2. Safety Information
Always observe the following safety precautions to prevent electric shock, injury, or damage to the multimeter and the equipment under test.
- Do not exceed the maximum input limits specified for each measurement range.
- Ensure test leads are properly connected to the correct input jacks before making any measurements.
- Do not use the multimeter if it appears damaged or if the test leads are compromised.
- Always disconnect power to the circuit or component before testing resistance, continuity, or capacitance.
- Exercise extreme caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
- Keep fingers behind the finger guards on the test probes during use.
- Replace batteries immediately when the low battery indicator appears to ensure accurate readings.

4. Setup
Follow these steps to prepare your multimeter for first use.
- Unpack: Carefully remove the multimeter and all accessories from the packaging. Inspect for any signs of damage.
- Battery Installation: Open the battery compartment cover on the back of the multimeter. Insert the required batteries (typically AAA, refer to specifications) ensuring correct polarity. Close the cover securely.
- Connect Test Leads: Insert the red test lead into the "INPUT" jack and the black test lead into the "COM" (common) jack. Ensure they are firmly seated.
5. Operating Instructions
This section details the basic operation of your TA804A multimeter.
5.1 Power On/Off
To power on the multimeter, press and hold the power button (usually marked with "⑉"). To power off, press and hold the power button again. The device features an automatic power-off function to conserve battery life after a period of inactivity.
5.2 Automatic Measurement Mode
The TA804A is equipped with an intelligent automatic recognition function. When powered on, it typically defaults to AUTO mode. In this mode, the multimeter will automatically detect the type of measurement (AC/DC voltage, resistance, continuity) and display the appropriate reading without manual range selection.

5.3 Specific Measurement Functions
- Voltage Measurement (AC/DC): Connect the test leads in parallel to the circuit or component. The multimeter will automatically detect and display the voltage.
- Resistance Measurement: Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
- Continuity Test: Ensure the circuit is de-energized. Connect the test leads across the component. A low resistance (typically below 50 ohms) will indicate continuity, often accompanied by an audible beep.
- Frequency Measurement (Hz): The multimeter can display the frequency of an AC signal.
- Non-Contact Voltage (NCV) Detection: Activate the NCV function (if available via a dedicated button). Hold the top of the multimeter near a live wire. The device will indicate the presence of AC voltage through visual and/or audible alerts.
5.4 Data Hold Function
Press the "HOLD" button to freeze the current reading on the display. This is useful for recording measurements in hard-to-reach areas. Press the button again to release the hold and resume live readings.
6. Maintenance
Proper care and maintenance will ensure the longevity and accuracy of your multimeter.
- Cleaning: Keep the device clean and dry. Use a soft, damp cloth to wipe the casing. Do not use abrasive cleaners or solvents.
- Battery Replacement: When the low battery indicator appears on the display, replace the batteries promptly to maintain measurement accuracy. Always use the specified battery type.
- Storage: Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Inspection: Periodically inspect the test leads for any signs of damage, such as cracks or frayed insulation. Replace damaged leads immediately.
7. Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Dead or low batteries; Incorrect battery installation | Replace batteries; Check battery polarity |
| Incorrect or unstable reading | Poor test lead connection; Exceeding input limits; External interference | Ensure leads are firmly connected; Do not exceed limits; Move away from strong electromagnetic fields |
| Multimeter does not turn on | Batteries are completely drained; Device malfunction | Replace batteries; If issue persists, contact customer support |
