Yokogawa 2558A – Precision AC Standard

  • Intuitive operation
    Dials and switches are provided for each digit and function, and traditional 7-segment LEDs provide clear visibility
  • 6 voltage ranges (100 m/1/10/100/300/1000 ([V])
    4 current ranges (100 m/1/10/50 ([A])
  • Sweep (Voltage/Current/Frequency)
  • Output Divider
    Linearity tests can be simply performed by dividing the output into steps. For example, a setting of 4 will generate steps of 25, 50, 75 and 100% of the set output value.
  • % Deviation readout
  • Common current output terminals
    The same output terminals are used for all current ranges. Test times are therefore reduced by avoiding the need to change the wiring for meters which have different ranges.
  • Wide frequency range-: 40 to 1000 Hz (Frequency accuracy : ±50 ppm)
