User Manual

1. Introduction

This product is a battery-powered, true-rms, auto ranging digital clamp multimeter with a 6000 counts LCD display and a backlight.

2. Safety Information

To avoid possible electrical shock, fire, or personal injury, please read all safety information before you use the product.

1. Do NOT exceed the "maximum value" indicated in the Specification.
2. Examine the connection of the test leads and the insulation of the product before measuring voltage higher than 36V DC or 25V AC.
3. Disconnect the test leads from the circuit before changing the mode.
4. Misuse of mode or range can lead to hazards, be cautious. "OL" will be shown on the display when the input is out of range.

4. Instruction

(1) Front Panel

The front panel of the digital clamp meter is illustrated with the following numbered components:

1. Jaw: The clamp mechanism for measuring current.
2. Jaw release: A lever to open the clamp jaws.
3. "NCV "Indicator light: A light that illuminates when Non-Contact Voltage is detected.
4. ? /H (Numeric hold/screen backlit): A button for holding the displayed value or toggling the screen backlight. A short press holds or cancels the value; a long press (approx. 2 seconds) turns the backlight on or off. This key is also used to clear data in capacitive mode.
5. ⚙️ SELECT: A button used to cycle through measurement modes (e.g., Hz, NCV, TEMP) in automatic identification mode. A long press (approx. 2 seconds) returns to automatic identification mode.
6. ▶️ (Power): The power button. A short press starts the machine and enters the default automatic identification mode (voltage, resistance, current). A long press (approx. 2 seconds) turns the machine off.
7. LCD display: The screen where measurements are shown.
8. COM: The common (negative) input jack for test leads.
9. INPUT: The positive input jack for test leads.

(2) Measure AC/DC Voltage

1. The minimum voltage of this product is 1V. When the measured voltage is higher than 1V, the product will display the reading.
2. Connect the black test lead to the COM Terminal and connect the red test lead to the INPUT Terminal.
3. The DC or AC voltage will be matched automatically.
4. Touch the probes to the correct test points of the circuit to measure the voltage.
5. Read the measured voltage on the display.

* Caution:
a. Do not measure voltage that exceeds the MAX Value as indicated in the Specifications.
b. Do not touch high voltage circuit during measurements.

(3) AC Current

1. Power on; the current can be automatically identified in the default automatic identification mode.
2. Pull the trigger of the tongs, pass the single wire through the center of the tongs, and tighten the tongs.
3. The monitor displays the measured current value.

* Caution:
a. Do not measure current that exceeds the MAX Value as indicated in the Specifications.
b. Measure one wire at a time because current moving in different directions will cancel each other out.

(4) Measure Resistance and Continuity

1. Connect the black test lead to the COM Terminal and connect the red test lead to the INPUT Terminal.
2. Resistance can be identified automatically.
3. Touch the probes to the desired test points of the circuit to measure the resistance.
4. The monitor displays the measured resistance value.
5. When the measured resistance value is less than 50 Ω, the Continuity mode is automatically entered, and the buzzer sounds an alarm.

* Caution:
a. Disconnect circuit power and discharge all capacitors before you test resistance.
b. Do not input voltage in the Resistance Mode.

(5) Measure Diode

1. Connect the black test lead to the "COM" Terminal and the red lead to the INPUT Terminal.
2. Press the ▶️ button to start the machine, then press the “SELECT” button once to enter the DIODE measurement mode.
3. Connect the red probe to the anode side and the black probe to the cathode side of the diode to be tested.
4. The display shows the measured values.

(6) Measure Capacitance

1. Discharge all capacitors before you test capacitance.
2. Connect the black test lead to the "COM" Terminal and the red lead to the INPUT Terminal.
3. Press the ▶️ button to start the machine, then press the “SELECT” button twice to enter the capacitance measurement mode.
4. Connect the red probe to the anode side and the black probe to the cathode side of the capacitor to be tested.
5. The monitor reads the measured capacitance value.

(7) Frequency measurement

1. Press "▶️" to start the machine, Press "SELECT" three times to enter "Hz" mode.
2. Connect the black test lead to the "COM" Terminal and the red lead to the INPUT Terminal.
3. Use a test pen to measure the frequency of the line voltage.
4. The display screen reads the measured frequency.

(8) Measure NCV

1. Press "▶️" to start the machine, Then press "Select" four times to enter "NCV" mode.
2. Move it around; the built-in beeper will beep when the inner sensor detects AC voltage nearby. The stronger the voltage, the quicker the beeper beeps.

(9) Temperature measurement

1. Press "▶️" to start the machine, Press the "Select" button 5 times to enter the "°C" mode, or Press "Select" six times to enter "°F" mode.
2. The temperature inside the meter is displayed on the screen. If you want to measure the ambient temperature, it needs to be placed for a period of time.
3. If you want to measure the temperature of other objects or liquids, you need to use the corresponding temperature probe. Insert the temperature probe into the "COM" and "INPUT" sockets, and use the detection end of the sensor to contact the temperature of the measuring object.

(10) Auto Power off

1. The product automatically powers off after 15 minutes of inactivity.
2. The built-in beeper beeps 5 times 1 minute before power off.
3. To disable the Auto Power Off function, hold down the "SELECT” button when turning on the product; you will hear five beeps if you have successfully disabled the function.

E. General Maintenance

Beyond replacing batteries and fuses, do not attempt to repair or service the product unless you are qualified to do so and have the relevant calibration, performance test, and service instructions.
