Hall ammeter introduction
This is a Hall ammeter for measuring DC current. Breaking the use of ordinary metal shunt ammeter limitations and restrictions. This meter adopts super power supply voltage range: DC5-120V, it can be very convenient to directly measure the battery voltage of electric cars, automobiles and so on, one meter for two purposes.
Because the sensor and the measured wire electrical completely isolated role. With WLS-HVA100 you can measure both forward and reverse current. It can measure the current in the +VCC power line, the current in the -VCC power line, and the current in the "ground" line. As long as it is the measurement of direct current, it can be measured there, using it you can measure as you like.

Product Advantage
1. Unique sensor center hole design, the wire directly from the hole through, no need to cut the wire.
2.This meter can measure the current of the positive and negative poles of the power supply as you like, without worrying about the common ground of the ammeter.
3. High reliability, high current shock resistance, will not be current shock damage ammeter.
4. Due to the unique current channel, it can measure the current stably for a long time at full scale without affecting the life.
5. Adopting super bright emerald green LED display, it can be clearly displayed even in outdoor during daytime.
6. It can measure forward and reverse current, showing + current in forward direction and - current in reverse direction.
7. The power supply adopts switching type step-down design, which can be used for long-term maximum voltage 120V power supply without any pressure.
8. The voltage resistance value between the measuring wire and the measuring wire is up to 2KV.

Back button instruction
Short press the button on the back to switch the display mode to three display modes: current and voltage display mode / single current display mode / single voltage display mode. (Note: The measured voltage is the voltage value of the power supply of the ammeter)
Current and voltage display mode switching method
1. Short press the button on the back, the screen will display "A", which means it is single current display mode, only current value is displayed.
2. Short press the button on the back again, the screen will display "A U", indicating that this is the current-voltage rotating display mode, the screen takes turns to display the voltage value and the current value (Note: When the current value is displayed, the screen will flicker. (Note: When the current value is displayed, the screen will blink. When the voltage value is displayed, the screen will not blink).
3. Press the button on the back again and the screen will display "U", indicating that this is a single voltage display mode, which only displays the supply voltage value of the meter head.
4. Long press the button on the back of the 2S and then release, the screen will display "CCC" can be the current current value of zero.
Note: The operation of the key is stored in the chip and saved after power failure. So what mode it was in before the power failure, what mode it will be in after the power failure and reboot.
Note: In "current and voltage rotating display mode", when the current value is displayed, the screen will flash vividly as a reminder.
