Vacuum tester panel and external wiring diagram
Panel introduction:
1. Ion current output terminal: used to output the ion current required for testing.
(Leakage current sampling terminal)
2. Magnetron current output terminal: used to output the magnetron current required for
the test to accelerate the electron flow to reduce the influence of various external factors
on the measurement accuracy.
3. High voltage output terminal: used to output the high voltage required for testing. (Low
voltage 25,000 volts, high voltage 30,000 volts) For details, see 3.3.5 operating
instructions.
4. External power supply: Provide the working voltage required by the instrument.
AC220V±10% 50/60HZ
5. Power switch: the main switch to control the instrument.
6. Tube type: used to select the tube type corresponding to the test.
