Data Sheet The 390B Series True RMS multimeters offer a comprehensive solution for general purpose measurement applications. Bundled with a complete set of accessories, these multimeters provide technicians and engineers with accurate results, data logging capabilities, and measurement features for evaluating a variety of electronics or electrical systems. The easy to read display features an analog style bar graph to help identify measurement trends or fluctuating signals. When working in low-light environments, the auto on/off backlight adjusts for best visibility while maximizing battery life. Dual line display capabilities enable two measurements or one measurement and a math function to appear on screen simultaneously. Advanced features like data logging records measurements to the meter's internal memory at a user-specified sampling interval. Model 390B features wireless connectivity for logging measurement data directly to a smartphone or tablet while in the field. All models in this series provide convenient measurement monitoring and recording from a PC connected to the meter's optical isolated USB interface. Additionally, measurements stored in the meter's internal memory can be exported using the provided PC application software. Features and benefits ■ Measurement functions: DCV, ACV, AC+DC, DCI, ACI, resistance, capacitance, frequency, diode, temperature, & continuity test ■ True RMS AC and AC+DC measurements ■ Up to 100,000-count, dual display with analog style bar graph ■ Temperature measurements using provided K-type thermocouple ■ dB, dBm, limits, peak-hold, REL (A), MIN, MAX, and average math functions ■ AutoV/LoZ mode automatically switches between AC or DC voltage measurements* ■ HFR (High Frequency Rejection) mode applies a low pass filter for AC measurements (800 Hz cut-off) ■ Bluetooth connectivity offers live data monitoring and logging from a mobile device* ■ CAT III 1000 V / CAT IV 600 V protection ■ Dirt and water-resistant housing with rubberized protective case ■ Isolated USB interface with operating software for remote data logging *Model 390B only Technical data subject to change © B&K Precision Corp. 2023
