Does the DynEx need re-calibrated periodically?
Answ: No, the electronic load cells avoid the problem of air seepage into the hydraulic system, or leakage at the hydraulic seals. The electronic cells are stainless steel beams with strain gauges attached to these beams. The strain gauges either work or they do not. There is no drift or change in characteristics of the strain gauges or the steel beams unless subjected to unusually high stresses of temperature or mechanical impact. Should this occur, the microprocessor would detect this damage at turn-on and an Error Message is displayed indicating the device is damaged.
