      • 1) The surface of a measuring wheel is subject to wear. This depends on contact pressure, acceleration behavior in the application, traversing speed, measurement surface, mechanical alignment of the measuring wheel, temperature, and ambient conditions. We recommend you regularly check the condition of the measuring wheel and replace as required.
      • 2) Allow for self-heating of 3.3 K per 1,000 rpm when designing the operating temperature range.
