CA450 Process Multimeter
Brand: Yokogawa Electric CorporationThe 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.
Features- 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
- Prevent polarity error issues with terminal safeguards to prevent incorrect wiring
- Conforms to 600V CAT. IV and 1000V CAT III
