Ana Özellikler
Meter, Scope and Automotive Signal Tools
True RMS Auto-Ranging Multimeter
Measures DC / AC voltage, current, resistance, diode, and frequency. Auto range helps reduce manual range selection, while True RMS improves reading reliability for electrical testing.
Osiloskop Modu
The product page lists 500 kHz analog bandwidth, while the current model PDF lists 200 kHz. Confirm the delivered hardware, firmware and manual version before choosing DM303 for a bandwidth-dependent task; neither figure is the sampling rate.
Automotive Circuit Test
Supports automotive circuit voltage and drive-current checks. It can help check battery voltage, vehicle circuits, ECU-related wiring, and other electrical parts through the proper test leads.
Injector And Relay Test
DM303 lists drive and observation modes for supported electromagnetic injectors, excluding 120 V injectors, plus relay testing. Confirm component type, pinout, supply, current and permitted output mode; never drive an ECU output, SRS, data line or unknown module.
Analog Signal And K/CAN Line Data
The listed outputs are 5 V square, 5 Vpp sine and 12 V square. Use them only on a documented permitted load and pin after confirming source impedance/current limits for the delivered version; do not inject into powered data lines, ECU outputs, SRS or unknown modules. K/CAN observation is not a full vehicle scan.
Dedicated Automotive Test Modes
DM303 adds injector, relay, cranking, signal simulation, and K/CAN line checks to multimeter and oscilloscope functions. Injector testing does not support 120V injectors.
Color Screen, Multiple Languages
The brightness-adjustable 2.8-inch color screen presents test menus in multiple supported languages, including English, French, Spanish, German, and Chinese.
Portable Electrical Test Kit
The toolbox stores DM303 and its test leads together for transport and organized storage.
Flexible Battery Setup
Use compatible dry batteries or an optional compatible lithium battery, purchased separately. Only the rechargeable lithium battery option may be charged through the device.
Handheld Controls And Connections
DM303 brings its display, navigation keys, and separate measurement inputs into one handheld unit with a rear stand.
3 Yıl Garanti Desteği

Güvenli Kullanım
Control Output, Bus and Input Connections
Limit Active Output
Injector drive and 5 V square, 5 Vpp sine or 12 V square outputs require a documented permitted pin and load. Output amplitude alone does not define safe current, impedance or duty for an unknown circuit.
Kuru Pil Seçeneği
You can install 4pcs 1.5V dry batteries for normal use. Do not charge dry batteries through the device.
Charge Only Lithium Setup
If a compatible rechargeable lithium battery is installed, it can be charged. Dry batteries must not be charged.
Piller Dahil Değildir
DM303 / DM301 is shipped without batteries due to shipping and battery restrictions. Batteries need to be purchased separately.
Lityum Pil Seçeneği
You may install a compatible lithium battery by yourself. The reference image shows a 503450 3.7V 1000mAh lithium battery style.
Sonucu Bağlam İçinde Yorumlayın
Keep measurement, waveform, protocol observation and active output as separate modes. A meter fuse or input rating does not authorize power or signal injection into an ECU, SRS circuit, sensor or data line.
Sonuç Kılavuzu
Sonraki adıma karar vermeden önce sonucu okuyun.
Marş Testi
During vehicle starting, a minimum battery voltage above 9.6V is generally considered normal. If the value drops below 9.6V, the battery may be aging or weak.

Alıcı Soruları
Elektrik Bağlantısı ve Ölçüm Soruları
Mı AUTOOL DM303 Piller Dahil mi?
No. DM303 / DM301 is shipped without batteries. You need to buy batteries separately. You can use 4pcs 1.5V dry batteries, or install a compatible lithium battery setup by yourself.
Can I Charge Dry Batteries Inside DM303?
No. Do not charge dry batteries. Only a compatible rechargeable lithium battery setup can be charged. If you are not sure whether your battery is rechargeable or compatible, contact AUTOOL Store before charging.
What Lithium Battery Style Is Shown For DM303?
The reference image shows a 503450 3.7V 1000mAh lithium battery style. Confirm the connector, size, and compatibility before installing a lithium battery.
DM301 ve DM303 Arasındaki Fark Nedir?
DM301 focuses on basic measurement functions such as voltage, current, resistance, frequency, oscilloscope, and ignition pulse signal testing. DM303 adds more automotive diagnostic functions, including fuel injector testing, relay testing, automotive circuit testing, cranking test, signal simulation, CAN line data reading, and K/LIN-related line data reading.
Does DM303 Support Injector Testing?
Yes. DM303 can drive supported electromagnetic injectors, including supported GDI injectors, and can detect real-time injector signals; it does not support 120V injectors. Confirm injector type, pinout, supply, current, and the vehicle procedure before output. A drive response does not by itself prove spray pattern, flow, or root cause, and active output must stay off ECU outputs, SRS circuits, powered data lines, and unknown modules.
What Does The Cranking Test Result Mean?
During vehicle startup, DM303 records the minimum battery voltage and uses 9.6V as a general reference. A lower reading can indicate a weak or aging battery or a starting-system issue that needs further inspection. Apply the battery maker or vehicle procedure for the battery type, temperature, and state of charge.
What Measurement Ranges Does DM303 Support?
The page lists DC 0–1000V and AC 0–700V voltage, 0–20A and 0–200mA current, 0–1MΩ resistance and 1Hz–1MHz frequency ranges. The manual distinguishes 20A maximum from 10A continuous current. These values remain subject to the selected terminal, mode, probe and CAT conditions.
Can DM303 Replace A Full Vehicle Diagnostic Scanner?
No. DM303 is an automotive diagnostic multimeter and circuit / signal testing tool. K/CAN line data reading helps with circuit-level diagnosis, but it should not be described as a complete vehicle diagnostic scanner.
Pakete hangi aksesuarlar dahildir?
Package contents: DM303 main unit, user manual, retail box, portable toolbox, multifunction test lead, battery clip cable, multimeter probes, jumper / adapter cables, and additional test leads. Batteries are not included.
Which Languages Does DM303 Support?
DM303 supports a multi-language interface, including English, French, Portuguese, Polish, Spanish, Japanese, Russian, Italian, German, Dutch, Korean, Chinese, and other supported firmware options. If a specific language is required, confirm before ordering.

I’ve been using the DM303 multimeter and it’s been a great help.
I’ve been using the DM303 multimeter and it’s been a great help. The 2.8-inch color screen is clear and easy to read in different working conditions. The oscilloscope works well for checking automotive signals, and the auto range and true RMS make measurements accurate. It comes with plenty of test cables, supports multiple languages, and the plastic toolbox keeps everything organized and protected. Very reliable for auto repair work.
