The temperature limit sensor must be placed in the Quartz Cold Trap, and only 1/3 of it should be exposed. If it exceeded 50 degrees, the power would be cut off.
- It is recommended to turn off the lights and let the supporting low-temperature cooling circulation device continue to run for 30 minutes before stopping the operation to avoid damage to the instrument due to excessive temperature.
