Characteristics: Full-featured Multimeter: The professional multimeter has various useful functions to measure DC / AC voltage, DC / AC current, resistance, capacitance, frequency / load, temperature and diode test, continuity test, non-contact AC voltage detection, live wire detection. Temperature measurement: wide measurement range -40 1000 / -40 1832 , use the included K-type thermocouple probe to test the temperature of the target object, switchable unit / . Smart Measurement (AUTO): This measurement mode is the default when powered on. In this mode, you can measure DC / AC voltage, resistance, continuity, and the meter can automatically identify the measurement signal. Maximum / minimum and relative value measurement: in manual mode, it can measure the maximum and minimum value (incorrect capacity, frequency / duty cycle, temperature, NCV / gear energized) and relative value (incorrect in continuity, frequency / duty cycle, temperature, NCV /Live). Flashlight and Data Hold: Secondary highlights work areas in low light conditions, and you can press the data hold button to keep the measured value unchanged to save it alone. Portable Pocket Size: Compact design is comfortable to carry, wrapped with a rubber sleeve to protect the multimeter after falling from height. Material: ABS Display: 9999 counts Sampling rate: Approx. 3 times / second Display out of range: "OL" Environment Operating conditions: CAT.IV 600V, CAT.III 1000V, pollution level 2, altitude <2000m Working temperature and humidity: 0 40 (<80% RH, <10 non-condensing) Storage temperature and humidity: -10 60 (<70% RH, take out the battery) Product size: 165 * 83 * 23mm / 6.49 * 3.27 * 0.91in Product weight: 249g / 8.80oz Package weight: 467g / 16.48oz Package size: 20.3 * 10.7 * 5cm / 7.99 * 4.21 * 1.97in
