Page 4: Instrument Introduction
I、Safety rules and precautions 1. Please connect all test cables before starting up, such as printer cables; 2. Before measuring, please check whether the tube type is suitable for the vacuum tube to be tested for accurate measurement. 3. When starting up, shutting down and measuring, do not touch the high voltage line and magnetron current line to prevent electric shock. -

supply during the test is effectively suppressed, and the test is stable and reliable. The instrument uses the secondary sampling method to deduct the leakage current due to environmental factors, and considers the determination of the completely leaking vacuum interrupter during the measurement process, and truly achieves the correctness of the vacuum interrupter installed on the whole machine. - Page 6 data on the relationship between ionization charge and vacuum degree of almost all vacuum interrupters at home and abroad, and send their characteristic parameters to this series through mathematical processing. product. Therefore, this series of products have built-in measurement curves of almost all vacuum interrupters at home and abroad, which is unique among similar products at home and abroad.

Page 7: Test Principle
III、Test principle Using the different leakage currents of the ion current under different vacuum conditions to test and identify the advantages and disadvantages of the vacuum isolation chamber. The two contacts of the arc extinguishing chamber are separated by a certain distance, and the moving contact applies a high voltage pulse to the static contact to apply a negative ion current. -

Page 10: Wiring Instructions
VI、Instructions 1.Wiring instructions Keep the two contacts of the isolation room in a separate state, then wind the magnetron coil, and then insert the two plugs of the magnetron coil into the two red and black plugs of the magnetron current output. In addition, the high-voltage wire and the ion wire are respectively connected to the two contacts of the vacuum bubble (moving and contacts are not separated). - Page 11 strokes and fewer strokes. After checking, press 【Reset key】. Select parameter 6, start high voltage: At this time, the high voltage indicator light is on, high voltage is generated, and the last four digits of the display show the high voltage value in ten thousand volts. When doing this inspection, pay attention to the location of the high-voltage line to avoid danger.

the measurement result will be printed. ②The measurement steps performed by the computer in the instrument are as follows: Start the high voltage → measure the leakage current → turn off the high voltage → turn on the charging switch → the voltage reaches the specified value → start the magnetron current, measure the leakage current + ionization current, →...
