The Yokogawa CA500-F1/TE Multi-Function Process Calibrator is a high-performance calibrator designed for use in multiple applications. The CA500 offers useful functions for field work and provides improved source and measurement accuracy, sufficient for calibrating field instruments with higher accuracy and confidence.

Easy-to-view Display

The CA500 features a Reflective LCD, providing improved outdoor visibility. The main display (generated/measured values) and Sub display (%, mV, Ω, etc.) allow required information at a work site to be confirmed at a glance.

Wiring information display function

A wiring diagram is displayed according to the function selected. This function allows a user to perform wiring while referring to a wiring diagram and prevents mis-wiring.

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.

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.

Applications

20 mA Simulate

The CA500 can be used as a transmitter simulator to perform a loop test. It sinks the set current from an external voltage source of instrumentation equipment.

Two-wire Transmitter Loop Check

DC mA signals can be measured by supplying power to the transmitter from a 24 V DC power supply (not included). DC mA signal measurement and zero-point check can be performed with an accuracy of 0.015% of reading.

TC Simulate

The CA500-F1/TE corresponds to 17 types of TC for sourcing. It achieves the high basic accuracy of 0.5°C (typical of type K), two times better than the previous model. Also, input/output testing is possible with a single CA500, as it can measure output signals.

RTD Simulate

The CA500 corresponds to 14 types of RTD for sourcing. It achieves the high basic accuracy of 0.3°C (typical of type Pt100), which enables it to operate a highly reliable test. Additionally, input and output testing of temperature transmitters is possible at the same time.

Pulse Simulate

The calibrator performs measurement of pulse signal integration from a flowmeter and generates a pulse to a receiver, such as integrating counter or pulse converter. Integration time can be set from 1 min to 60 min.
