Calibrators
Calibrators are used to validate and adjust the accuracy of test instruments, which can deteriorate over time due to many factors, including environmental and process conditions. Calibrators ensure that the test equipment continues to perform accurate measurements within acceptable tolerance.

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)
