Yokogawa 2558A - Precision AC Standard

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)

The 2558A precision DC calibrator is an easy-to-use, yet highly accurate instrument that can be used to calibrate analog power meters, thermometers, and temperature controllers that use a thermocouple or a resistance temperature detector (RTD).

The 2558A can output a wide range of AC voltages (1.00 mV to 1200.0 V) and currents (1.00 mA to 60.00 A) at frequencies of 40 to 1000 Hz. The accuracy (maximum error) is ±0.04% for AC voltage and ±0.05% for AC current, ensuring accurate calibration, and the stability is as high as ±0.005%/h. The easy-to-read digital display and dials for setting each digit are intuitive to use. The current output terminals can be used for all measurement ranges, which improves work efficiency by eliminating the need to change cables for a specific current level.
