Description
Combines a mA loop calibrator with a full-featured True RMS multimeter in one package
Source/Measure/Simulate 0-20 mA and 4-20 mA DC current
Simultaneously monitor mA and % of scale
Built-in 24 V loop power supply for testing process transmitters without an external supply
DCV, ACV, AC+DC, DCI, ACI, resistance, frequency, continuity, diode test measurements
Process Multimeter
The 394B Process Multimeter combines the capabilities of a mA loop calibrator with a full-featured True RMS multimeter in one package.
A Dedicated mA loop calibrator function provides technicians and electricians with the tools required for testing and troubleshooting current loop applications in process control systems. Source and simulate industry standard 0-20 mA and 4-20 mA control loops using the adjustable DC current output.
Additionally, the 394B serves as a general-purpose multimeter delivering the performance required for evaluating a wide range of electronics and electrical systems.
