DigitalFlow™ DF868 Multipurpose Ultrasonic Liquid Flowmeter Programming Manual (2-Channel) 49
Chapter 1. Programming Site Data
The Temperature and Kin Viscosity prompts repeat until the number of pairs specified have all been entered. After
entering all the pairs, the meter returns to the User Program menu. If desired, repeat the above sequence to enter
additional tables for the other fluids (up to 3). To activate a table, refer to Calculating Kinematic Viscosity on page 26.
Activating this feature causes three changes to the standard software:
• Whenever the temperature compensation option is active, the diagnostic parameter Fluid Temperature appears
for display and data logging.
Note: If you are logging via IDM or PanaView, the Fluid Temperature diagnostic parameter is available even if the
temperature compensation option is deactivated. However, the units will be displayed as NOT ACTIVE.
• If the current fluid temperature is outside the range of the tabulated values, then the last value that was within
the tabulated range will be used instead.
• If the fluid temperature is in error due to an invalid analog input condition, the DF868 will continue to use the last
valid reading.
IMPORTANT: The tables entered for this feature are global, meaning that the same tables will be used for all sites and
channels in the meter. Thus, editing the tables in any one site file will alter the values for all other site
files. Also, the tables are included as part of the site upload/download functions. For example, if you print
out a site file, the current contents of the tables will also be printed.
