发明名称 AN AUTOMATIC TESTING APPARATUS OF A CHARACTERISTIC OF PICTURE TUBE
摘要 <p>The circuit for automatically inspecting the characteristic of CRT with increased accuracy by sequentially and automatically measuring current or the current characteristic of the CRT includes a measuring range part for setting measuring range as the measure range of cathode cut-off current (COE2) or the measure range of the cathode maximum current (MIK), the relays (RL1-RL6) for relaying the current of a CRT, the volumes (VR1,VR2,VR3) for converting the cathode current to the voltage, and the digital voltage meter (DVM)</p>
