5. Setup and Initial Use

5.1. Charging the Battery

The HT129 is equipped with a built-in 3.7V rechargeable Li-ion battery. Before first use, or when the low battery indicator appears, charge the device using the provided USB charging cable.

1. Connect the small end of the USB charging cable to the charging port on the multimeter.
2. Connect the other end of the USB cable to a standard USB power adapter (not included) or a computer USB port.
3. The display will show a charging indicator. Allow the device to charge fully.

5.2. Attaching Test Leads

Always ensure test leads are correctly inserted into the appropriate input terminals for the desired measurement.

1. Insert the black test lead into the "COM" (Common) terminal.
2. For most measurements (voltage, resistance, capacitance, frequency, diode, continuity, temperature), insert the red test lead into the "INPUT" terminal.
3. For current measurements:
   • For milliampere (mA) measurements, insert the red test lead into the mA terminal.
   • For ampere (A) measurements, insert the red test lead into the 10A terminal.

Caution: Incorrect connection of test leads can damage the multimeter or the circuit under test.

6. Operating Modes and Measurements

The HT129 features both Manual and Smart (Auto Range) measurement modes. In Smart mode, the multimeter automatically detects the measurement type (AC/DC voltage, resistance, continuity). For advanced applications, switch to Manual mode using the "FUNC" button.

6.1. AC/DC Voltage Measurement (V)

1. Turn on the multimeter.
2. Connect the black test lead to the COM terminal and the red test lead to the INPUT terminal.
3. Select the appropriate voltage range (or use Smart mode).
4. Connect the test probes in parallel across the component or circuit to measure voltage.

6.2. AC/DC Current Measurement (A/mA)

1. Turn off power to the circuit.
2. Connect the black test lead to the COM terminal.
3. For mA measurements, connect the red test lead to the mA terminal. For A measurements, connect the red test lead to the 10A terminal.
4. Break the circuit and connect the multimeter in series with the component to measure current.
5. Restore power to the circuit.

Caution: Never connect the multimeter in parallel for current measurement, as this will cause a short circuit and damage the device.

6.3. Resistance Measurement (Ω)

1. Ensure the circuit is de-energized.
2. Connect test leads to COM and INPUT terminals.
3. Select the resistance measurement mode.
4. Connect the test probes across the component to measure its resistance.

6.4. Capacitance Measurement (F)

1. Ensure the capacitor is fully discharged before measurement.
2. Connect test leads to COM and INPUT terminals.
3. Select the capacitance measurement mode.
4. Connect the test probes across the capacitor.

6.5. Frequency/Duty Cycle Measurement (Hz/%)

1. Connect test leads to COM and INPUT terminals.
2. Select the frequency/duty cycle mode.
3. Connect the test probes to the signal source.

6.6. Diode Test (→|)

1. Ensure the circuit is de-energized.
2. Connect test leads to COM and INPUT terminals.
3. Select the diode test mode.
4. Connect the red probe to the anode and the black probe to the cathode of the diode. The forward voltage drop will be displayed. Reverse the probes to check for open circuit.

6.7. Continuity Test (Ω))

1. Ensure the circuit is de-energized.
2. Connect test leads to COM and INPUT terminals.
3. Select the continuity test mode.
4. Connect the test probes across the circuit or component. A continuous beep indicates continuity (low resistance).

6.8. NCV (Non-Contact Voltage) Detection

The NCV function allows for detection of AC voltage without direct contact with conductors.

1. Select the NCV mode.
2. Approach the NCV sensing area (top of the multimeter) near the conductor being tested.
3. A weak AC signal ("---L") will result in a slow beep and green indicator light.
4. A strong AC signal ("---H") will result in a rapid beep and red indicator light.

6.9. Live and Neutral Wire Detection

This function helps identify live and neutral wires using a single test probe.

1. Select the Live Test mode.
2. Contact the red test probe to the conductor being tested.
3. If "---L" is displayed with a slow beep and green indicator, it's a weak AC signal (likely neutral).
4. If "---H" is displayed with a rapid beep and red indicator, it's a strong AC signal (likely live).

6.10. Temperature Measurement

The HT129 can measure temperature using the provided K-type thermocouple.

1. Connect the thermocouple to the COM and INPUT terminals (observe polarity if applicable).
2. Select the temperature measurement mode (usually °C/°F).
3. Place the thermocouple tip at the point where temperature needs to be measured.

7. Special Features

7.1. True RMS

The HT129 features True RMS measurement, which provides accurate readings for non-sinusoidal AC waveforms, unlike average-responding meters.

7.2. Data Hold (HOLD)

Press the "HOLD/REL" button briefly to freeze the current reading on the display. Press again to release.

7.3. Max/Min Data Hold (MAX/MIN)

Press the "MAX/MIN" button to enter Max/Min recording mode. The meter will display the maximum or minimum value measured since entering this mode. Press again to cycle between MAX, MIN, and current reading. Hold to exit.

7.4. Auto Power Off

To conserve battery life, the multimeter will automatically shut down after approximately 15 minutes of inactivity (no button operation). This function is enabled by default. To disable/enable, refer to the full user manual.

7.5. Backlight and Flashlight

The VA color display has a backlight for visibility in low-light conditions. The integrated flashlight can be activated to illuminate your work area.

8. Specifications

9. Maintenance

9.1. Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is dry before use.

9.2. Battery Care

The HT129 uses a built-in rechargeable Li-ion battery. If the meter is not used for an extended period, charge it periodically to maintain battery health. Do not attempt to replace the internal battery yourself; contact qualified service personnel.

9.3. Fuse Replacement

If the current measurement function stops working, the fuse may need replacement. Fuse specifications are F630mA/250V for mA range and F10A/250V for 10A range. Fuse replacement should only be performed by qualified personnel to ensure safety and proper function.

10. Troubleshooting

• No display or dim display: Check battery charge level. Recharge the battery if low.
• Incorrect readings: Ensure test leads are correctly inserted and making good contact. Verify the correct measurement mode is selected. Check for damaged test leads.
• "OL" or "OVER" on display: Indicates an overload or out-of-range measurement. Select a higher range or ensure the input is within the meter's capabilities.
• Current measurement not working: Check the fuse. If blown, it needs replacement by a qualified technician.
• NCV/Live detection inconsistent: Ensure there are no strong interfering electromagnetic fields nearby.

11. User Tips

• Utilize the back bracket for hands-free operation, especially when taking multiple measurements.
• The flashlight is useful for working in poorly lit electrical panels or dark corners.
• Always double-check the selected function and lead connections before making any measurement to prevent damage to the meter or circuit.
• For precise temperature readings, ensure the thermocouple is in direct contact with the surface or medium being measured.
