Features: - 3 5/6 bit resolution, clear LCD screen with backlight, data hold function. Mini size, portable to carry. - BT Multimeter + Data Logger + Temperature Meter. Widely used in electrical testing, automotive repairing, industrial temperature measuring, etc. - With auto ranging and manual selection, supports measuring AC DC voltage, AC DC current, resistance, capacitance, frequency, continuity, diode and duty cycle. - Supports NCV non-contact voltage detection; the LED above the display will glow, and the meter will beep when AC voltage is detected. - True RMS test supported, 5999 counts, high accuracy, easy operation. - BT 4.0 wireless transmission, more stable, less power consumption. Supports BT function in smartphone APP and PC software, compatible with Android 4.3 and above/ iOS 7.0 and above/ Wins. - BT recording function can be applied to a variety of scenarios, such as long-time data detection, high-risk test environment, narrow environment detection, multiple groups of data need to be recorded at the same time, etc. - Real-time measuring and auto data logging, chart and diagram mode helps to analyze the data tendency. - Offline record function allows you to record for a long time without staff on duty, while reducing BT consumption to conserve the battery power of the multimeter. - Powered by 2 AA batteries (not included), auto power off in about 30 minutes to save power.
