- Locate the battery cover on the rear of the device.
- Open the battery cover by sliding or unscrewing it.
- Insert the required AAA batteries, observing the polarity markings (+ and -).
- Close the battery cover securely.
Initial Checks
- Before first use, inspect the devices and test leads for any signs of damage. Do not use if damaged.
- Turn on the device to ensure the display illuminates and functions correctly.
Operating Instructions
ST181 Clamp Meter
The ST181 Clamp Meter is a versatile tool for various electrical measurements. Always ensure the correct function is selected before making any measurements.
- AC Current Measurement:
Rotate the dial to the "A~" position. Open the clamp jaws and encircle a single conductor (not a bundle of wires). The current reading will appear on the display.
Figure 2: ST181 Clamp Meter displaying AC current measurement and indicating various functions like AC/DC voltage, diode, resistance, capacitance, NCV, backlight, and frequency.
- AC/DC Voltage Measurement:
Connect the test leads to the "VΩHz" and "COM" input jacks. Rotate the dial to the "V~" (AC Voltage) or "V-" (DC Voltage) position. Touch the test probes to the circuit points to be measured.
- Resistance Measurement:
Connect the test leads to the "VΩHz" and "COM" input jacks. Rotate the dial to the "Ω" position. Touch the test probes across the component to measure resistance.
- Capacitance Measurement:
Connect the test leads to the "VΩHz" and "COM" input jacks. Rotate the dial to the "nF" position. Touch the test probes to the capacitor terminals. Ensure the capacitor is discharged before testing.
- Diode Test:
Connect the test leads to the "VΩHz" and "COM" input jacks. Rotate the dial to the diode symbol position. Connect the red probe to the anode and the black probe to the cathode of the diode. The forward voltage drop will be displayed.
- Continuity Test:
Connect the test leads to the "VΩHz" and "COM" input jacks. Rotate the dial to the continuity symbol position. Touch the test probes to the two points of the circuit. A continuous beep indicates continuity.
- Frequency Measurement (Hz):
Connect the test leads to the "VΩHz" and "COM" input jacks. Rotate the dial to the "Hz" position. Touch the test probes to the circuit where frequency needs to be measured.
- Backlight Operation:
Press the "H/BL" button to activate or deactivate the HD backlight for improved visibility in low-light conditions.

- Jaw Opening and Usage:
The clamp meter features a 36mm (1.42 inches) jaw opening. Press the lever to open the jaws and place them around a single conductor for non-contact current measurement.

VD807 Non-Contact Voltage Tester
The VD807 is designed for quick and safe detection of AC voltage without direct contact.
- NCV (Non-Contact Voltage) Function:
Turn on the VD807. Place the tip of the tester near an AC voltage source (e.g., a power outlet, insulated wire). The device will beep and illuminate LEDs to indicate the presence and strength of the AC signal.
Figure 5: VD807 Voltage Tester demonstrating non-contact voltage (NCV) induction near an electrical outlet.
- AC Voltage Detection:
Similar to NCV, the VD807 can detect AC voltage by placing its tip near the source. The display will show the voltage level and the indicator lights will respond.
Figure 6: VD807 Voltage Tester detecting AC voltage by placing its tip near a live point.
- Live/Zero Wire Identification:
When detecting voltage, the VD807's display will change color to indicate the type of wire. A red screen typically indicates a live wire, while a green screen indicates a neutral (zero) wire.
Figure 7: VD807 Voltage Tester's two-color display, showing red for live wire and green for neutral wire.
- Line Breakpoint Detection:
To find a breakpoint in a wire, move the VD807 along the insulated wire. The indicator will change or stop indicating voltage at the point of the break.

Maintenance
- Cleaning: Wipe the devices with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate readings. Refer to the "Battery Installation" section for instructions.
- Storage: Store the devices in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Inspection: Regularly inspect the test leads and device casings for any signs of wear or damage. Replace damaged components immediately.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Dead or incorrectly installed batteries. | Replace batteries, ensuring correct polarity. |
| Inaccurate readings. | Low battery; incorrect function selected; poor test lead connection; external interference. | Replace batteries; select correct function; ensure secure connections; move away from strong electromagnetic fields. |
| NCV function not detecting voltage. | Voltage too low; device not close enough to source; thick insulation. | Ensure voltage is within detection range (AC 12-300V); bring tester closer to the source; consider direct contact measurement if safe. |
| No continuity beep. | Open circuit; faulty test leads. | Check the circuit for breaks; test leads for damage. |
