Previous: Trouble During Pre-Cool
The computer software maintains the pressure in the pre-cool lines to
keep the pulse tube cooling power high. Occassionally, the pulse tube
cooling power will drop to zero before the temperature gets low enough
to trigger the software to lower the pressure in the pre-cool lines.
To solve this, pulse either V4 or V7. The temperature should fall very
quickly, and the software should pick up automation again.
