Features:

Process

• Source/Measure/Simulate 0-20 mA and 4-20 mA DC current
• Simultaneously monitor mA and % of scale
• Adjustable manual and automatic output current ramp and step modes
• Built-in 24 V loop power supply eliminates the need for an external supply
• HART mode inserts 250 ohm resistor in series with loop power output

General Purpose

• DCV, ACV, AC+DC, DCI, ACI, resistance, frequency, continuity measurement functions
• True RMS AC and AC+DC measurements
• 50,000-count, dual display
• dB, dBm, limits, peak-hold, REL (delta), MIN, MAX, and average math functions
• Isolated USB interface with operating software
• HFR (High Frequency Rejection) mode
• Dirt and water-resistant housing with rubberized protective case
• CAT III 1000 V / CAT IV 600 V protection

The 394B Process Multimeter combines the capabilities of a mA loop calibrator with a full-featured True RMS multimeter in one package. Dedicated mA loop calibrator functions provide technicians and electricians with the tools required for testing and troubleshooting process control systems. Source and simulate industry standard 0-20 mA and 4-20 mA control loops using the adjustable DC current output.
