  • Page 5: Application And Meter Design

    1. APPLICATION AND METER DESIGN The programmable digital panel meter N30O is destined for measu- rements: number of pulses, frequency, period, worktime, encoder position. Additionally, the meter enables the indication of the current time. The readout field is a LED display, which allows the exposition in colours: red, green and orange.

    3. BASIC REQUIREMENTS, OPERATIONAL SAFETY In the safety service scope, the N30O meter meets the requirements of the EN 61010-1 standard. Mentioned below applied symbols mean: - especially important, one must acquaint with this information before connecting the meter. The non-observance of notices marked by this symbol can occasion injures of the personnel and a damage of the instrument.

  • Page 31 Fig. . Individual Characteristic During the function approximation, one must remember that for the ap- proximation of functions strongly differing from the linear characteristic, higher the number of linearizing segments, smaller the error related to the linearization. If measured values are smallest from H1 then, recalculations will be made on the base of the first straight line calculated on the base of po- ints (H1, Y1) and (H2, Y2).
