According to the international standard design, each channel of the system has an independent constant-current source and constant-voltage source The internal electrical power supply uses the high efficiency switching power supply, the energy conservation effect isremarkable, each power tube has the independent protection circuit, guarantees the Equipment works with safety and reliability. Measure adopts four wire method, decrease contact error, increase measure precision. 1450 * 380 * 1780(mm) 350KGS.
