      • 1) These values were measred at an ambient temperature of 25 °C. There may be variations at other temperatures.
      • 2) A cycle consists of the wire being pulled out and drawn in.
      • 3) The service life depends on the type of load. This is influenced by environmental conditions, the installation location, the measuring range in use, the traversing speed, and acceleration.
