Performance Characteristics of Product
Executive standard: GB/T4074.3-2008/IEC60851-3; Inspection standard: JB/T4279.4-2008
Used to measure the spring back characteristic of enameled round wires with nominal conductor diameter of between 0.080mm and 1.600mm;
Number of winding turns: 5 turns and a half
Stop accurately at zero position of the scale after automatic winding
As soon as the value of spring back angle stop counting, the dial will stop to rotate immediately, so that the value displayed on LED and read on the dial are the same.
Sensor is unnecessary to be adjusted for samples of different specifications
Coils loosen slowly during spring back, no action of spring back or jump suddenly.
Application of SCM control allows for fast operation and strong anti-interference capacity;
