Signal Gain:
Is the strength of the interrogation pulse. MTS uses the
same electronics for all lengths and adjusts the signal based on the
order length. Do not change unless instructed to do so by the MTS
Factory.

Method – Enter Level Offset:
a calibration method that directly
changes the offset of the level measurement. The offset is the zero
reference point used in determining the level output. Do not use
without Factory guidance.
Product Offset:
the full length of the level transmitter including order
length, inactive zones, and mounting length. Do not change the Enter
Level Offset method without Factory guidance. The offset will change
after using the Enter Current Tank Level for the Product. The Product
Offset and Interface Offset are independent of one another.
Interface Offset:
the full length of the level transmitter including order
length, inactive zones, and mounting length. Do not change the Enter
Level Offset method without Factory guidance. The offset will change
after using the Enter Current Tank Level for the Interface. The Product
Offset and Interface Offset are independent of one another.
User Configurable
Length Units:
the unit of measurement used for engineering units.
Default is inches if ordered in inches and mm if ordered in mm.
Options include inches, feet, millimeters, centimeters, and meters.
Method
– Enter Current Tank Level: a calibration method that
calibrates the level transmitter based off of one point of measurement.
Select Enter Current Tank Level from the Method drop down box. Go
to Product Level and enter value of current product level based off
of a manual measurement while the tank level is not changing. Go to
Interface Level and enter value of current interface level based off of
a manual measurement while the tank is not changing. Click Update
box in lower left corner when it appears. Level transmitter is now
calibrated.
9.1.6 Temperature settings
User Configurable
Product Zero:
Chang the Zero (LRV, 4mA) set point of the product
level. The set point needs to be in the active range.
Product Span:
Chang the Span (URV, 20mA) set point of the product
level. The set point needs to be in the active range.
Factory Set
Position:
The location of the temperature sensor in reference to the
end of the pipe.
Slope:
Calibration factor for the temperature sensor. Do not change
unless a new sensing element with temperature is ordered.
Intercept:
Calibration factor for the temperature sensor. Do not change
unless a new sensing element with temperature is ordered.
User Configurable
Temperature Units:
Change the units of measure for the temperature
settings. Options are Fahrenheit or Celsius.
Number of Averages:
Change the number of temperature readings
used in the rolling average.
