Functionality Test Performed on Turbo Pumps

We ran the functionality test on the main turbopump at EX, MX and MY. The scroll pump is started to take pressure down to low 10^-02 Torr, at which time the turbo pump is started, the system reaches low 10^-08 Torr after a few minutes, then the turbo pump system is left ON for about 1 hour, after the hour the system goes through a shut down sequence.
No issues were encountered while performing the functionality test on this station.
