394B

394B is a 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 current loop applications in process control systems. Source and simulate industry standard 0-20mA and 4-20mA control loops using the adjustable DC current output. To evaluate process transmitters, the built-in power supply outputs 24V while measuring the signal drive current displayed in mA and % of scale. Additionally, the 394B serves as a general purpose multimeter delivering the performance required for evaluating a wide range of electronics and electrical systems.

• Adjustable manual and automatic output current ramp and step modes
• HART mode inserts 250 Ω resistor in series with loop power o/p when evaluating devices using HART
• Measurement functions: DCV, ACV, AC+DC, DCI, ACI, resistance, frequency, continuity, diode test
• 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
• HFR mode applies a LPF for AC measurements (800Hz cut-off), frequency measurement to 100KHz
• Dirt and water-resistant housing with rubberized protective case
• Isolated USB interface with operating software for remote data logging
• CAT III 1000V / CAT IV 600V protection
