Specifications:
Size: 120*60mm/4.72*2.36"
Material: ABS
Safety notice:
To avoid possible electric shocks, fires, and personal injuries, read safety precautions before using them. 
Please only use the product for specified use, otherwise it may weaken the protection provided by the product.
1. Please check the case before using the product. Check for cracks or plastic defects. Please check the insulator near the input port carefully.
2. Please use the correct gear setting and measure within the specified range according to this manual.
3. Do not use this product in explosive gas or steam or in wet environment.
4. When the DC voltage to be measured is higher than 36V, or the AC voltage is higher than 25V, it may cause serious harm to human body. Users should pay attention to avoid electric shock.
5. Please select the correct test gear and range so as to avoid instrument damage or personal injury. When the measured parameters exceed the instrument range, the screen will display "OL".
6. When the battery voltage is low, it may affect the accuracy of the test results. Please replace the battery in time. Do not use this product when the rear cover of the battery is not properly closed.
Measuring method:
Measuring DC / AC voltage
1. The threshold voltage of this product is 0.8mV. When the measured voltage is higher than 0.8mV, the product will display readings.
2. Insert the red pen into the right socket and insert the black pen into the public socket.
3. AC and DC voltage can be automatically identified.
4. Contact the correct test points on the circuit with the pen probe.
5. Read the voltage displayed on the display screen.
Measuring resistance:
1. This product can automatically identify resistance measurements.
2. Insert the red pen into the right socket and insert the black pen into the public socket.
3. Contact the desired circuit test point with a pen probe.
4. Read the resistance measured on the display screen.
Test and break:
1. This product can automatically identify on-off test.
2. Insert the red pen into the right socket and insert the black pen into the public socket.
3. Use the probe to receive two points of the circuit to be tested.
4. If the resistance value is less than 50 ohm, the buzzer will ring, and the central indicator lamp will always shine.
Contactless voltage detection:
1. Press the NCV key long to enter NCV mode and keep long press.
2. Take this product to move around, if the built-in inductor induction to the alternating current electromagnetic field, the product built-in buzzer will emit a "beep" sound, the stronger the electromagnetic field, "beep" sound faster, the instrument central indicator will flicker.
Measuring current:
1. By inserting the pen into the current channel, the product will automatically switch to the current measurement mode, which can automatically identify the AC and DC current.
2. Insert the red pen into the left Jack and insert the black pen into the public socket.
3. Use the probe to receive two points of the circuit to be tested.
4. Read the current value on the display screen.
5. When the 2A input is greater than the current, the measuring time should be less than 3 seconds.
6. When the pen is inserted into the current jack, without any measurement, the product will continue to alarm every four seconds, warning to avoid misoperation.
Function key:
Power key: press the button for 2 seconds to turn on / off the product. If there is no measurement operation in 15 minutes after starting, the product will be automatically turned off. Before the automatic shutdown 1 minutes, the product's built-in buzzer will send out five "tick" reminders. If you want to cancel the automatic shutdown function, you should hold down the NCV key and then turn on the machine, then turn off the five sound and cancel the automatic shutdown.
H/ short press the key, and the product will maintain the current readings on the LCD screen. If you press this button for more than 2 seconds, you can turn on the backlight and flashlight at the same time; if you press it again, you can turn off the backlight and flashlight.

NCV: If you press this button for a long time, you will enter NVC mode. You can't let go during the measuring process. If you let go, you will exit NCV mode. NCV measurement can not be carried out under current mode.

Battery: 7th battery (without battery delivery)

Notes:
1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
2. Please allow slight measuring deviation due to manual measurement.
