Menu - Diagnostics
When you right-click on the Transmitter Diagnostics tab, a context menu appears. The items
that appear depend on the HDLT mode:
 Report Setup - Allows you to select a report file and a report printing program.
 Report - Generates a report of the HDLT parameters.
 Detach Trend - Removes the Trend display from the tabbed dialog and creates a
separate display.
 Help - Displays the help file at the Monitor tab instructions.
Fields
Continuous Diagnostic
Data
Displays data useful for prediction of life of the transmitter and other
components of the process affected by the liquid flow. The HDLT
tracks the amount of time the tank is empty, full, or working (pow-
ered on). In addition the HDLT sums the increases in tank level. When
used in a batch process where the tank is not filled and emptied at
the same time, this measurement is a tank totalizer.
Reset Data Causes the continuous diagnostic data to be set to 0. Any values
stored before the reset are lost.
Auto Tune Clicking Auto Tune runs a routine that determines the best parame-
ters for smoothing the output signal from the HDLT.
Save Coef. Clicking the Save Coefficients button saves the three Smart Filtering
Coefficients above into the HDLT non-volatile memory.
Sensor Test Performs a sensor self test. This procedure must be run ONLY IF THE
LIQUID LEVEL IS STABLE to avoid going to failsafe mode. This test is
performed when the level is out of service.
Specific Gravity Meter When on, the meter displays the specific gravity continuously if the
specific gravity meter has been calibrated.
