Yokogawa CA450 Features:
- Loop check functions
- Simultaneous 24 V loop power and mA measurement
- HART/BRAIN mode setting with loop power (Adds 250 ohm resistance internally
- Generation functions – SIMULATE (SINK) function simulates transmitters– 4-20 mA span/step/auto-step/sweep output
- Measurement functions
- – 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
- Enhanced Safety—helps eliminate electric shocks – 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.*1 – Measurement categories 600 V CAT. IV, 1000 V CAT. III
- Linking with a PC
- DMM Communication Package can be used to save and
- Loop check function
- Span generation function
- Step generation function
- Sweep generation function
- AC/DC Current measurement (SENSOR mode
