A - 1 OR 2 POINT LEVEL OR DISTANCE TEACH-IN PROCEDURE
This function identifies the relationship between the transmitter display and real measure-
ments via entering 1 or 2 (point) distance measurements between the fluid and the base of
the sensor.
- To obtain the best accuracy it is advised that a 2 point Teach-In is undertaken and the
reference points are at the extremity of the application (level at minimum and maximum).
- The 2 point Teach-In will also define the sound velocity within the application if they have
not been determined or defined.
Steps for successful measurement:
1 POINT LEVEL OR DISTANCE TEACH-IN:
2 POINT LEVEL OR DISTANCE TEACH-IN:
- Complete the steps for the 1 point Teach-In although ensure that the reference points
are at the extremity of the application (Min. and Max.).
- Select ‘END NO‘.
- Fill or empty the tank/vessel to the new reference level and measure the distance.
- Enter the distance in the appropriate units and the transmitter will automatically
calculate the difference between the distance entered and actual distance measured for
a second time. (approx. 3 seconds).
- Select ‘VALID Y‘ to validate the option or ignore and advance to the next parameter.
1st Point
2nd Point
- Bring the fluid to a known distance or level.
- Enter the TEACH-IN function, then select
‘TEACH Y‘.
- Enter the distance or level of the 1st Point:
the transmitter automatically calculates the
difference between the entered and
measured values (this takes about
3 seconds).
- Now you can choose 'END NO' to perform a
2-point-Teach-in (see next paragraph) for
precise measurement.
- Select 'END YES' to exit the 1-point-Teach-in;
Here you can validate the 1st measurement
by choosing 'VALID Y' or ignore it by selecting
'VALID N'.
