2. Safety Information

WARNING: To avoid electrical shock, do not operate the device until you have opened the battery cover and read the entire manual for safety instructions.

• Always ensure the meter is in good working condition before use.
• Do not apply voltage or current that exceeds the maximum rated values specified in the specifications.
• Use caution when working with voltages above 60V DC or 30V AC RMS, as these pose a shock hazard.
• Ensure test leads are properly connected and in good condition.
• Do not use the meter if it appears damaged or if the insulation on the test leads is compromised.
• Remove test leads from the circuit before changing functions.
• Always turn off the power to the circuit under test before making resistance or capacitance measurements.
• Discharge capacitors before measuring capacitance.

5. Setup

5.1 Battery Installation

1. Ensure the meter is powered off.
2. Locate the battery compartment on the back of the meter.
3. Open the battery cover.
4. Insert 2 AAA7 batteries, observing the correct polarity (+/-).
5. Close the battery cover securely.

5.2 Connecting Test Leads

1. Insert the red test lead into the 'VΩHz' input jack.
2. Insert the black test lead into the 'COM' input jack.
3. Ensure connections are firm before use.

6. Operating Instructions

6.1 Power On/Off

• Press the power button () to turn the meter on.
• Press and hold the power button to turn the meter off.
• The meter will automatically shut down after 15 minutes of inactivity.

6.2 Function Selection (AUTO / SELECT)

• The meter features an AUTO identification gear, which automatically selects the appropriate measurement function (voltage, resistance, continuity) when test leads are connected.
• For specific functions or to switch between AC/DC modes, press the 'SELECT' button.
• The 'H/★' button is used for Data Retention (Hold) and Backlight control.

6.3 Measuring AC/DC Voltage

1. Turn on the meter. It will typically default to AUTO mode.
2. Connect the red test lead to the positive side of the circuit and the black test lead to the negative side (or ground).
3. Read the voltage value on the display. The meter will automatically detect AC or DC voltage.
4. The voice broadcast feature will announce the stable reading.

6.4 Measuring AC Current (Clamp)

1. Turn on the meter.
2. Ensure the meter is in AC current mode (if not, use 'SELECT' button).
3. Open the clamp jaw and enclose only one single conductor (wire) of the circuit.
4. Read the AC current value on the display.
5. The voice broadcast feature will announce the stable reading.

6.5 Measuring Resistance

1. Turn off power to the circuit under test.
2. Ensure the meter is in resistance mode (Ω).
3. Connect the test leads across the component or circuit to be measured.
4. Read the resistance value on the display.
5. The voice broadcast feature will announce the stable reading.

6.6 Measuring Capacitance

1. Turn off power to the circuit under test.
2. Discharge the capacitor completely before measurement to avoid damage to the meter or injury.
3. Ensure the meter is in capacitance mode (nF/mF).
4. Connect the test leads across the capacitor terminals.
5. Read the capacitance value on the display.
6. The voice broadcast feature will announce the stable reading.

6.7 Measuring Frequency (Hz)

1. Ensure the meter is in frequency mode (Hz).
2. Connect the test leads across the circuit where frequency needs to be measured.
3. Read the frequency value on the display.
4. The voice broadcast feature will announce the stable reading.

6.8 NCV (Non-Contact Voltage) Detection

1. Select NCV mode.
2. Bring the top of the clamp meter near the conductor or outlet.
3. The meter will indicate the presence of AC voltage through visual and/or audible alerts.

6.9 Diode Test and Continuity (On/Off Beep)

1. Select Diode/Continuity mode.
2. For Diode Test: Connect the red lead to the anode and the black lead to the cathode. The display will show the forward voltage drop. Reverse the leads to check for open circuit.
3. For Continuity: Connect the test leads across the circuit or component. A beep indicates continuity (low resistance).

7. Maintenance

7.1 Cleaning

• Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents.
• Keep the meter dry.

7.2 Battery Replacement

• When the low power indication appears on the display, replace the batteries promptly.
• Follow the battery installation steps in Section 5.1.

7.3 Storage

• If the meter is not used for a long period, remove the batteries to prevent leakage.
• Store the meter in its storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.

8. Troubleshooting

• Meter does not power on: Check battery installation and ensure batteries are not depleted.
• Inaccurate readings: Ensure test leads are properly connected and not damaged. Verify the correct function is selected for the measurement.
• No reading for AC current: Ensure only a single conductor is enclosed within the clamp jaw.
• No voice broadcast: Check if the voice broadcast feature is enabled (if applicable) or if the volume is too low.

9. User Tips

• Always double-check your connections and selected function before taking a measurement to prevent damage to the meter or the circuit.
• Utilize the voice broadcast feature in low-light conditions or when your attention needs to be on the circuit rather than the display.
• The AUTO identification feature is convenient for general checks, but for precise measurements, manually select the specific function.
• Remember to discharge capacitors before measuring capacitance to avoid potential hazards and ensure accurate readings.
