• Level the orientation flat on the probe assembly using a standard bubble level and tighten the packing nut to secure the assembly. To optimize
the repeatability of the verification process, the position and orientation of the probe assembly should be identical every time the process is
performed.
• Attach the regulator assembly with the interconnecting hose to the inlet quick disconnect fitting on the probe assembly if it is not permanently
installed.
• Attach the calibration gas supply, typically compressed air (or Nitrogen), to the inlet side of the regulator assembly. Back out the pressure con-
trol regulator. Open the supply valve to the VeriCal pressure regulator box.
• Slowly apply 100 PSIG to the VeriCal setup and verify that the system is leak free using a liquid leak detection fluid on all junction points. This
should also ensure a steady flow across the sensors and remove any debris that might be on the thermowells or the outlet of the VeriCal tube.
Reduce the pressure on the system to 25.0 PSIG.
• Open the ST100 Configurator application via the USB connection to the ST100. Go to the Process Data tab for the appropriate FE (Flow Element).
Be ready to record this information on the In-Situ VeriCal Data Sheet.
• The instrument is now in the VeriCal configuration and ready to establish a set of “Field Baseline Data.”
