4. “Full Tank Blanking”:
Using full tank programmable calibration, select distance to the
probes that covers any unwanted echoes close to the probes. To
activate this, go to “Tools” and click on “Full Tank Blanking” and
wait for the conformation.
5. “Set Loss of Echo Time”: (Not applicable for microwave probe.)
6. “Damping ON” / “Damping OFF”: In case of waves or turbulence on
liquids increase the damping time. This will slow down the probe
response. Do not use it for small tanks with fast rate of liquid
change.
7. “Solid Material/Liquid Materials”: (Not applicable for microwave
probe.)
8. “Vaporized Liquid High Power”: (Not applicable for microwave
probe.)
9. “Select Burst Power”: Used to change the transmit pulse width (in
microseconds). The selected pulse is used in the dusty and noisy
tanks (for solids applications) in case of noise error.
10. “Select Filter”: Used to change the filter width. The filter width
defines the range of allowed noise. The echo timer is ignored if it is
out of defined filter range.
m. “File” menu options:
1. “DataLogging (in Excel format)”: Default is set to ON. Select
“DataLogging (in Excel format)” from “FILE” menu to collect history
data for current and temperature in MS Excel format. Path for data
collection: C:\Program Files\um_probe\GATEWAYPC\DATA\yyyy
mm dd\sensorID\
Data is collected for each sensor ID. The current is collected in 1
hour data files and temperature is collected in 24 hours data files.
Use chart wizard in MS Excel to create the graph and view current
and temperature data. The current data is collected every 0.5
second and temperature is collected every 1 minute.
2. “Profile Logging”: Stores profile every 1 minute. Profile Viewer is
used to view stored history profiles. Profiles are stored in MS Excel
format in C:\Program
Files\um_probe\GATEWAYPC\LOG\year_month_day\sensorID\
directory.
