  • The PosiTest HHD uses pulsed DC technology to detect flaws. Instead of a continuous high-voltage output, the PosiTest HHD emits a precise pulse of high-voltage 30 times per second. This technology is much easier to ground, and safer, reducing the possibility of the exterior of the object becoming charged. The advanced circuitry is capable of maintaining a precise voltage output over the full range of 0.5-35 K-V in a single instrument. To alter the set voltage, simply choose the voltage selection menu option, and use the plus and minus buttons to adjust.
