Review on IZTOSS 12V-24V Universal LED Display Digital Voltmeter with Low Voltage Alarm for Car Motorcycle Auto Truck - Measure Voltage 7-30V by David Flores

I really like the colorful display. It's been on my wish list for months. But to be honest, he's much more attractive in studio photos. Virtually invisible in direct sunlight. The normal operating range of my machine is between 13.9 and 14.1, which means the entire bar graph is on all the time. The bar graph scale should be logarithmic and 12V at top dead center and the last element represents 15V. UPDATE: I was able to improve daytime visibility by putting a tint film over it.
