IMPORTANT:
At the next prompt, the kinematic viscosity values
entered must be in the range of 0.045 to 10000*10-6
ft^2/s or m^2/s. The values will appear as ft^2/s if the
meter is set for English units or m^2/s if the meter is
set for metric units.
[ENT] to accept the current Kin Viscosity value or enter a new
8. Press
value (with up to three decimal places) and press [ENT].
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 1-33. 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.
