4. Setup
4.1. Battery Installation
The meter requires batteries for operation. To install or replace batteries:
- Ensure the meter is powered off.
- Locate the battery compartment on the back of the meter.
- Use a screwdriver to open the battery compartment cover.
- Insert new batteries, observing correct polarity.
- Securely close the battery compartment cover.
4.2. Initial Power On
Press the power button to turn on the meter. The default intelligent mode will activate, automatically identifying common measurement signals.
5. Operating Instructions
5.1. Smart Mode
When the meter is powered on, it defaults to Smart Mode. In this mode, the meter automatically detects and measures AC/DC voltage, AC/DC current, resistance, and continuity, simplifying operation.
5.2. Function Selection
Rotate the rotary dial to select specific measurement functions as needed. Press the SEL/FUNC button to cycle through sub-functions within a selected range (e.g., AC/DC voltage).
5.3. AC/DC Voltage Measurement
To measure voltage:
- Insert the red test lead into the "VΩHz" input jack and the black test lead into the "COM" input jack.
- Select the voltage measurement function using the rotary dial.
- Connect the test leads in parallel to the circuit or component under test.
- Read the voltage value on the display.

5.4. AC/DC Current Measurement
To measure current:
- Select the current measurement function (A~) or (A=) using the rotary dial.
- Open the clamp jaws and enclose only one conductor of the circuit. Ensure the jaws are fully closed.
- Read the current value on the display.
5.5. Resistance and Continuity Measurement
To measure resistance or check continuity:
- Insert the red test lead into the "VΩHz" input jack and the black test lead into the "COM" input jack.
- Select the resistance/continuity function using the rotary dial.
- Connect the test leads across the component. For continuity, a beep indicates a continuous circuit.
5.6. Non-Contact Voltage (NCV) Detection
The NCV function allows detection of AC voltage without direct contact.
- Press the NCV button on the right side of the meter.
- Move the meter's NCV sensor close to the conductor.
- The meter will indicate the presence of AC voltage through audible beeps and visual indicators (Low Voltage 'L' or High Voltage 'H').

5.7. Low Pass Filter (LPF)
The LPF function is used for accurate voltage measurements on variable frequency drives (VFDs) or other noisy circuits. It filters out high-frequency interference.
- Select the AC voltage function.
- Press the LPF button to activate the Low Pass Filter.
- Proceed with AC voltage measurement as usual.

5.8. Inrush Current Measurement
The Inrush function measures the initial surge current when a device is powered on.
- Select the Inrush current function using the rotary dial.
- Open the clamp jaws and enclose one conductor of the device to be tested.
- Power on the device. The meter will capture and display the peak inrush current.

5.9. Data Hold (HOLD)
Press the HOLD button (short press the NCV button) to freeze the current reading on the display. Press it again to release the hold function.
5.10. MAX/MIN Measurement
Press the MAX/MIN button to record the maximum and minimum values during a measurement session. Press again to cycle between MAX, MIN, and current readings.
5.11. Flashlight
Press the flashlight button to illuminate the measurement area. Press again to turn it off.
5.12. Auto-Off Function
The meter will automatically power off after approximately 15 minutes of inactivity to conserve battery life. Press any button or rotate the dial to reactivate it.
6. Maintenance
6.1. Cleaning
Wipe the meter's casing with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is dry before storage or use.
6.2. Battery Replacement
Replace batteries when the low battery indicator appears on the display. Refer to Section 4.1 for battery installation instructions.
6.3. Storage
If the meter is not used for an extended period, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter does not power on. | Dead or incorrectly installed batteries. | Replace batteries, ensuring correct polarity. |
| Inaccurate readings. | Incorrect function selected, damaged test leads, or external interference. | Verify function selection, inspect/replace test leads, move away from strong electromagnetic fields. |
| No continuity beep. | Open circuit or high resistance. | Check the circuit for breaks or high resistance points. |
| NCV not detecting voltage. | No AC voltage present, or sensor not close enough to the conductor. | Ensure AC voltage is present. Move the NCV sensor closer to the live conductor. |
