• Built-in, selectable 250-Ω-HART-resistor.

Yokogawa CA450 Handheld Process Multimeter

The Yokogawa CA450 is a portable process multimeter. The CA450 test instrument combines a digital RMS multimeter and a loop calibrator to give process technicians the same functionality in one tool. The Yokogawa CA450 provides 24-V-loop power, reducing the need for carrying a separate power supply when performing transmitter testing. With its built-in, selectable 250 Ω HART resistor, it also eliminates the need for a separate resistor.
