Place the static contact of the vacuum chamber into the fixed coil, connect the high‑voltage line to the moving terminal and the signal line to the coil’s signal terminal.
Do not touch the high‑voltage output lines during power‑on or power‑off to avoid electric shock.
The tester contains 43 pre‑loaded measurement curves covering almost all domestic and foreign chamber types.
