-Us in 3-wire technology.
HBx: The solder bridges “8”, “19”, “30” or “41” must be closed so that the
internal extension resistors R1 and R2 are activated.
A solder bridge should be set depending on the Straingage resistance
(120/350/1000 Ohm), e.g. 120 Ohm at channel 1: Solder bridge 11
(vertical); 350 Ohm at channel 2: Solder bridge 21 (horizontal).
