- 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

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'.
