📊 bayite Pack of 5 Three-Wire Calibratable DC Mini Voltmeter: Monitor Car/Motorcycle Battery Voltage with 0-30V Range, Mountable Tester Gauge, 0.36" Blue LED Panel Display Review

The product connects easily and works great for the first two hours of use. Then, after turning off the connected devices and turning them back on a third or fourth time (I only run monitored devices during the day), two of those digital readings smoked and then disappeared. I have ordered 5 and so far 2 out of 5 have been plugged into a 12V DC charger and both have stopped working. Continuation: now all 5 are blown. The maximum voltage during operation was 13.2 V DC. All 5 turned off after the

They all appear to be accurate and only one of them had to be set to 0.1v based on my fluke gauge. Bright display, easy to read. Like three wires configured to read the voltage of the same or a separate device. I do not like it. Since there is no frame you will need a CNC machine to cut the exact hole to install them and still look good. See image. The wires come out from the top of the board. See other picture. So if you mount it through the panel. You'll need a couple of washers to position…

I hooked it up to read from zero to just over 5 volts and all five read the same. That tells me they're pretty good! Very bright (adjustable) and responsive. I have bought several of these kits. Caution: The wires are very small and brittle, almost impossible to strip, and are attached to an equally microscopic end of the wire with a microscopic amount of solder. Be careful with this! (Yes, I successfully connected the wires, but trust me, you don't want that!) As long as you're careful not to…

Pros: Looks nice. Its clear and easy to read 7-segment LED display. Very easy to use, only 3 wires. Cons: The input impedance is only 120 kOhm. As such, it will draw significant current from your load. With this thing, you don't have to track high-impedance signals. So you can't connect it directly to most sensors; must buffer the output of the sensor with an amplifier. You could at least buffer the inputs with an op-amp, adding only 3 cents to the cost. Another downside is that the entrance is

I love these displays, they work pretty well for their money. I do a lot of research with cells and I always want to have an idea of their voltage. Note: If you really need to measure low voltage, e.g. B. below 3 volts, you need an external power supply or battery. to power each display. This makes sense because if you test a dead (zero) battery with these displays, you won't see any data. above 3 volts they work as expected. One thing to note: I had to calibrate one of the blocks. I compared…
