  • 1) This value is measured at an ambient temperature of 25 °C. When the temperature changes, the value may deviate..
  • 2) The average value depends on the load pattern.
  • 3) The service life depends on the type of load. Influencing factors include: environmental conditions, installation conditions, measuring range used, moving speed and acceleration.
