Video 1: Product demonstration showing various measurement functions of the ANENG ST180 Clamp Meter and B19 Tester Pen.

6.1.1. AC Current Measurement

Turn the function dial to the 'A~' (AC Current) position.
Open the clamp jaw using the trigger.
Clamp around a single live wire (not a bundle of wires) of the circuit you wish to measure.
Read the AC current value on the display.

AC Current Measurement Clamp Position Guide — Figure 8: Guide for correct clamping position during AC current measurement. The measured fluid should be placed in the center of the clamp to avoid length error.

AC Current Measurement Warning: Single Core Line Only — Figure 9: Important note: AC current measurement can only measure the zero line or fire line, and only a single core line. It cannot measure the common electrical appliances in the home power supply line if it contains multiple core wires.

Pre-measurement Current Estimation and Range Selection — Figure 10: Before measurement, estimate the current and select the appropriate range. If the current is unknown, select the maximum range and reduce it appropriately. The range cannot be converted during measurement.

6.1.2. AC Voltage Measurement

Turn the function dial to the 'V~' (AC Voltage) position.
Insert test leads into the VΩHz and COM jacks.
Touch the test probes to the points where you want to measure AC voltage.
Read the AC voltage value on the display.

ST180 Clamp Meter AC/DC Voltage and AC Current Measurement Examples — Figure 11: Examples of AC Current, DC Voltage, and AC Voltage measurements using the ST180 Clamp Meter.

6.1.3. DC Voltage Measurement

Turn the function dial to the 'V=' (DC Voltage) position.
Insert test leads into the VΩHz and COM jacks.
Touch the test probes to the points where you want to measure DC voltage.

Turn the function dial to the 'NCV' position.
Move the top of the clamp meter near a live wire or electrical outlet.
The device will emit a beep and the LED will flash red if AC voltage is detected. The closer the device is to the voltage source, the faster the alarm sounds.

ST180 Clamp Meter NCV Induction Detection — Figure 17: Illustration of NCV induction detection with the ST180 Clamp Meter. The screen will display '----' and emit a buzzer sound, and the LED will flash red.

6.1.10. Live Detection (Zero Fire Detection)

Turn the function dial to the 'Live' position.
Insert the red test lead into the VΩHz jack and the black test lead into the COM jack.
Touch the red test probe to the suspected live wire and the black test probe to the neutral wire or ground.
The screen will display "EF" and emit a beep, and the LED will flash red for a live wire. If the screen displays "EF" with no beep, it is the zero line.

ST180 Clamp Meter Live Detection (Neutral vs. Firewire) — Figure 18: Live Detection using the ST180 Clamp Meter. When the screen displays "----" and emits a beep with a red LED flash, it's a firewire. If the screen displays "EF" with no beep, it's the zero line.

6.1.11. Flashlight

Long press the 'SEL' button to activate the flashlight for illumination in dark environments.

7. Maintenance

Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate readings. Refer to Section 5.1 for battery installation.
Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
Test Leads: Regularly inspect test leads for any signs of damage, such as cracks or frayed insulation. Replace damaged leads immediately.

8. Troubleshooting

No Display/Faint Display: Check battery levels and replace if necessary. Ensure batteries are inserted with correct polarity.
Inaccurate Readings: Verify that the correct function and range are selected for the measurement. Ensure test leads are properly connected and undamaged. Clean the test probes if they are dirty.
No NCV Detection: Ensure the NCV function is selected. The device needs to be close enough to the AC voltage source.
Device Not Turning On: Check battery installation and charge.
Auto Shutdown: Both devices feature an auto-shutdown function (ST180 after 15 minutes, B19 after 3 minutes) to conserve battery life. This is normal operation.

9. User Tips

Always double-check your function and range selection before making any measurement to prevent damage to the meter or inaccurate readings.
When measuring AC current with the clamp meter, always isolate a single conductor (live or neutral) to get an accurate reading. Clamping around a cable containing both live and neutral wires will result in a zero reading due to opposing magnetic fields.
Utilize the backlight feature in dimly lit areas for better visibility of the display.
The B19 Tester Pen is excellent for quick checks and identifying live wires without direct contact, enhancing safety.
Keep the devices clean and free from dust and moisture to prolong their lifespan and maintain accuracy.
