Frequently Asked Questions (FAQ)

1. What instruments can be calibrated using the Yokogawa 2560A?

The Yokogawa 2560A is engineered to calibrate a wide variety of electrical and temperature measuring instruments, including handheld and benchtop digital multimeters (DMMs), analog and digital panel meters, power transducers, data loggers, and temperature transmitters.

2. How does the parallel current expansion feature work up to 73.44 A?

The instrument features a master-slave parallel connection capability. By linking two Yokogawa 2560A units together using dedicated communication cables, you can combine their output capacities. This configuration allows you to source up to 73.44 A of DC current, making it ideal for testing high-current shunts and heavy industrial power meters.

3. Does the Yokogawa 2560A support direct thermocouple simulation?

Yes, it supports 10 industry-standard thermocouple types (including R, S, B, J, T, E, K, N, C, and A) as well as user-defined curves and RTDs like Pt100. It also features built-in Reference Junction Compensation (RJC) to ensure accurate temperature measurements without requiring external compensation setups.

4. Is this calibrator suitable for automated test equipment (ATE) systems?

Yes. The Yokogawa 2560A comes equipped with standard communication interfaces such as USB and GPIB, allowing it to integrate smoothly into automated test racks and computer-controlled calibration software environments.

5. What is included with the purchase, and are calibration certificates available?

Every unit ships with standard manufacturer accessories. For details regarding factory calibration certificates or accredited ISO/IEC 17025 calibration options to meet your facility’s compliance standards, please reach out directly to our sales team.
