Intelligent Multimeter with Multiple Functions: measures AC/DC current, AC/DC voltage, resistance, capacitance, temperature, frequency, continuity, and diode test, with non-contact voltage detection. Flashlight Function: provides auxiliary lighting for low-light or dark environments; automatically turns off after approximately 1 minute.NCV Non-contact Voltage Detection: place the NCV sensor near the cable to detect voltage presence. Detects AC voltage at 90V and above; when voltage is detected, the buzzer alarms and the LCD analog bar displays signal strength.Safety Operation: built-in overload protection fuse, smart anti-burn design. Complies with DC/AC 600V Category III overvoltage standard and features double insulation protection. Smart Touch Screen Control: easy to operate with color reverse LCD display for clear data viewing.Compact and Accurate: small size similar to a mobile phone, portable and convenient to use. Equipped with high-performance chip for accurate measurements.Silicone Protective Case: includes silicone case to protect the device from drops and scratches during use in various conditions.Specifications: AC Current: 999.9mA / 10A DC Current: 999.9mA / 10A AC Voltage: 999.9mV / 9.999V / 99.99V / 999.9V DC Voltage: 999.9mV / 9.999V / 99.99V / 999.9V Resistance: 999.9 ohm / 9.999K ohm / 99.99K ohm / 999.9K ohm / 9.999M ohm / 99.99M ohm Capacitance: 9.999nF / 999.9nF / 9.999uF / 99.99uF / 999.9uF / 9.999mF / 99.99mF Temperature: -40C to 1000C (-40F to 1832F) Frequency: 100Hz / 1000Hz Working Altitude: up to 2000m Display: LCD Maximum Display: 9999 digits Polarity Indication: Automatic, "-" indicates negative Overrange Display: "OL" or "-OL" Sampling Rate: Approximately 3 times per second Auto Power Off: 15 minutes Battery Low Indicator: Yes Temperature Coefficient: less than 0.1X accuracy per C Operating Temperature: 0C to 40C Storage Temperature: -10C to 50C Power Supply: Built-in 3.7V 600mAh polymer lithium battery Product Dimensions: 133 x 66.5 x 22.5mm / 5.24 x 2.62 x 0.89in Product Weight: 162g / 5.71oz Color: Red Material: ABS Package Contents: 1 x Multimeter 1 Pair x Test Leads 1 x Thermocouple 1 x USB Type-C Cable 1 x English Manual Note: Light and screen display differences may cause slight color variation between the image and actual item.
