Review: Been working out well so far. - UPDATE: The ignition pulse mode is a neat feature and nice for use in small engine diagnostics, one for setting engine rpm using the rpm readout and picking up on a weak coil reading the voltage signal. This comes after collecting some of your own data over time as I cant say as I've seen any manufacturer give any specs like this on coils. -I dip into all sorts of repair from small engines to power sports to automotive. For the price and for my budget so far this tool has been a good investment. The power probe feature is nice, done a few parasitic draw diagnostics with it and today verifying some cheapo o2 sensor's function before installation. It makes voltage drop testing a breeze also. hopefully we e are going to use it to control the heater on a different wideband O2 sensor in an attempt to make a portable A/F sensor. Need to check and see if it's capable to support that first though as to not burn up the meter which I believe has breakers that reset. Not sure on that. Update: Ignition
Review: Great automotive meter - I bought this meter for the scope function, and it is great . I love the fact that it has all I need in the box .. my go to box for quick electrical diagnostics before pulling out the pico or ats , It has a similiar power probe function . It also has amp meter and ohm meter , but the great part for me is the scope function . I can check signals to see if they are there before digging deep . Also it adjust the time base and the voltage scale . Great meter well worth it and the price is the good part too thanks autool

## 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.

### ⭐⭐⭐⭐⭐ Works good so far
*by K***D on February 27, 2025*

Rechargeable internal battery using USB C, has worked as good as any of my other meters so far. I haven't had the opportunity to try any of the other features on it other than the volt and ohm functions, but both of those work well.
