## Description

AUTOOL Automotive Multimeter Oscilloscope TRMS, Digital Multimeter and Oscilloscope Kit 1000V 20A, with Test K line & CAN Bus Signal, Sensor Signal, Relay Test, Ignition Pulse Signal Test

## Features

- 【More Powerful Detection Range】The multimeter can accurately measure AC/DC voltage, resistance, continuity, AC/DC current, capacitance, frequency, diodes, duty cycle and fire wire. DC voltage 0 ~ 1000V, AC voltage 0 ~ 700V, DC/AC Current 0 ~ 20A, 0 ~ 200mA, Resistance 0 ~ 1MΩ, Frequency 1 ~ 1MHZ, Continuity circuit test and ignition signal test to meet all test requirements.
- 【Oscilloscope Fuction】Waveform test bandwidth of 500KHZ, using variable sampling frequency, can measure slowly changing signal, suitable for automotive maintenance to measure and observe various signal quantities on automotive circuits, including motor drive signals, motor power voltage on electric vehicles, ignition signals, camshaft signals, crankshaft signals, wheel speed sensor signals, oxygen sensor signals, etc. of fuel car engines.
- 【Auto Range & Ture RMS】Simply select the mode and connect your leads. The multimeter will automatically select the appropriate measurement depending on what it detects. With True RMS, the DM301 portable multimeter provides you with the clear, accurate readings whenever and wherever you need them.
- 【Wiring Functions】Equipped with 8 wiring lines for different functions. They are multi-function test line, battery clip line, ignition pulse signal test line, car circuit test line, jumper and multimeter probe. The multi-function test line is used to test the battery voltage, test the fuel injector and relay, test the K-wire and CAN bus signal, test the car ECU, and test the car parts.
- 【Starting Test & Analog Signal Test】The multimeter tester can be used to evaluate the battery's starter system and determine if the 12V electrical system is producing enough power to start the engine. The multimeter also outputs 5V square wave and 5Vpp sine wave signals. Output Signal Frequency: 1Hz~10KHz Duty Cycle: 10%~90.
- 【2.8 inch Colorful Screen】Color display screen with backlight for clear reading. Built-in flashlight for dark environments. Adjustable screen brightness, button sound and sleep time to meet your various needs and various working environments, making your measurements more convenient.
- 【Three Years Warranty】For any quality problems. If DM303 has any defect, we will provide new replacement or solutions for our customers without delay, and provides lifetime technical support. For any needs, you are warmly welcomed to contact us and we will get back to you ASAP within 24 hours.
