The Yokogawa CA450 Process Multimeter 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:
