Yokogawa CA450 Portable Process Multimeter Combine Digital RMS Multimeter and Loop Calibrator
The Yokogawa CA450 Process Multimeter is a portable test instrument to combine a digital RMS multimeter and a loop calibrator to give process technicians the same functionality in one 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. Process technicians can now do the same job while carrying less equipment.

Description of Yokogawa CA450 Portable Process Multimeter Combine Digital RMS Multimeter and Loop Calibrator
The Yokogawa CA450 process multimeter is an on-site measuring instrument that combines the functionality of a digital multimeter for basic measurements such as voltage, current, and resistance, with a 4-20mA loop calibrator for electrical and process measurements. With specialized functions for repair, maintenance, and troubleshooting of plant equipment, the Yokogawa CA450 is a single-unit, on-site measuring solution that reduces the engineering load and improves plant efficiency by accomplishing tasks that have traditionally required two on-site measuring instruments.
The CA450 is a true RMS digital multimeter with a basic accuracy of 0.05% and dedicated sensor modes for direct inputs from sensors such as AC/DC clamp probes. In addition, the meter incorporates a number of process-related features including loop check and 4-20 mA output generation and measurement functions.
With the loop check function, designed for tests on 2-wire transmitters, the CA450 supplies 24 VDC power to the transmitter and measures the DC output in milliamperes to an accuracy of 0.05% up to 30 mA. A HART mode with loop power and 250 ohm resistance allows HART and BRAIN communications to be tested. A transmitter simulator function allows transmitter I/O to be checked by drawing in ('sinking') designated currents from the external voltage generators of the instrumentation. The 4-20 mA generator output includes span, step, auto-step and sweep capabilities.
The CA450 can also be used to carry out operating checks and adjustments on valve positioners, including zero span adjustment, response testing using the auto-step function, and tests for hunting, sticking/slipping and valve open/close errors. Controller programs can also be verified using the CA450's 4-20 mA step generation function, which switches between 4 and 20 mA in 4mA output steps.
Electrical measurements include power supply peak-to-peak measurement with instantaneous detection in the DC voltage measurement mode, and AC/DC current measurement up to 180 A AC and 3000 A AC in sensor mode. The CA450 can also be used to check panel meters for correct connection, reproducibility and errors. The CA450 features a safe design with current terminal shutters to protect both the operator and the instrument against incorrect connection. It conforms to the 600 V CAT. IV and 1000 V CAT. III standards. An optional adapter allows the instrument to be linked with a PC, with data transferred via an infrared USB interface.
