1000 V CAT III / 600 V CAT IV; current terminal shutter
Fits process loop work where you need a Yokogawa CA450 combining a True-RMS DMM with 24 V loop power, 0.05% DC mA accuracy, and span/step/simulate sourcing.
Key advantages
- Loop — 24 V loop power with selectable 250 Ω HART/BRAIN
- mA accuracy — DC mA 0.05% / 30.000 mA
- Source — 4–20 mA span/step/auto-step/sweep; SIMULATE (SINK)
- DMM — True-RMS V/I/Ω/frequency/continuity/diode
- Safety — 1000 V CAT III / 600 V CAT IV; current terminal shutter
Typical applications
- Transmitter loop power and simulation.
- HART/BRAIN 250 Ω selection in-loop.
- Field DMM plus process calibrator in one tool.
Selection guide
- Loop tasks — Source vs simulate vs measure
- HART/BRAIN — 250 Ω resistor use
- Sensor mode — Scaled dual-display readout
- Comms — Optional IR-USB package
Common mistakes
- Forgetting 250 Ω when HART communicators need it.
- Using simulate without external loop power correctly.
- Exceeding CAT ratings.
When to RFQ / what to tell us
