Supplier of Yokogawa CA500 Series Multi-Function Process Calibrator
Accurate and Versatile Calibration for Process Instrumentation
The Yokogawa CA500 Series Multi-Function Process Calibrator is a high-performance portable calibration instrument designed to simplify the testing, calibration, and maintenance of process control devices. Built for field technicians, maintenance engineers, and calibration professionals, the CA500 Series provides highly accurate sourcing and measurement capabilities for a wide range of process signals, helping ensure the reliability and accuracy of industrial instrumentation. The series includes the CA500 and CA550 models, offering different levels of precision to meet various calibration requirements.
Key Features
Multi-Function Signal Generation and Measurement
The CA500 Series can source and measure multiple process signals, including:
- DC Voltage
- DC Current
- Resistance
- Thermocouples (TC)
- RTDs (Resistance Temperature Detectors)
- Frequency Signals
- Pulse Signals
This versatility allows a single instrument to replace multiple calibration tools, improving efficiency during field maintenance and commissioning.
High Accuracy Calibration
Designed for demanding industrial environments, the CA500 offers measurement accuracy up to:
- 0.015% for DC current
- 0.020% for resistance
- 0.3°C for RTD measurements
The higher-performance CA550 model provides even greater accuracy for critical calibration applications.
Advanced Sweep Functions
The CA500 Series supports multiple output patterns for automated testing:
- Linear Sweep
- Step Sweep
- Program Sweep
These functions allow users to simulate process conditions and verify instrument response quickly and accurately.
Easy-to-Read Display
A reflective LCD display provides excellent visibility in both indoor and outdoor environments. The dual-display layout allows users to view generated and measured values simultaneously, improving workflow efficiency during calibration tasks.
Wiring Guidance Function
Built-in wiring diagrams are displayed based on the selected function, helping technicians perform connections correctly and reducing the risk of wiring errors during field calibration.
HART Communication Support (CA550)
The CA550 model includes HART communication capabilities, enabling users to:
- Read transmitter information
- Configure LRV and URV settings
- Perform loop tests
- Trim analog outputs
- Verify smart field devices
This functionality simplifies the maintenance of modern intelligent transmitters.

Applications of Yokogawa CA500 Series Multi-Function Process Calibrator
20 mA SIMULATE
The CA500 series 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. DC mA signal measurement and zero-point check can be performed with an accuracy of 0.01% of reading (0.015% of reading for CA500).
Zero point adjustment of HART transmitter
CA550 supports HART communication (Universal command/Common practice command).
Reading of HART device information, writing of LRV/URV, and trimming of analog output are possible.
TC SIMULATE
The CA500 series 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/CA550, as it can measure output signals.
RTD SIMULATE
CA500/CA550 corresponds to 14 types of RTD for sourcing. It achieves a high basic accuracy of 0.1°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
This 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.
