AUTOOL DM103

Product Overview

The AUTOOL DM103 is a multifunctional portable digital LCR tweezer for SMD component testing, automotive circuit board repair, and electronic troubleshooting. With ±0.5% measurement accuracy, a HD OLED color display, smart component recognition, and support for resistance, capacitance, inductance, diode, and continuity testing, it helps users quickly identify components and evaluate component condition directly on high-density circuit boards.

DM103 supports three test frequencies — 100Hz, 1kHz, and 10kHz — and two effective test levels, 0.3V and 0.6Vrms. During measurement, it can synchronously display primary and secondary parameters, including RS, D, Q, Z, and X values, meeting a wider range of component diagnosis and repair needs than basic multimeters.

Key Features

Key Features

For automotive circuit board testing, the D value and Q value are important indicators for component health. DM103 helps users go beyond static capacitance or resistance readings and judge component performance more accurately.

D / Q Value Insight

Read D and Q values together with L, C, and R data to judge component condition faster and avoid basic multimeter misreads.

Auto Component Recognition

Smart recognition helps identify resistors, capacitors, and inductors quickly on dense automotive boards and SMD repair jobs.

Tweezer Form Factor

The tweezer-style probes reach tight board spaces and keep the workflow compact without changing tools.

Board-Level Repair

Synchronized primary and secondary values help technicians compare component behavior quickly during ECU board troubleshooting.

Key Features

Key Features

DM103 combines smart recognition, six test modes, OLED display, rechargeable battery power, fine gold-plated tips, and Type-C software upgrade support in a compact tweezer-style tool.

6 Test Modes

Supports automatic, inductance, capacitance, resistance, diode, and continuity test modes. Auto mode quickly identifies resistance, capacitance, and inductance without manual switching.

Primary + Secondary Parameters

Displays primary values and secondary parameters at the same time, including RS, D, Q, Z, and X values, helping users evaluate both component type and performance condition.

HD OLED Color Display

The self-illuminating HD OLED color screen provides high brightness and clear reading in bright or dim working environments.

400mAh Rechargeable Battery

Built-in 400mAh lithium battery supports up to 12 hours of continuous operation on a full charge, suitable for extended diagnosis and batch testing.

Gold-Plated Fine Tips

Fine gold-plated contact probes improve contact reliability and measurement accuracy when testing small SMD components on high-density circuit boards.

Type-C Software Upgrade

Supports online software upgrades through a Type-C connection to a computer, helping keep the device updated with feature and performance improvements.

How To Use

How To Use

DM103 uses a compact three-button layout with Type-C charging / upgrade interface, OLED display, charging indicator, and precision tweezer tips.

Power / Mode

Press to power on. Long press to power off. In measurement mode, switch among AUTO, L, C, R, diode, and continuity.

Frequency / Menu

Use this key to switch frequency in measurement mode. Long press to enter or exit settings, then move downward.

Hold / Level

Hold the current reading in measurement mode. Long press to switch key sound, and move upward inside settings.

Type-C / OLED / Tips

Charge or upgrade through Type-C, read results on the OLED screen, and touch SMD parts with the gold-plated tips.

Before You Order And Use

Before You Order And Use

DM103 is designed for passive component and circuit-board component testing. It is not designed for live-circuit measurement.

Safety And Measurement Notes

  • Do not apply voltage during measurement.
  • DM103 is not designed for measuring live circuits.
  • Always disconnect power before testing circuit-board components.
  • Fully discharge all capacitors before measurement.
  • Always discharge capacitors before measurement to prevent device damage and improve reading accuracy.
  • Avoid high temperatures, dust, and direct sunlight during use or storage.
  • Do not use in humid environments.
  • Do not use near flammable gases or vapors to prevent safety hazards.

  2. Nicole-zhang –

    Troubleshooting tiny electronics and getting precise meter readings is often tedious. The AUTOOL DM103 Digital LCR Tweezer Smart Meter solves this hassle. Unlike standard multimeters that force you to juggle loose probes and watch the screen at the same time, this tool is simple to use: power it up, then touch its tweezer probes to your component’s wires to take measurements instantly.
