| Standard Datcon Tachometers have a 270º pointer sweep, which operate on either 12 or 24 volts of direct current with reverse polarity protection. All Datcon tachometers are manufactured with a rugged meter movement incorporating a Floating Rest. This means that the tachometer pointer is free to float when power to the tachometer is removed. As voltage is applied to a properly installed tachometer the pointer will Snap to Zero. |
