WLS-TVA100 100A Voltage Current Meter Voltmeter Ammeter with Anti-reverse Connection Protection

WLS-TVA100 100A Voltage Current Meter Voltmeter Ammeter with Anti-reverse Connection Protection

Description:
This Hall ammeter can measure DC current. It uses a Hall current sensor, breaking the limitations of ammeters that use common metal shunts. Using super supply voltage of DC5-100V, it can directly measure the battery (battery is not included) voltage of electric vehicles, automobiles, etc.

Because the sensor is completely electrically isolated from the measured wire, it can measure both positive and negative currents. It can measure the current of the +VCC power cable, the current of the -VCC power cable, and the current of the "ground" wire.

Features:
- Integrated voltage and current meter
- Using isolated and non-destructive measurement, users do not need to worry about problems caused by common ground
- To measure positive and negative currents
- The surface of the panel is waterproof, and the display glass and housing are made of one-piece injection molding
- Ultra-wide power supply voltage range: DC5-100V; using switch-type step-down design, the meter is not getting hot
- Anti-reverse connection protection: the meter will not burn when wires are connected in the wrong directions

Package Included:
- 1 x Meter with Hall Sensor

Note:
- Battery is not included.
- If you need a sensor extension cable, please contact us.

Wiring:
- Yellow cable is connected to the positive pole of the measured voltage
- Red cable to the positive pole of power supply
- Black cable to the negative pole of power supply

Button Operations:
(1) Press and hold the button on its back for 3 seconds and release the button immediately. In this way, the current zero point can be cleared (attention: only when there is a current displayed at no-load, it is necessary to clear it in this way. Generally, it is not necessary to do so).
(2) Press and hold the button on the back for more than 6 seconds to restore the current and voltage factory calibration (attention: the user only needs to do this when the current and voltage measurement is inaccurate. Generally, this operation is not required).
