Page 4: Introduction
Volumetric or standardized flow readings are obtained with the push of a button. The DryCal 800 can be set to take flow readings manually, one reading at a time, or automatically in the continuous auto-read mode. The DryCal 800 can be programmed for up to 100 readings in an averaging sequence.

Page 7: Measure, Operations And Date/Time Delay Screen
Measure Screen The Measure screen allows you to capture and observe instantaneous flow data. During operation, the measured flow rate, reading number, standardization information, and average readings are displayed at the top. Gas pressure and temperature inside the tube are displayed on a constant basis regardless of whether the unit is operating. By pressing on the blue and grey portions of the screen allow you to access additional user-defined parameters.
Page 8: About, Diagnostics, Setting User Preferences
Setting User Preferences The DryCal 800 offers enhanced electronics options to allow the user to define parameters specific to an application. These parameters may be entered from the Operation screen or by pressing the blue section of the Measure screen.
Page 9: Sensor Factor, Ptvm, Standardized Or Volumetric And Number In Average
“Sensor Factor” As applicable, change the sensor factor from its default value of 1.000 to the value provided by the MFC or MFM manufacturer. See Using Sensor Factors. “PTVM” PTV stands for Piston Tare Value, which is the amount of gas that passes around the piston during measurement. All DryCal calibration equipment has a factory set PTV that is stored in the memory of the DryCal cell.
