  • Three current inputs support closed link testing
  • Logic gate control to keep potential away from the operator, as well as a case ground terminal

    • Description:
    The MA-10 watthour standards are rugged, portable and specifically designed to test watthour meters, using the comparison method, in the field or the laboratory.

    The MA-10 standards are engineered to meet the most stringent quality measurements in regard to accuracy, stability and reliability. They are one of the top selling, most accurate standards available.

    Applications:
    The standards provide a true watthour display with a Kh of 1 for the entire operating range. This feature allows for a much simpler percent registration calculation.

    The MA-10 series are totally autoranging on the potential input, current input and auxiliary power input. Totally autoranging inputs make it impossible to damage the unit by applying a signal to the wrong input. The three summing current inputs can be used to perform closed link testing.
