    Automatic input/output testing (Program sweep)

    The Yokogawa CA550 is an advanced piece of equipment that offers automatic input/output testing for calibrations targets. This product is perfect for those who need to save time and ensure accurate results. The CA550 main unit saves calibration results, such as the generated value, measured value, error rate, date/time, and pass/fail in CSV format. In addition, the CA550 can be connected to a PC using a standard USB cable. It can also be used as a mass storage device, making it easy to transfer data to the PC.

    Easy-to-view Display

    The CA500 has a Reflective LCD, which provides improved outdoor visibility. With a main display for generated/measured values and a sub display for %, mV, Ω, etc. the CA550 allows you to quickly and easily confirm all the information you need at a work site.

    Wiring information displayfunction

    This innovative device allows you to see a wiring diagram displayed according to the function you’ve selected, making it easy to ensure that you’re connecting everything correctly. This prevents the risk of mis-wiring and makes your job much easier overall.

    Thermocouple generation using TC Mini Plug

    Using a TC Mini Plug together with a compensating lead wire enables generation of thermal electromotive force without an external RJ sensor.*

    * A compensating lead wire needs to be prepared by customer.

    Easy-to-use key operation  – 0%/100% keys

    The source can be easily switched between 0% and 100% of range.

    Users can also set a desired value.

    UP/DOWN keys

    The output is changed in preset steps by pressing UP or DOWN key.

    Operation key layout

    Keys related to generation and measurement are arranged collectively to allow easy and intuitive operation.

    SQUARE ROOT output

    For 4-20 mA, 1-5 V ranges, users can choose between LINEAR and SQUARE ROOT output.
