8. The default values of the alarm variables will be set as follows:
Direct‐Acting Instrument
(Span = Upper Range Value - Lower Range Value
Alarm Variable Default Alarm Value
Hi‐Hi Alarm Upper Range Value
Hi Alarm 95% span + Lower Range Value
Lo Alarm 5% span + Lower Range Value
Lo‐Lo Alarm Lower Range Value
PV alert thresholds are initialized at 100%, 95%, 5% and 0% span.
PV alert deadband is initialized to 0.5% span.
PV alerts are all disabled. Temperature alerts are enabled.
D If Density mode was chosen, setup is complete.
D If Interface or Density mode was chosen, you are prompted to enter the specific gravity of the process fluid (if
interface mode, the specific gravities of the upper and lower process fluids).
Note
If you are using water or weights for calibration, enter a specific gravity of 1.0 SGU. For other test fluids, enter the specific gravity
of the fluid used.
For temperature compensation, go to Manual Setup. Under Process Fluid select View Fluid Tables. Temperature
compensation is enabled by entering values into the fluid tables.
Two data specific gravity tables are available that may be entered in the instrument to provide specific gravity
correction for temperature (refer to the Manual Setup section of the instruction manual). For interface level
applications, both tables are used. For level measurement applications, only the lower specific gravity table is used.
Neither table is used for density applications. Both tables may be edited during manual setup.
Note
The existing tables may need to be edited to reflect the characteristics of the actual process fluid.
You can accept the current table(s), modify an individual entry, or enter a new table manually. For an interface
application, you can switch between the upper and lower fluid tables.
