Characteristics: Smart Multimeter with Multiple Functions: It can measure AC / DC current, AC / DC voltage, resistance, capacitance, temperature, frequency, continuity and diode test, fire wire detection. Flashlight function: additional illumination of the working area in poorly lit or dark surroundings and automatic switch-off after approx. 1 minute. Non-contact NCV voltage detection: place the NCV sensor closer to the cable being measured, and the multimeter can detect if the voltage is greater than 90ACV. When the AC voltage is detected, the meter buzzer will alarm and the analog LCD bar displays the induction intensity. Safe operation: built-in overload fuse, intelligent burn protection. Meet 600V CAT III DC / AC overvoltage standard and double insulation protection. Smart touch screen control: easy to operate, with large VA color LCD screen, convenient for quickly checking the measured data. Compact and Accurate: As small as a mobile phone, convenient to use and carry. Equipped with high performance chip to ensure its accuracy. Silicone protective case: protected by silica gel case, you can use the meter under a variety of conditions without worrying about it falling or being scratched by equipment.
