Yokogawa Process Multimeter CA450 test instrument 

The Yokogawa Process Multimeter CA450 is a portable test instrument that combines a digital RMS multimeter and a loop calibrator, allowing process technicians to efficiently perform their tasks using a single tool. The Yokogawa CA450 provides 24-Volt loop power, reducing the need for carrying a separate power supply when performing transmitter testing. And with its built-in, selectable 250-Ohm Hart resistor, it also eliminates the need for a separate resistor. 

Technicians involved in industrial process maintenance must troubleshoot a variety of instrumentation in the field. This necessitates carrying a wide variety of tools and electrical equipment such as digital multimeters and calibrators/sorucing devices. Individual, single purpose devices may not have the varied functionality needed for equipment validation, in addition to being cumbersome and inefficient to carry. In these situations, a device that can  source, measure, and have PC compatibility would be the perfect instrument for the task. The CA450 Process Calibrator is defined by:

Varied Functionality

Source commonly used field instrumentation standards such as loop power, and miliamps DC

Measure like a DMM; capture and log current, voltage, resistance, and even DCS power 

Step/Sweep outputs for enhanced testing of field equipment

PC communication for traferring and saving data

Enhanced Safety

Prevent polarity error issues with terminal safeguards to prevent incorrect wiring

Conforms to 600V CAT. IV and 1000V CAT III
