Review: J'ai installé 2 de ces lecteurs pour surveiller l'état des 2 batterie de mon vehicule, une pour la batterie principale et l'autre pour la batterie auxiliere. J'en suis entièrement satisfait.
Review: Accurate and easy to install, just hook it to your battery and run your hot cable through the sensor. I use it on my motorcycle and it clearly shows my voltage and draw/charging status. Went a little bonkers when I drove through a downpour but started working again once it dried out. If you have any questions about your charging system get this meter!

## Features

- Dual display: Display Voltage and (+ -) Current at the same time; Power supply: DC 5~100V; Voltage test range: 0~300V; Current test range: ±0~100A
- Through-hole design: Easy Wiring; Measure positive or negative current; No current direction limitation
- Electrically isolated from high voltage power source which eliminates risk to delicate monitoring equipment and also minimizes safety concerns
- Compatible with large wire; Diameter of the sensor hole is 3/4 inch (19 mm)
- Loop through sensor multiple times to strengthen signal. For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps
