4. Calculate the compensating resistance:
Use the following formula:
R
co
Determined compensation resistance, to be connected in the signal cable SIG+
R
Output resistance of the load cells; can also be measured under load
L
e
Weight error: Differential value from the lowest weight value
L
t
Test load; placed on all four corners
N
L
Number of load cells in the scale
Figure 6-3 Formula for corner load adjustment
Example calculation:
LC 1: R
comp
= R1 = 1004.52 Ω x 12 kg /
approx. 80 Ω
LC 2: -

LC 3: R
comp
= R3 = 1010.70 Ω x 7 kg /
approx. 47 Ω
LC 4: R
comp
= R4 = 1028.12 Ω x 4 kg /
approx. 27 Ω
