When summing a number of analog load cells to create a balance, the analog output (mV/V) and output resistance are adjusted by adjusting the resistance in the junction box. Generally, off-center placement error correction for each load cell is also performed in the junction box. With digital load cells, however, it is not necessary to adjust the output resistance and off-center placement error is digitally corrected at the indicator. This reduces calibration work and labor versus analog load cells.
