Finding The Best Automotive Voltmeter Of 2018 (Buyer’s Guide)

Note: only display and shunt are included. It doesn’t include any wire or accessories. Large-screen lcd (display voltage, current, active power, energy at the same time). Store energy data when power off(can be reset to 0). The blue backlight can be turned on/off manually. Voltage test range: dc 6.5~100v; current test range: 0~100a. With overload alarm function(if active power is larger than threshold, backlight and power will flash).

When engine running(do not drive), the led display: . Between 13.5 to 14.5 (12v car). Between 26.0 to 28.0 (24v car). Attention: for dc 12v or 24v car. Measuring range: dc 8v-30v+/-%1. What kind of batteries is healthy. This digital gauge displays the voltage of batteries in the car. With high brightness of led there is no difficulty in seeing the display. Powered by car cigarette lighter charger. Installment: insert the jack of the product into a cigar socket. Constantly monitor battery voltage, extend and protect the battery and engine life. Installment: clean the cigar socket. Insert the jack of the product into a cigar socket.
