When building a test at temperatures above 190°F (87.8°C), the unit will
calculate and apply a minimum pressure to prevent the sample from
boiling. A pressure of 1,000 psi (6.9 MPa) is also required to get a good
transit time signal during UCA tests.
There are three types of steps:
• Ramp – This will increase the temperature or pressure up to the
target in a set number of minutes. You will be prompted for the
ramp time (hh:mm:ss) and target.
• Step – This will increase the temperature or pressure up to the
target as fast as possible. Enter the target in the "Target" box.
• Dwell – This will hold the current temperature or pressure for a set
number of minutes. Enter the time (hh:mm:ss) into the “Time” Box.
The maximum temperature setpoint allowed is 400°F (204.4°C). The
unit allows pressure setpoints between 100 psi (689.5 kPa) and 5,000
psi (34.5 MPa). The units of measure will be the same as entered in the
Setup menu. (See page 12 for setting UCA units and page 14 for
setting SGSM units.)
5. To edit an existing step, double click the step in the step list or highlight
the existing step and select the “Edit” button. Click OK when done.
6. Click the “OK” button to exit the “Setup” screen. The new Temperature
Profile will now appear in the “Available Profiles” list on the “Profile” tab.
