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.
