DO30-VI type AC multi-function calibrator


DO30-VI AC multifunctional calibrator (improved type) is suitable for calibrating and inspecting various AC current, voltage, frequency, phase, power and power factor meters below level 0.5. It can also be used as a high-stability test power supply to calibrate AC current, voltage, and power meters above level 0.2 in conjunction with high-level standard tables. Equipped with a standard test coil (optional), it can calibrate AC clamp ammeters (0~1000A) below level 1.
