Volt Meter (12v Systems) VM-1
- Input Range: 6v-30v
- Voltage Reading Range: 10.1v - 15.8v
- Accuracy: +/- 0.15v (due to the nature of a bar graph)
- 100% Analog circuitry allows for near instantaneous voltage accuracy versus a traditional digital voltage meter.
- Response time from one end of range to the other is less than 200 milliseconds.
RED WIRE= +
BLACK WIRE = GROUND
YELLOW WIRE = REMOTE TURN ON
Created by Steve Meade designs (made in China) I'm very happy with this product, I would definitely buy another for my k20 truck
Did a test with it on the battery along with a multimeter and they showed the same, then did a bit of testing with music playing and heavy amplifier current draw and the update speed on voltage is the fastest i have ever seen. I do heavily recommend this for people who wanna know whaddup on the electrical. Staying above 13V on burps :D
I have to say anyone with a audio build this is a must have to keep track on ur voltage at all times great product
Best volt meter on the market! Outstanding sensitivity to voltage readings. Easy hookup with some extra runs of 18gauge wire to the amplifier to see your voltage real time at the amp rather than at the alternator, to insure adequate voltage is being seen by amplifier! Down4sounds fast shipping tome and cost was the cherry on top!
