DC 200A Hall Current Voltmeter Isolated Digital Voltage Current Meter w/ Anti-reverse Connection  

Description:
-This meter uses a super power supply voltage range: DC 5-120V, which can directly measure the battery voltage of electric vehicles, automobiles, etc., with one meter for dual purposes.
-The sensor is electrically isolated from the wire to be measured. With WLS-HVA200 you can measure both the forward current and the reverse current. It can measure the current of the +VCC power line, the current of the -VCC power cable, and the current of the ground wire. You can use it to measure whatever you want.
-Inside WLS-HVA200 there is an accurate, low-temperature drift, high-sensitivity Hall current sensor that has been accurately calibrated. The current channel with an internal diameter of 20mm allows the user to measure any current without destroying, shortening, or changing the original current path to achieve a seamless upgrade of the measurement system.
-The current channel inside WLS-HVA200 is completely independent and isolated, and the withstand voltage between it and the measured current conductor is as high as 2KV. Therefore, WLS-HVA200 can measure various high-voltage application environments without the need for photoelectric isolation, because it is completely isolated from the current channel. This can effectively reduce costs and improve system reliability.

Features:
(1) The unique hole design in the middle of the sensor allows the wire to pass through the hole directly without cutting the wire.
(2) This meter can measure the current of the positive and negative poles of the power supply at will, without worrying about the common ground problem of the ammeter.
(3) High reliability, high current impact resistance, and will not damage the ammeter by current impact.
(4) Due to the unique current channel, the full-scale and stable current can be measured for a long time without affecting the life.
(5) Using super bright emerald green LED display, it can be clearly displayed outdoors during the day.
(6) It can measure forward and reverse currents, display +current in the forward direction and -current in the reverse direction.
(7) The power supply adopts switch-type step-down design, which can be used for long-term maximum voltage 120V power supply without pressure.
(8) The withstand voltage between the wire to be measured is as high as: 2KV

Advantage:
1. Perforated, isolated, non-destructive measurement.
2. The positive and negative bidirectional current of charge and discharge can be measured.
3. The reset button is easy to operate.
4. Switch-type step-down design, not hot.

Positive and negative current display instructions:
The decimal point on the far right of the LED digital tube represents a negative sign, and when it is lit, meaning that the measurement shows a negative current.

 

Instructions:
Step 1: connect the DC 5-120V power supply to "power positive" and "power negative". It is powered by an ultra-wide power supply DC 5-120V.
Step 2:  pass the wire to be measured through the hole in the middle of the sensor.

Instructions for the buttons on the back:
Short press the button on the back to switch the display mode to three display modes in turn:
[1] Current and voltage alternate display mode.
[2] Single current display mode.
[3] 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", indicating that it is in single current display mode, and only current value is displayed.
(2) Short press the button on the back again, the screen will display "AU", indicating that the current and voltage alternate display mode at this time, the screen alternately displays the voltage value and current value (Note: When the current value is displayed, the screen will flash. Display. When the voltage value, the screen does not flash).
(3) Short press the button on the back again and the screen will display "U", indicating that it is in single voltage display mode, and only the power supply voltage value of the meter head is displayed.
Long press the button on the back of 2S and release it, the screen will display "CCC" to clear the current current value.

Note:
-The operation of the button is stored in the chip and saved after power off. So what is the mode before the power is off, and what mode is the restart after the power is off.
-In the "current and voltage alternate display mode", when the current value is displayed, the screen will flicker vividly.
