Running a Test

Once a test has begun, a RUN-TIME MENU of current values will be shown. The
user may control all available parameters of the instrument from this menu.

Under the Pressure column, the user can turn the water supply to the pressure
vessel on or off and can turn the pump on when the cylinder is filled.

Under the Temperature column, the user can select between AUTO and MANUAL
temperature control. When in MANUAL mode, the user can adjust the temperature
set point as well as turn cooling on/off.
