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.
Simultaneous 24 V loop power and mA measurement
HART/BRAIN mode setting with loop power
(Adds 250 ohm resistance internally)
SIMULATE (SINK) function simulates transmitters
4-20 mA span/step/auto-step/sweep output
High accuracy signal measurement:DC mA 0.05%/30.000 mA
Handheld DMM function
Peak Hold function for the peak voltage measurement of DCS power supply
Dedicated sensor modes for direct reading of many sensor signal types
Current terminal shutter prevents incorrect connections
1 A or more of AC/DC current can be read directly using the optional clamp probe and scaling in SENSOR mode.
Measurement categories 600 V CAT. IV, 1000 V CAT. III
