4. Setup
4.1. Initial Charging
Before first use, fully charge the device. Connect the provided USB Type-C cable to the charging port on the ZT-MD1 and the other end to a 5V/A USB power adapter (not included). The battery indicator on the screen will show charging status. A full charge ensures optimal performance and battery life.
4.2. Attaching Tweezer Tips
The ZT-MD1 comes with detachable gold-plated tweezer tips. Ensure they are securely attached to the arms of the device for accurate measurements. Gently push the tips into place until they are firm. To replace, carefully pull them out.

5. Operating Instructions
5.1. Power On/Off
Press and hold the power button to turn the device on or off. The OLED screen will illuminate upon power-on.
5.2. Automatic Measurement
The ZT-MD1 defaults to automatic recognition mode. Simply touch the tweezer tips to the component you wish to measure. The device will automatically detect whether it is a resistor, capacitor, or inductor and display the corresponding value along with secondary parameters (D, Q, Rs) if applicable.
5.3. Manual Mode and Parameter Selection
Refer to the on-screen interface for options to switch between automatic and manual measurement modes, or to select specific test frequencies (100Hz, 1kHz, 10KHz) and test voltages (0.3V, 0.6V RMS) if needed for advanced measurements.
5.4. Data Hold Function
Press the "Hold" button (if available, or indicated on screen) to freeze the current measurement reading on the display. Press again to release.
5.5. Flipping the Screen Display
The screen display can be flipped for better viewing angles. Consult the device's on-screen menu or physical buttons for this function.

6. Calibration
6.1. User Calibration Learning Mode
The ZT-MD1 supports a user calibration learning mode. To perform user calibration, connect a known standard resistor to the tweezer tips and follow the on-screen instructions. This allows the device to adjust its readings for improved accuracy based on your specific reference.
6.2. Factory Reset
If necessary, factory calibration data can be restored by performing a factory reset. This will revert all settings and calibration data to their original factory values. Consult the device's menu for the factory reset option.
7. Maintenance
7.1. Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the tweezer tips are clean and free of debris for accurate contact.
7.2. Storage
When not in use, store the ZT-MD1 in its provided storage bag to protect it from dust and physical damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
7.3. Battery Care
To prolong battery life, avoid fully discharging the device frequently. Recharge the battery when the low battery indicator appears. If storing for an extended period, charge the battery to approximately 50% and recharge every few months.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is depleted. | Connect the device to a 5V/A USB charger using the provided Type-C cable and allow it to charge for at least 30 minutes before attempting to power on again. |
| Inaccurate readings. | Dirty or loose tweezer tips; device needs calibration. | Ensure tweezer tips are clean and securely attached. Perform user calibration with a known standard resistor. If issues persist, consider a factory reset. |
| Screen is blank or unresponsive. | Device frozen; low battery. | Try pressing and holding the power button for 10 seconds to force a restart. Ensure the battery is charged. |
| Cannot connect to PC for data export. | Incorrect cable or driver issues. | Ensure you are using the provided USB data cable. Check PC device manager for driver installation. Try a different USB port. |
