Review on 🔒 Enhanced Installation Access: NLD100 by Marco Cervantes

I bought this to monitor the voltage in my system, very pleasing to the eye, very easy to install. which doesn't mean much to me, I earn my living with electronics. small footprint and easy-to-read display in sunlight. Mine needed some calibration as I was able to test it with a Fluke 5500A (very accurate calibrator) it was slightly off from 13.8 to 11.7 volts DC. Easy to set up if you have an accurate source. Now it shows 13.8 volts DC on the button. Don't confuse this with an accurate voltmeter, it shouldn't be used that way. Limited selection. A range of at least 50 volts would be nice. But overall I like this little guy because it's cheap and does what I need it to do. If you're not worried about 100% accuracy, then this option is for you.
