OPERATE INSTRUCTIONS

AC current measurement

1. Turn the dial knob to the AC current range, Press and hold the trigger to open the clamp head and use the clamp head to grab the measured conductor, then slowly release the trigger until the clamp head is completely closed, please make sure whether the measured conductor is clamped in the center of the clamp head, otherwise, it will occur additional errors. The clamp meter can only measure one current conductor at a time. If two or more current conductors are measured at the same time, the measurement readings will be wrong.
2. Read the True RMS of AC current directly from the display.

Note:
a. The current measurement function must be operated between 0℃C~40℃.
b. In order to ensure the accuracy of the measurement data, the measured conductor must be placed in the center of the clamp head. Otherwise, ±1.0% additional error of the reading will occur.
c. When the measured current is higher than 500A, the continuous test time cannot exceed 60 seconds.

AC and DC voltage measurement

1. Turn the meter knob to the AC and DC voltage range, Insert the red test lead into the ” “jack and the black test lead into the COM jack.
2. Connect the red and black test lead to the measured circuit and read the reading directly from the display.

Note:
a. Do not input voltage higher than DC/AC600V to avoid damage the meter.
b. When measuring high voltage, pay special attention to avoid electric shock.
c. Disconnect the test lead from the measuredcircuit after all measurement operations are completed.
d. When the measured voltage is higher than 24V DC/AC safe voltage, the LCD of this meter displays the high-voltage prompt ” ” for warning.
e. When measuring voltage above 36V, pay attention to wear safety protection equipment.3.

LowZ low impedance AC voltage measurement

1. Insert the red test lead into the ”  “jack and the black test lead into the COM jack.
2. Turn the meter knob to the low impedance AC voltage measurement range, and connect the test leads in parallel to the measured power supply or load.
3. Read the True RMS of AC voltage directly from the display.

Note:

• Do not input voltage higher than AC300V. Although it is possible to measure higher voltage, it may easily damage the meter.
• When measuring high voltage, pay special attention to avoid electric shock.
• Test a known voltage before use the meter, it is to confirm whether the product function is correct.
• After using LowZ low impedance function range, please wait 3 minutes before perform LowZ voltage measurement, in order to eliminate false voltages, the LowZ function of the meter will provide a low impedance on the entire wire circuit to obtain more accurate measurements.
• ►When the measured voltage is higher than
  24V AC safe voltage, the LCD of this meter
  displays the high-voltage prompt ” ” for
  warning.

Resistance measurement

1. Turn the knob to the ” “range, the meter defaults to the resistance range.
2. Insert the red test lead into the ” “jack and the black test lead into the COM jack.
3. Connect the test lead wire to both ends of the measured resistance.
4. Read the reading directly from the LCD screen.

Note:

• If the tested resistor is under open circuit or the resistance of the measured resistor exceeds the maximum range of the meter, the display will show “OL”
• When measuring on-line resistance, all power supplies in the measured circuit must be turned off before the measurement, and all capacitors are released completely. In order to ensure the measurement is correct.
• When measuring low resistance, the test leads will have about 0.1Ω-0.2Ω measurement error. In order to obtain accurate readings, you can perform relative value measurement, after the test leads are short-circuited ,subtract (clear) firstly the displayed value ,then perform the low resistance measurement.
• If the resistance value is higher than 0.5Ωwhen the test leads are short-circuited, you need to check whether the test leads are loose or other reasons.
• When measuring resistance above 1MΩ, it may take a few seconds for the reading to stabilize. It is normal for high resistance measurements. In order to obtain stable readings, you can buy an extra short alligator clip test line instead of our standard test leads to do the measurement.
• Disconnect the test lead from the measured circuit after all measurement operations are completed.

Diode and continuity test

1. Insert the red test lead into the ” “jack and the black test lead into the COM jack.
2. Turn the knob to the resistance range, short press “SELECT” to select diode or continuity test measurement mode.

4. In the diode measurement mode, connect the red test lead and black test lead to the positive and negative pole of the diode respectively, and the LCD will display the forward voltage drop of the diode.

Note:

• If the open circuit or polarity of the measured diode is reversely connect, the display will show “OL”.
• When measuring diode and continuity test, all power supplies in the measured circuit must be turned off before the measurement, and all capacitors should release completely.
• Do not input voltage higher than DC or AC 30V to avoid personal safety injury.
• Disconnect the test lead from the measured circuit after all measurement operations are completed.

Live Wire Recognition Live

1. Turn the knob to the Live range, short press the select button to switch the Live function, and the LCD displays Live.
2. Insert the red test lead into the ” ” jack, and touch the measured position with the red test lead.
3. If meter has audible and visual alarm, the tested wire connected to the red test lead is a live wire. If it is no change, the tested wire is not a live line.

Note:

• The range must be operated in accordance with safety rules.
• This function only detects AC standard main live wire (AC 110V~AC 380V).

Non-contact AC voltage induction measurement NCV

1. Turn the knob to NCV range, and the LCD displays NCV.
2. The NCV induction voltage range is 48V~250V.Put the upper part of the clamp head of the instrument close to the measured charged electric field (AC power line, socket, etc.), when the instrument sensing AC voltage electric field, the meter will display “—-” and the buzzer issued “drop, drop” alarm sound. As the intensity of the induction electric field increases, the more horizontal sections of “—-” displays on the LCD, and the higher the sound frequency of the buzzer

Note: When the tested electric field voltage is ≥ AC 100V, pay attention to whether the conductor of the measured electric field is insulated to avoid electric shock.

Automatic shutdown function

In order to save power consumption and prolong battery life, the meter will turn on automatic shutdown function by default after it is turned on and displays “APO” symbol on the screen. If the user does not operate the meter within 14 minutes, the meter will beep 3 times to prompt. If there is still no operation, after another 1 minute ,the meter will have a long beep and automatically turn off the function, and enter the low-power sleep mode. If you want to wake it up , you can press the select key to turn it on. Press the SELECT button to turn it on, the automatic shutdown function will cancel, and the LCD does not display the “APO” symbol. After cancel the automatic shutdown function, the meter will not automatically shut down, but there will have prompt sound every 15 minutes.
