Safety Statement

Read carefully all the following safety precautions to avoid personal injuries and prevent damage to the device or any products connected to it. Failure to follow these safety instructions could result in personal injuries or risk of fire.

  1. Please use only the power cable dedicated for this product or certified by your country/region.
  2. Before connecting and disconnecting DT71’s tips to device under test, please power off the circuit to be tested, and after connecting DT71’s tips correctly, power on and measure the circuit.
  3. It is recommended to unplug the controller when DT71 is not in use.
  4. To avoid fire or electric shock, please observe all terminal ratings and marking instructions to avoid damage to the device. Before connecting DT71, please consult the product manual or product label for information about the rated values;

Product Introduction

DT71 Mini Digital Tweezers is a multi-function measure tool with a fully differential input and built-in signal generator. DT71 has a unique ternary structure, which can be split into a controller, test arms  and tweezer tips, flexible in replacement and combination. DT71 uses thickened gold-plated tweezer tips, which can be replaced according to the application scenario. It can measure various devices such as resistor, capacitor, inductor, voltage, frequency, diode, etc. to help users quickly identify components. The built-in micro signal generator of DT71 can output a variety of signals, providing a perfect solution for the debugging and maintenance of complex electronic systems and the classification and detection of discrete chip components.


FIG 1 Appearance



DT71 Mini Digital Tweezers is a new concept portable LCR tester, which can automatically identify the type of electronic components and actively select the appropriate range for measure; the built-in signal generator can output a variety of required signals for electronic system debugging and maintenance.

How to charge

Insert the 3.Smm male plug of the dedicated data cable into DT71’s test arms, and then connect a DCSV power supply to charge the test arms. The charging indicator light is always on when charging, and off when fully charged.

FIG 9 How to charge

Automatic sleep and wake up

DT71 has automatic sleep function, when DT71 remains static for 60 seconds (factory setting), it will automatically enter sleep mode; When you need to use it again, close (short-circuit) the tweezer tips to wake up DT71 to enter user interface.



Preparation before measuring

Before measuring, please connect DT71 controller to test arms, or short-circuit the tweezer tips to wake up DT71. When the screen displays, select the correct measure mode to start measuring.

Measure parameters and accuracy:

FIG 10 Measure parameters and accuracy

The test data comes from laboratory environment and is for reference only.
True error range = ±(reading*accuracy + corresponding resolution*value)

Note: Maximum absolute input voltage: -5V – SOV; Input resistance: 1 Mn.

FIG 15 Zero Calibration

Zero Calibration

  1. Long press DT71’s touch button to switch to calibration mode (Calibration);
  2. Keep the tweezer tips closed and short circuit until the screen prompts the next step;
  3. Open the tweezer tips and keep it open until the screen prompts the next step;
  4. After the open calibration is successful, the screen will prompt whether to save the calibration data, tap the touch button to confirm and save.
    * If you mistakenly enter calibration mode, long press the touch button to exit.

Accurate Calibration
For accurate calibration, please visit and download the DT71 calibration accessories, and operate according to the instructions.
