Note: To measure the current you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying the current and ground wires. The current in two wires always flows in opposite directions, so the magnetic fields from two wires cancel each other, therefore the meter reads 0 A
The NCV function can test the voltage without contact. When the Meter senses a weak AC signal, the green indicator light will be on and the buzzer will emit a slow, audible beep. When the Meter senses a strong AC signal, the red indicator light will be on and the buzzer will emit a brief beep.
AstroAI 4000 Counts TRMS Clamp Meter
Detects Live Wires
Live wire testing with the red test lead. This unique function tests the presence of live wires. When it detects a live wire, the multimeter will reflect with the audio alarm.
Frequency and Duty Cycle Test
Turn the rotary dial to the “Hz/%” setting (Duty Cycle Test: Please press the FUNC button to duty cycle test.) The screen will display “ HZ/% ” indicating the measurement function.
Test AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc.
The CM4KOR Clamp Meter can accurately measure AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc.
Zero Function
This function helps decrease the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement.
Backlit LCD and Flashlight
The Backlit LCD and Flashlight ensure clear measurements in a dimly lit area. The Backlight can be switched manually and shuts off automatically after 15 minutes.
Continuity Test
Connect test leads to the circuit, the buzzer inside the Meter will beep if the resistance<50Ω.
Correct Measurement
Please measure in the correct way, otherwise the readings will not be accurate.
NCV Detection
This multimeter features non-contact voltage testing with a sound and light alarm. When the indicator light is on, it means there is voltage, please pay attention to your safety.
